The Seven Lamps of Architecture/Chapter 7

by John Ruskin

CHAPTER VII

THE LAMP OF OBEDIENCE

I. It been my endeavour to show in the preceding pages how every form of noble architecture is in some sort the embodiment of the Polity, Life, History, and Religious Faith of nations. Once or twice in doing this, I have named a principle to which I would now assign a definite place among those which direct that embodiment; the last place, not only as that to which its own humility would incline, but rather as belonging to it in the aspect of the crowning grace of all the rest: that principle, I mean, to which Polity owes its stability, Life its happiness, Faith its acceptance, Creation its continuance—Obedience.

Nor is it the least among the sources of more serious satisfaction which I have found in the pursuit of a subject that at first appeared to bear but slightly on the grave interests of mankind, that the conditions of material perfection which it leads me in conclusion to consider, furnish a strange proof how false is the conception, how frantic the pursuit, of that treacherous phantom which men call Liberty: most treacherous, indeed, of all phantoms; for the feeblest ray of reason might surely show us, that not only its attainment, but its being, was impossible. There is no such thing in the universe. There can never be. The stars have it not; the earth has it not; the sea has it not; and we men have the mockery and semblance of it only for our heaviest punishment. In one of the noblest poems^[1] for its imagery and its music belonging to the recent school of our literature, the writer has sought in the aspect of inanimate nature the expression of that Liberty which, having once loved, he had seen among men in its true dyes of darkness. But with what strange fallacy of interpretation! since in one noble line of his invocation he has contradicted the assumptions of the rest, and acknowledged the presence of a subjection, surely not less severe because eternal. How could he otherwise? since if there be any one principle more widely than another confessed by every utterance, or more sternly than another imprinted on every atom, of the visible creation, that principle is not Liberty, but Law.

II. The enthusiast would reply that by Liberty he meant the Law of Liberty. Then why use the single and misunderstood word? If by liberty you mean chastisement of the passions, discipline of the intellect, subjection of the will; if you mean the fear of inflicting, the shame of committing, a wrong; if you mean respect for all who are in authority, and consideration for all who are in dependence; veneration for the good, mercy to the evil, sympathy with the weak; if you mean watchfulness over all thoughts, temperance in all pleasures, and perseverance in all toils; if you mean, in a word, that Service which is defined in the liturgy of the English church to be perfect Freedom, why do you name this by the same word by which the luxurious mean license, and the reckless mean change; by which the rogue means rapine, and the fool, equality; by which the proud mean anarchy, and the malignant mean violence? Call it by any name rather than this, but its best and truest, is Obedience. Obedience is, indeed, founded on a kind of freedom, else it would become mere subjugation, but that freedom is only granted that obedience may be more perfect; and thus, while a measure of license is necessary to exhibit the individual energies of things, the fairness and pleasantness and perfection of them all consist in their Restraint. Compare a river that has burst its banks with one that is bound by them, and the clouds that are scattered over the face of the whole heaven with those that are marshalled into ranks and orders by its winds. So that though restraint, utter and unrelaxing, can never be comely, this is not because it is in itself an evil, but only because, when too great, it overpowers the nature of the thing restrained, and so counteracts the other laws of which that nature is itself composed. And the balance wherein consists the fairness of creation is between the laws of life and being in the things governed, and the laws of general sway to which they are subjected; and the suspension or infringement of either kind of law, or, literally, disorder, is equivalent to, and synonymous with, disease; while the increase of both honour and beauty is habitually on the side of restraint (or the action of superior law) rather than of character (or the action of inherent law). The noblest word in the catalogue of social virtue is 'Loyalty', and the sweetest which men have learned in the pastures of the wilderness is 'Fold'.

III. Nor is this all; but we may observe, that exactly in proportion to the majesty of things in the scale of being, is the completeness of their obedience to the laws that are set over them. Gravitation is less quietly, less instantly obeyed by a grain of dust than it is by the sun and moon; and the ocean falls and flows under influences which the lake and river do not recognize. So also in estimating the dignity of any action or occupation of men, there is perhaps no better test than the question 'are its laws strait?' For their severity will probably be commensurate with the greatness of the numbers whose labour it concentrates or whose interest it concerns.

This severity must be singular, therefore, in the case of that art, above all others, whose productions are the most vast and the most common; which requires for its practice the co-operation of bodies of men, and for its perfection the perseverance of successive generations. And, taking into account also what we have before so often observed of Architecture, her continual influence over the emotions of daily life, and her realism, as opposed to the two sister arts which are in comparison but the picturing of stories and of dreams, we might beforehand expect that we should find her healthy state and action dependent on far more severe laws than theirs: that the license which they extend to the workings of individual mind would be withdrawn by her; and that, in assertion of the relations which she holds with all that is universally important to man, she would set forth, by her own majestic subjection, some likeness of that on which man's social happiness and power depend. We might, therefore, without the light of experience, conclude, that Architecture never could flourish except when it was subjected to a national law as strict and as minutely authoritative as the laws which regulate religion, policy, and social relations; nay, even more authoritative than these, because both capable of more enforcement, as over more passive matter; and needing more enforcement, as the purest type not of one law nor of another, but of the common authority of all. But in this matter experience speaks more loudly than reason. If there be any one condition which, in watching the progress of architecture, we see distinct and general; if, amidst the counter-evidence of success attending opposite accidents of character and circumstance, any one conclusion may be constantly and indisputably drawn, it is this; that the architecture of a nation is great only when it is as universal and as established as its language; and when provincial differences of style are nothing more than so many dialects. Other necessities are matters of doubt: nations have been alike successful in their architecture in times of poverty and of wealth; in times of war and of peace; in times of barbarism and of refinement; under governments the most liberal or the most arbitrary; but this one condition has been constant, this one requirement clear in all places and at all times, that the work shall be that of a school, that no individual caprice shall dispense with, or materially vary, accepted types and customary decorations; and that from the cottage to the palace, and from the chapel to the basilica, and from the garden fence to the fortress wall, every member and feature of the architecture of the nation shall be as commonly current, as frankly accepted, as its language or its coin.

IV. A day never passes without our hearing our English architects called upon to be original, and to invent a new style: about as sensible and necessary an exhortation as to ask of a man who has never had rags enough on his back to keep out cold, to invent a new mode of cutting a coat. Give him a whole coat first, and let him concern himself about the fashion of it afterwards. We want no new style of architecture. Who wants a new style of painting or sculpture? But we want some style. It is of marvellously little importance, if we have a code of laws and they be good laws, whether they be new or old, foreign or native, Roman or Saxon, or Norman, or English laws. But it is of considerable importance that we should have a code of laws of one kind or another, and that code accepted and enforced from one side of the island to another, and not one law made ground of judgment at York and another in Exeter. And in like manner it does not matter one marble splinter whether we have an old or new architecture, but it matters everything whether we have an architecture truly so called or not; that is, whether an architecture whose laws might be taught at our schools from Cornwall to Northumberland, as we teach English spelling and English grammar, or an architecture which is to be invented fresh every time we build a workhouse or a parish school. There seems to me to be a wonderful misunderstanding among the majority of architects of the present day as to the very nature and meaning of Originality, and of all wherein it consists. Originality in expression does not depend on invention of new words; nor originality in poetry on invention of new measures; nor, in painting, on invention of new colours, or new modes of using them. The chords of music, the harmonies of colour, the general principles of the arrangement of sculptural masses, have been determined long ago, and, in all probability, cannot be added to any more than they can be altered. Granting that they may be, such additions or alterations are much more the work of time and of multitudes than of individual inventors. We may have one Van Eyck, who will be known as the introducer of a new style once in ten centuries, but he himself will trace his invention to some accidental by-play or pursuit; and the use of that invention will depend altogether on the popular necessities or instincts of the period. Originality depends on nothing of the kind. A man who has a gift, will take up any style that is going, the style of his day, and will work in that, and be great in that, and make everything that he does in it look as fresh as if every thought of it had just come down from heaven. I do not say that he will not take liberties with his materials, or with his rules: I do not say that strange changes will not sometimes be wrought by his efforts, or his fancies, in both. But those changes will be instructive, natural, facile, though sometimes marvellous; they will never be sought after as things necessary to his dignity or to his independence; and those liberties will be like the liberties that a great speaker takes with the language, not a defiance of its rules for the sake of singularity; but inevitable, uncalculated, and brilliant consequences of an effort to express what the language, without such infraction, could not. There may be times when, as I have above described, the life of an art is manifested in its changes, and in its refusal of ancient limitations: so there are in the life of an insect; and there is great interest in the state of both the art and the insect at those periods when, by their natural progress and constitutional power, such changes are about to be wrought. But as that would be both an uncomfortable and foolish caterpillar which, instead of being contented with a caterpillar's life and feeding on caterpillar's food, was always striving to turn itself into a chrysalis; and as that would be an unhappy chrysalis which should lie awake at night and roll restlessly in its cocoon, in efforts to turn itself prematurely into a moth ; so will that art be unhappy and unprosperous which, instead of supporting itself on the food, and contenting itself with the customs, which have been enough for the support and guidance of other arts before it and like it, is struggling and fretting under the natural limitations of its existence, and striving to become something other than it is. And though it is the nobility of the highest creatures to look forward to, and partly to understand the changes which are appointed for them, preparing for them beforehand; and if, as is usual with appointed changes, they be into a higher state, even desiring them, and rejoicing in the hope of them, yet it is the strength of every creature, be it changeful or not, to rest for the time being, contented with the conditions of its existence, and striving only to bring about the changes which it desires, by fulfilling to the uttermost the duties for which its present state is appointed and continued.

V. Neither originality, therefore, nor change, good though both may be, and this is commonly a most merciful and enthusiastic supposition with respect to either, is ever to be sought in itself, or can ever be healthily obtained by any struggle or rebellion against common laws. We want neither the one nor the other. The forms of architecture already known are good enough for us, and for far better than any of us; and it will be time enough to think of changing them for better when we can use them as they are. But there are some things which we not only want, but cannot do without; and which all the struggling and raving in the world, nay more, which all the real talent and resolution in England, will never enable us to do without: and these are Obedience, Unity, Fellowship, and Order. And all our schools of design, and committees of taste; all our academies and lectures, and journalisms, and essays; all the sacrifices which we are beginning to make, all the truth which there is in our English nature, all the power of our English will, and the life of our English intellect, will in this matter be as useless as efforts and emotions in a dream, unless we are contented to submit architecture and all art, like other things, to English law.

VI. I say architecture and all art; for I believe architecture must be the beginning of arts, and that the others must follow her in their time and order; and I think the prosperity of our schools of painting and sculpture, in which no one will deny the life, though many the health, depends upon that of our architecture. I think that all will languish until that takes the lead, and (this I do not think, but I proclaim, as confidently as I would assert the necessity, for the safety of society, of an understood and strongly administered legal government) our architecture will languish, and that in the very dust, until the first principle of common sense be manfully obeyed, and an universal system of form and workmanship be everywhere adopted and enforced. It may be said that this is impossible. It may be so—I fear it is so: I have nothing to do with the possibility or impossibility of it; I simply know and assert the necessity of it. If it be impossible, English art is impossible. Give it up at once. You are wasting time, and money, and energy upon it, and though you exhaust centuries and treasuries, and break hearts for it, you will never raise it above the merest dilettanteism. Think not of it. It is a dangerous vanity, a mere gulph in which genius after genius will be swallowed up, and it will not close. And so it will continue to be, unless the one bold and broad step be taken at the beginning. We shall not manufacture art out of pottery and printed stuffs; we shall not reason out art by our philosophy; we shall not stumble upon art by our experiments, nor create it by our fancies: I do not say that we can even build it out of brick and stone; but there is a chance for us in these, and there is none else; and that chance rests on the bare possibility of obtaining the consent, both of architects and of the public, to choose a style, and to use it universally.

VII. How surely its principles ought at first to be limited, we may easily determine by the consideration of the necessary modes of teaching any other branch of general knowledge. When we begin to teach children writing, we force them to absolute copyism, and require absolute accuracy in the formation of the letters; as they obtain command of the received modes of literal expression, we cannot prevent their falling into such variations as are consistent with their feeling, their circumstances, or their characters. So, when a boy is first taught to write Latin, an authority is required of him for every expression he uses: as he becomes master of the language he may take a license, and feel his right to do so without any authority, and yet write better Latin than when he borrowed every separate expression. In the same way our architects would have to be taught to write the accepted style. We must first determine what buildings are to be considered Augustan in their authority; their modes of construction and laws of proportion are to be studied with the most penetrating care; then the different forms and uses of their decorations are to be classed and catalogued, as a German grammarian classes the powers of prepositions; and under this absolute, irrefragable authority, we are to begin to work; admitting not so much as an alteration in the depth of a cavetto, or the breadth of a fillet. Then, when our sight is once accustomed to the grammatical forms and arrangements, and our thoughts familiar with the expression of them all; when we can speak this dead language naturally, and apply it to whatever ideas we have to render, that is to say, to every practical purpose of life; then, and not till then, a license might be permitted, and individual authority allowed to change or to add to the received forms, always within certain limits; the decorations, especially, might be made subjects of variable fancy, and enriched with ideas either original or taken from other schools. And thus, in process of time and by a great national movement, it might come to pass that a new style should arise, as language itself changes; we might perhaps come to speak Italian instead of Latin, or to speak modern instead of old English; but this would be a matter of entire indifference, and a matter, besides, which no determination or desire could either hasten or prevent. That alone which it is in our power to obtain, and which it is our duty to desire, is an unanimous style of some kind, and such comprehension and practice of it as would enable us to adapt its features to the peculiar character of every several building, large or small, domestic, civil, or ecclesiastical. I have said that it was immaterial what style was adopted, so far as regards the room for originality which its development would admit: it is not so, however, when we take into consideration the far more important questions of the facility of adaptation to general purposes, and of the sympathy with which this or that style would be popularly regarded. The choice of Classical or Gothic, again using the latter term in its broadest sense, may be questionable when it regards some single and considerable public building; but I cannot conceive it questionable, for an instant, when it regards modern uses in general: I cannot conceive any architect insane enough to project the vulgarization of Greek architecture. Neither can it be rationally questionable whether we should adopt early or late, original or derivative Gothic; if the latter were chosen, it must be either some impotent and ugly degradation, like our own Tudor, or else a style whose grammatical laws it would be nearly impossible to limit or arrange, like the French Flamboyant. We are equally precluded from adopting styles essentially infantine or barbarous, however Herculean their infancy, or majestic their outlawry, such as our own Norman, or the Lombard Romanesque. The choice would lie I think between four styles: 1. The Pisan Romanesque; 2. The early Gothic of the Western Italian Republics, advanced as far and as fast as our art would enable us to the Gothic of Giotto; 3. The Venetian Gothic in its purest development; 4. The English earliest decorated. The most natural, perhaps the safest choice, would be of the last, well fenced from chance of again stiffening into the perpendicular; and perhaps enriched by some mingling of decorative elements from the exquisite decorated Gothic of France, of which, in such cases, it would be needful to accept some well known examples, as the North door of Rouen and the church of St Urbain at Troyes, for final and limiting authorities on the side of decoration.

VIII. It is almost impossible for us to conceive, in our present state of doubt and ignorance, the sudden dawn of intelligence and fancy, the rapidly increasing sense of power and facility, and, in its proper sense, of Freedom, which such wholesome restraint would instantly cause throughout the whole circle of the arts. Freed from the agitation and embarrassment of that liberty of choice which is the cause of half the discomforts of the world; freed from the accompanying necessity of studying all past, present, or even possible styles; and enabled, by concentration of individual, and co-operation of multitudinous energy, to penetrate into the uttermost secrets of the adopted style, the architect would find his whole understanding enlarged, his practical knowledge certain and ready to hand, and his imagination playful and vigorous, as a child's would be within a walled garden, who would sit down and shudder if he were left free in a fenceless plain. How many and how bright would be the results in every direction of interest, not to the arts merely, but to national happiness and virtue, it would be as difficult to preconceive as it would seem extravagant to state: but the first, perhaps the least, of them would be an increased sense of fellowship among ourselves, a cementing of every patriotic bond of union, a proud and happy recognition of our affection for and sympathy with each other, and our willingness in all things to submit ourselves to every law that could advance the interest of the community; a barrier, also, the best conceivable, to the unhappy rivalry of the upper and middle classes, in houses, furniture, and establishments; and even a check to much of what is as vain as it is painful in the oppositions of religious parties respecting matters of ritual. These, I say, would be the first consequences. Economy increased tenfold, as it would be by the simplicity of practice; domestic comforts uninterfered with by the caprice and mistakes of architects ignorant of the capacities of the styles they use, and all the symmetry and sightliness of our harmonized streets and public buildings, are things of slighter account in the catalogue of benefits. But it would be mere enthusiasm to endeavour to trace them farther. I have suffered myself too long to indulge in the speculative statement of requirements which perhaps we have more immediate and more serious work than to supply, and of feelings which it may be only contingently in our power to recover. I should be unjustly thought unaware of the difficulty of what I have proposed, or of the unimportance of the whole subject as compared with many which are brought home to our interests and fixed upon our consideration by the wild course of the present century. But of difficulty and of importance it is for others to judge. I have limited myself to the simple statement of what, if we desire to have architecture, we must primarily endeavour to feel and do: but then it may not be desirable for us to have architecture at all. There are many who feel it to be so; many who sacrifice much to that end; and I am sorry to see their energies wasted and their lives disquieted in vain. I have stated, therefore, the only ways in which that end is attainable, without venturing even to express an opinion as to its real desirableness. I have an opinion, and the zeal with which I have spoken may sometimes have betrayed it, but I hold to it with no confidence. I know too well the undue importance which the study that every man follows must assume in his own eyes, to trust my own impressions of the dignity of that of Architecture; and yet I think I cannot be utterly mistaken in regarding it as at least useful in the sense of a National employment. I am confirmed in this impression by what I see passing among the states of Europe at this instant. All the horror, distress, and tumult which oppress the foreign nations, are traceable, among the other secondary causes through which God is working out His will upon them, to the simple one of their not having enough to do. I am not blind to the distress among their operatives; nor do I deny the nearer and visibly active causes of the movement: the recklessness of villainy in the leaders of revolt, the absence of common moral principle in the upper classes, and of common courage and honesty in the heads of governments. But these causes themselves are ultimately traceable to a deeper and simpler one: the recklessness of the demagogue, the immorality of the middle class, and the effeminacy and treachery of the noble, are traceable in all these nations to the commonest and most fruitful cause of calamity in households—idleness. We think too much in our benevolent efforts, more multiplied and more vain day by day, of bettering men by giving them advice and instruction. There are few who will take either; the chief thing they need is occupation. I do not mean work in the sense of bread,—I mean work in the sense of mental interest; for those who either are placed above the necessity of labour for their bread, or who will not work although they should. There is a vast quantity of idle energy among European nations at this time, which ought to go into handicrafts; there are multitudes of idle semi-gentlemen who ought to be shoe-makers and carpenters; but since they will not be these so long as they can help it, the business of the philanthropist is to find them some other employment than disturbing governments. It is of no use to tell them they are fools, and that they will only make themselves miserable in the end as well as others: if they have nothing else to do, they will do mischief; and the man who will not work, and who has no means of intellectual pleasure, is as sure to become an instrument of evil as if he had sold himself bodily to Satan. I have myself seen enough of the daily life of the young educated men of France and Italy, to account for, as it deserves, the deepest national suffering and degradation; and though, for the most part, our commerce and our natural habits of industry preserve us from a similar paralysis, yet it would be wise to consider whether the forms of employment which we chiefly adopt or promote, are as well calculated as they might be to improve and elevate us.

We have just spent, for instance, a hundred and fifty millions, with which we have paid men for digging ground from one place and depositing it in another. We have formed a large class of men, the railway navvies, especially reckless, unmanageable, and dangerous. We have maintained besides (let us state the benefits as fairly as possible) a number of iron founders in an unhealthy and painful employment; we have developed (this is at least good) a very large amount of mechanical ingenuity; and we have, in fine, attained the power of going fast from one place to another. Meantime we have had no mental interest or concern ourselves in the operations we have set on foot, but have been left to the usual vanities and cares of our existence. Suppose, on the other hand, that we had employed the same sums in building beautiful houses and churches. We should have maintained the same number of men, not in driving wheelbarrows, but in a distinctly technical, if not intellectual, employment; and those who were more intelligent among them would have been especially happy in that employment, as having room in it for the development of their fancy, and being directed by it to that observation of beauty which, associated with the pursuit of natural science, at present forms the enjoyment of many of the more intelligent manufacturing operatives. Of mechanical ingenuity, there is, I imagine, at least as much required to build a cathedral as to cut a tunnel or contrive a locomotive: we should, therefore, have developed as much science, while the artistical element of intellect would have been added to the gain. Meantime we should ourselves have been made happier and wiser by the interest we should have taken in the work with which we were personally concerned; and when all was done, instead of the very doubtful advantage of the power of going fast from place to place, we should have had the certain advantage of increased pleasure in stopping at home.

IX. There are many other less capacious, but more constant, channels of expenditure, quite as disputable in their beneficial tendency; and we are, perhaps, hardly enough in the habit of inquiring, with respect to any particular form of luxury or any customary appliance of life, whether the kind of employment it gives to the operative or the dependant be as healthy and fitting an employment as we might otherwise provide for him. It is not enough to find men absolute subsistence; we should think of the manner of life which our demands necessitate; and endeavour, as far as may be, to make all our needs such as may, in the supply of them, raise, as well as feed, the poor. It is far better to give work which is above the men, than to educate the men to be above their work. It may be doubted, for instance, whether the habits of luxury, which necessitate a large train of men servants, be a wholesome form of expenditure; and more, whether the pursuits which have a tendency to enlarge the class of the jockey and the groom be a philanthropic form of mental occupation. So again, consider the large number of men whose lives are employed by civilized nations in cutting facets upon jewels. There is much dexterity of hand, patience, and ingenuity thus bestowed, which are simply burned out m the blaze of the tiara, without, so far as I see, bestowing any pleasure upon those who wear or who behold, at all compensatory for the loss of life and mental power which are involved in the employment of the workman. He would be far more healthily and happily sustained by being set to carve stone; certain qualities of his mind, for which there is no room in his present occupation, would develop themselves in the nobler; and I believe that most women would, in the end, prefer the pleasure of having built a church, or contributed to the adornment of a cathedral, to the pride of bearing a certain quantity of adamant on their foreheads.

X. I could pursue this subject willingly, but I have some strange notions about it which it is perhaps wiser not loosely to set down. I content myself with finally reasserting, what has been throughout the burden of the preceding pages, that whatever rank, or whatever importance, may be attributed or attached to their immediate subject, there is at least some value in the analogies with which its pursuit has presented us, and some instruction in the frequent reference of its commonest necessities to the mighty laws, in the sense and scope of which all men are Builders, whom every hour sees laying the stubble or the stone.

I have paused, not once nor twice, as I wrote, and often have checked the course of what might otherwise have been importunate persuasion, as the thought has crossed me, how soon all Architecture may be vain, except that which is not made with hands. There is something ominous in the light which has enabled us to look back with disdain upon the ages among whose lovely vestiges we have been wandering. I could smile when I hear the hopeful exultation of many, at the new reach of worldly science, and vigour of worldly effort; as if we were again at the beginning of days. There is thunder on the horizon as well as dawn. The sun was risen upon the earth when Lot entered into Zoar.

1. 16. p. 209. 'In one of the noblest poems': Coleridge's Ode to France:

   Ye Clouds! that far above me float and pause,
   Whose pathless march no mortal may control!
   Ye Ocean Waves! that, wheresoe'er ye roll,
   Yield homage only to eternal laws!
   Ye Woods! that listen to the night-birds singing,
   Midway the smooth and perilous slope reclined,
   Save when your own imperious branches swinging,
   Have made a solemn music of the wind!
   Where, like a man beloved of God,
   Through glooms, which never woodman trod,
   How oft, pursuing fancies holy,
   My moonlight way o'er flowering weeds I wound,
   Inspired, beyond the guess of folly,
   By each rude shape and wild unconquerable sound!
   O ye loud Waves! and O ye Forests high!
   And O ye Clouds that far above me soared!
   Thou rising Sun I thou blue rejoicing Sky!
   Yea, every thing that is and will be free!
   Bear witness for me, wheresoe' er ye be,
   With what deep worship I have still adored
   The spirit of divinest Liberty.

   Noble verse, but erring thought: contrast George Herbert:

   Slight those who say amidst their sickly healths.
   Thou livest by rule. What doth not so but man?
   Houses are built by rule, and Commonwealths.
   Entice the trusty sun, if that you can.
   From his ecliptic line; beckon the sky.
   Who lives by rule, then, keeps good company.
   
   Who keeps no guard upon himself is slack.
   And rots to nothing at the next great thaw;
   Man is a shop of rules: a well-truss'd pack
   Whose every parcel underwrites a law.
   Lose not thyself, nor give thy humours way;
   God gave them to thee under lock and key.
