Therefore the force, secrecy and power, in what maner the sacred names of spirits are truly and rightly found out, consisteth in the disposing of the vowels, which do make the name of a spirit, and wherewith is constituted the true name and right word. Now this art is thus perfected and brought to pass: first, we are to take heed of the placing the vowels of the letters, which are found by the calculation of the celestial figure, to finde the names of the spirits of the second order, Presidents and Governours. And this in the good spirits, is thus brought to effect, by considering the starts which do constitute and make the letters, and by placing them according to their order: first, let the degree of the eleventh House be subtracted from the degree of that star which is first in order; and that which remaineth thereof, let it be projected from the degree of the ascendant, and where that number endeth, there is part of the vowel of the first letter: begin therefore to calculate the vowels of these letters, according to their number and order; and the vowel which falleth in the place of the star, which is first in order, the same vowel is attributed to the first letter. Then afterwards thou shalt finde the part of the second letter, by subtracting the degree of a star which is the second in order from the first star; and that which remaineth, cast from the ascendant. And this is the part from which thou shalt begin the calculation of the vowels; and that vowel which falleth upon the second star, the same is the vowel of the second letter. And so consequently maist thou search out the vowels of the following letters alwaies, by substracting the degree of the following star; from the degree of the star next preceding and going before. And so also all calculations and numerations in the names of the good spirits, ought to be made according to the succession of the signes. And in calculating the names of the evil spirits, where in the names of the good spirits is taken the degree of the eleventh House, in these ought to be taken the degree of the twelfth House. And all numerations and calculations may be made with the succession of the signes, by taking the beginning from the degree
