England to have been lost sight of in borrowing our methods from Germany. They hold themselves at liberty to, and usually do, make all their charges on the shield face to the centre. This is never done in England, where all face to the dexter. It seems therefore to me an anomaly to apply one rule to the shield and another to the helmet, and personally I prefer that both helmets and all charges should face the dexter.
In British heraldry (and in fact the rule is universal) no woman other than a reigning Sovereign is permitted to surmount her arms by a helmet. Woodward states that "Many writers have denied the right of ecclesiastics (and, of course, of women) to the use of helmet and crest. Spener, the great German herald, defends their use by ecclesiastics, and says that, in Germany at any rate, universal custom is opposed to the restriction. There the prelates, abbots, and abbesses, who held princely fiefs by military tenure, naturally retained the full knightly insignia."
In official English heraldry, there is a certain amount of confirmation and a certain amount of contradiction of this supposed rule which denies a helmet to an ecclesiastic. A grant of arms to a clergyman at the present day, and at all times previously, after the granting of crests had become usual, contains the grant of the crest and the emblazonment shows the helmet. But the grant of arms to a bishop is different. The emblazonment of the arms is surmounted by a mitre, and the crest is depicted in the body of the patent away from and distinct from the emblazonment proper in the margin. But the fact that a crest is granted proves that there is not any disability inherent in the ecclesiastic which debars him from the possession of the helmet and crest, and the rule which must be deduced, and which really is the definite and accepted rule, is that a mitre cannot be displayed together with a helmet or crest. It must be one or other, and as the mitre is indicative of the higher rank, it is the crest and helmet which are discarded.
There are few rules in heraldry to which exceptions cannot be found, and there is a painting now preserved in the College of Arms, which depicts the arms of the Bishop of Durham surmounted by a helmet, that in its turn being surmounted by the mitre of episcopal rank. But the Bishopric of Durham was, in addition to its episcopal character, a temporal Palatinate, and the arms of the Bishops of that See therefore logically present many differences and exceptions from established heraldic rules.
The rules with regard to the use of helmets for the coats of arms of corporate bodies are somewhat vague and vary considerably. All counties, cities, and towns, and all corporate bodies to whom crests have been granted in England, have the ordinary closed profile helmet
