Any one who leads this carefully cannot fail to see that it is not only that Dürer is not "desirous of laying down rules applicable to all cases," or even of "proposing a definite canon for the relative proportions of the human body," as Thausing indeed points out (p. 305, v. 11): but that he does not conceive the proportions he gives as even approximately capable of these functions; and considers it indeed the very nature and special use of a canon of proportions to be wilfully deviated from, pointing out that, though the deviations of which he is speaking are slight and subtle, they are not to be confused with the accidental ones that can but appear even in work done by mechanical processes. Rather they are such variation as a man "specially intendeth, and which standeth in his will;" and again, "such a difference as maketh a thing fair or foul;" for the use of these normal proportions is that they may enable an artist to deviate from the normal without the proportions he chooses having the air of monstrosities or mistakes or negligences. He does not insist that either of the scales he gives is the best that could be, even for this purpose, but that they are sufficiently good to be used; and he would have marvelled at the wonder that has been caused in innocent critical minds that in his own work he adhered to them so little. He never intended them to be adhered to.
V
It may be objected that Dürer certainly sometimes thought of a Canon of Proportion as a perfect rule, because he wrote on a MS. page as follows:--
Vitruvius, the ancient architect, whom the Romans employed upon great buildings, says that whosoever desires to build should study the perfection of the human figure, for in it are discovered the most secret mysteries of proportion. So, before I say anything about architecture, I will state how a well-formed man should be made, and then about a woman, a child and a horse. Any object may be proportioned out (literally, measured) in a similar way. Therefore, hear first of all what Vitruvius says about the human figure, which he learnt from the greatest masters, painters and founders, who were highly famed. They said that the human figure is as follows.
That the face from the chin upward to where the hair begins is the tenth part of a man, and that an out-stretched hand is the same length, &c.

And again in another place, as Sir Martin Conway points out, he gives a religious basis to this notion,[[85]] "the Creator fashioned men once for all as they must be, and I hold that the perfection of form and beauty is contained in the sum of all men." In an obvious sense these passages certainly run counter to those which I have quoted (pp. 285-207): but I would like to point out that these are dogmatic assertions about something that if it were true could never be proved by experience (see also pp. 64, 254), those former are Dürer's advice with a view to practice. Men frequently carry about a considerable amount of dogmatic opinion, which has so little connection with actual experience that it is never brought to the test without being noticeably incommoded by it. Yet it is not absolutely necessary to consider Dürer as inconsistent in regard to this matter, even to this degree.
The beauty of form which he held had been Adam's, and which was now parcelled out among his vast progeny in various amounts as a consequence of his fall--this beauty of form doubtless Dürer considered it part of an artist's business to recollect and reveal in his work. This beauty is an ideal, and his canon (or rather canons) were intended as means to help the artist to approach towards the realisation of that ideal. It is obvious also that a man occupied in comparing the proportions of those whom he considers to be exceptionally beautiful will develop and feed his power of imagining beautifully proportioned figures. It would be futile to deny that this is very much what took place in the evolution of Greek statues, or that such works are perhaps of all others the most central and satisfying to the human spirit. The sentences that precede that quoted by Sir Martin are Greek in tendency.
A good figure cannot be made without industry and care; it should therefore be well considered before it is begun, so that it be correctly made. For the lines of its form cannot be traced by compass or rule, but must be drawn by the hand from point to point, so that it is easy to go wrong in them. And for such figures great attention should be paid to human proportions, and all their kinds should be investigated. I hold that the more nearly and accurately a figure is made to resemble a man, so much the better the work will be. If the best parts chosen from many well-formed men are united in one figure, it will be worthy of praise. But some are of another opinion, and discuss how men ought to be made. I will not argue with them about that. I hold Nature for Master in such matters, and the fancy of men for delusion.
And then follows the passage quoted by Sir Martin Conway (see p. 289). It is obvious that, joined with the two preceding sentences, this passage can in no way be made to serve the academical practitioner, as it seems to when taken alone. In the same way, the sentence printed in italics in the above quotation, if isolated, would certainly seem to serve the scientific practitioners and their slavish realism, though in connection with those that follow this is no longer possible. Dürer regards nature as providing raw material for a creation which may not tally exactly with any individual natural object. This was the Greek artists' idea of the serviceableness of nature, as revealed both by their practice and by such traditions as that concerning Zeuxis and his five beautiful models for the figure of Venus. But Dürer does not confine the use of his canons even to this aim, but clearly perceived their utility in regard to quite other aims, as is shown by the passage beginning, "It is not to be wondered at," &c. (see p. 286), in which the imagination of figures not merely intended to embody beautiful or newly assorted proportions is clearly considered; and if we review Dürer's actual work we shall see how much oftener he created figures for picturesque or dramatic effect than he did to embody beautiful proportions in them, though he evidently also considered the last purpose as of the first importance, as we see when he goes on to say:
