Some strangeness in the proportion

There is no excellent beauty that hath not some strangeness in the proportion. A man cannot tell whether Apelles or Albert Dürer were the more trifler; whereof the one would make a personage by geometrical proportions; the other by taking the best parts out of divers faces to make one excellent. Such personages, I think, would please nobody but the painter that made them. Not but I think a painter may make a better face than ever was; but he must do it by a kind of felicity (as a musician that maketh an excellent air in music), and not by rule.

—Francis Bacon
