(Chapter 33) Footnote 34:
On Aristotle’s errors regarding leg anatomy in animals, see Ch. 23 n. 31 and Ch. 31 n. 23. The marginal note cites Aristotle Progression of Animals (where see 704a17-b6), and Book 3 of Galen De usu partium, where see 3.180.10 ff., tr. May 1968 pp. 159-160. Vesalius’ words here regarding Aristotle are especially interesting as doctors trained at Padua in the 16th century were required to swear an oath to defend Aristotle’s authority. See Anthony Grafton in The New York Review of Books XLIV.6 (4/10/97), p. 57.
