(Chapter 23) Footnote 34:

The “insufficiently anatomical” parts of Erasmus’ A)stragalismo/j sive Talorum lusu (Basel, 1529) are based on passages in Aristotle’s Historia Animalium (499b 20-31) and de Partibus Animalium (690a 5-27), and Pliny Nat. Hist. 11.106, 255. “From Aristotle and Pliny I’ve learned that human beings don’t have knucklebones [tali]. Only quadrupeds have them; not all quadrupeds, however, but very many of the cloven-hoofed ones, though only in their hind legs. . . . The bending that a man has in his arms, quadrupeds have in their hind legs. (I except the ape, a half-man.) Thus elbow is to arms what knee is to legs.” tr. Thompson 1965, pp. 434, 437. Latin edition: Erasmus, Opera Omnia (Amsterdam: North-Holland Publishing Co.) vol. I.3 (1972), pp. 620ff. lines 13-15, 113-115. Vesalius mentions this colloquy again in chapter 31 of the present book (see p. xxx and n. xx).
