(Chapter 4) Footnote 25:
Vesalius’ source here appears to be Galen, De ossibus ad tirones 2.735.13. A ginglymus or hingelike joint is today distinguished from an enarthrosis or spheroid joint. Galen used ginglymus especially for the elbow joint, articulatio humero-ulnaris. The 1555 edition omits the reminder in this sentence (a favorite Vesalian theme, on which see note 51 in Vesalius’ Preface) that the Greeks taught their sons dissection.
