(Chapter 24) Footnote 25:
Lat. copia, the regular rhetorical term for command of the resources of eloquence. For the Humanists, this included a command of vocabulary that allowed an author to avoid excessive repetition of a word. Erasmus’ De duplici copia rerum ac verborum (first published in 1512 and often revised) was the standard textbook on this subject ca. 1530-33 when Vesalius was learning the refinements of Latin style at Louvain. See the English translation and notes by Betty I. Knott in Thompson 1978, 279-659, and Rix 1946. “It was perhaps in the Pedagogium Trilingue [at the University of Louvain] that Vesalius acquired his considerable fluency — as well as unfortunate verbosity — in Latin.” (C.D. O’Malley, AVB p. 33). Vesalius’ remarks about the lexical excesses of other writers may therefore strike an ironic note in the reader’s mind.
