The Dutch humanist Desiderius Erasmus, in his 1512 textbook De Copia, stressed the connection between memory and reading. He urged students to annotate their books, using “an appropriate little sign” to mark “occurrences of striking words, archaic or novel diction, brilliant flashes of style, adages, examples, and pithy remarks worth memorizing.” He also suggested that every student and teacher keep a notebook, organized by subject, “so that whenever he lights on anything worth noting down, he may write it in the appropriate section.” Transcribing the excerpts in longhand, and rehearsing them regularly, would help ensure that they remained fixed in the mind. The passages were to be viewed as “kinds of flowers,” which, plucked from the pages of books, could be preserved in the pages of memory.
