For Coluccio Salutati, Chancellor of Florence from 1375 to 1406 and the acknowledged leader of Italian humanism after the deaths of Petrarca and Boccaccio, Virgil occupied a special place as “princeps poetarum.” One way to approach the question is to examine the marginalia themselves to determine whether the kinds of information they contain and the handwriting in which they are written can be dated; the earlier the marginalia, the more probable the 1355 purchase date becomes. For purposes of analysis, it will be easiest to separate Salutati’s notes into categories. The presence of meter and figurative language, however, is not the sole distinguishing feature of poetic language. Through anagogy, literature can supplement the Bible as a source for Christian teaching. There are occasional suggestions of an aesthetic stance in early humanist literature.
