This paper shows some annotations of the Florentine notary and poet Domenico Silvestri (1335 ca.-1411 ca.) in a famous Boccaccio’s autograph, MS. Zibaldone Magliabechiano (Firenze, Bibl. Nazionale Centrale, Banco Rari, 50), a large miscellany written in ‘mercantesca’ around 1355. Silvestri was looking for information about geographical subjects, in order to elaborate his important encyclopedia De insulis, an alphabetical catalog of all the islands in the world. In particular he read and put some notabilia on Boccaccio’s De Canaria, describing Canary Islands. Silvestri also annotated some extracts of the Chronologia magna of Paulinus Venetus (1270-1344 ca.), quoting this work in the De insulis.
