. "Giacomo d'Angelo da Scarperia or Scarparia (Jacobus Angelus) was a Renaissance humanist, born in Florence. He hastened to Venice, when Manuel Chrysoloras had arrived as an envoy of Manuel Paleologus in 1393 and had stayed to teach Greek in Italy for the first time in seven centuries. He decided to return with Chrysoloras to Constantinople \u2014 the first Florentine to do so \u2014 in company with Guarino da Verona, to immerse himself in advanced Greek studies under Demetrios Kydones. Coluccio Salutati wrote to urge Giacomo to search the libraries there for texts especially of Homer, and for lexicons of the Greek language, with the result that Giacomo translated Ptolemy's Geographia into Latin in 1406: he dedicated it first to Pope Gregory IX, and then in 1409 rededicated it to Alexander V. He also brought new texts of Homer, Aristotle and Plato to the attention of western scholars."@en . . . "Giacomo da Scarperia"@en . . .
