Federigo Ubaldini (1610 - 1657) was an Italian Dante and Petrarch scholar, secretary to Cardinal Francesco Barberini, and later secretary to the papal consistory in Rome. He was born in Siena. He published a biography of Angelo Colocci and various notes on Renaissance poets.[1] He created annotations about the Divine Commedy.[2] In 1642, Federigo edited a publication of the work Il Tesoro by Brunetto Latini (c. 1220–1294), a guardian and teacher of Dante.
