The name of Aretinus has been assumed by five
or six natives of Arezzo in Tuscany, of whom the most famous
and the most worthless lived in the xvith century.
Leonardus Brunus Aretinus, the disciple of Chrysoloras, was
a linguist, an orator, and an historian, the secretary of
four successive popes, and the chancellor of the republic of
Florence, where he died A.D. 1444, at the age of
seventy-five (Fabric. Bibliot. Medii Aevi, tom. i. p. 190
etc. Tiraboschi, tom. vii. p. 33 - 38)
