[Footnote 75: Leonardus Brunus Aretinus, one of the revivers
of classic learning in Italy, who, after serving many years
as secretary in the Roman court, retired to the honorable
office of chancellor of the republic of Florence, (Fabric.
Bibliot. Medii Aevi, tom. i. p. 290.) Lenfant has given the
version of this curious epistle, (Concile de Pise, tom. i.
p. 192 - 195.)]
