Chrysoloras
Chrysoloras, Manuel, born at Constantinople about 1355, of high family, was early employed by John Palaeologus to implore the aid of the Christian princes against the Turks. In 1395 he was invited by the Florentines to teach Greek in that city. He afterwards visited Pavia, Milan, and Venice, and then, on the invitation of Aretino, secretary to Pope Gregory XII., settled in Rome. He was sent by the pontiff in 1413 to arrange with the Emperor Sigismund the assembling of the council of Constance, and on his way to attend the first meeting in 1415 he died suddenly. His Erotemata, a Greek grammar, was long in use, but only one of his other works has been printed.
