Besides some valuable hints from Aeneas
Sylvius, which are diligently collected by Spondanus, our
best authorities are three historians of the xvth century,
Philippus Callimachus (de Rebus a Vladislao Polonorum atque
Hungarorum Rege gestis, libri iii. in Bel. Script. Rerum
Hungaricarum, tom. i. p. 433 -518), Bonfinius (decad. iii.
l. v. p. 460 - 467), and Chalcondyles (l. vii. p. 165 -
179). The two first were Italians, but they passed their
lives in Poland and Hungary (Fabric. Bibliot. Latin. Med.
et Infimae Aetatis, tom. i. p. 324. Vossius, de Hist.
Latin. l. iii. c. 8, 11. Bayle, Dictionnaire, BONFINIUS). A
small tract of Faelix Petancius, chancellor of Segnia (ad
calcem Cuspinian. de Caesaribus, p. 716 - 722), represents
the theatre of the war in the xvth century.
