Text: […] Alexandi Gwagnini. – [Kraków:] 1578. – Lithvanie, fol. 18.
Details of this story borrowed from Wapowski (200,000 Turks killed) and Kromer (1.2 million troops Tamerlan). The mention of the killed princes comes from Kromer, but while Kromer mention two brothers Jagiello – Andrei and Dmitry-Korybut, in Alexander Guagnini between Dmitry and Korybut put a very expressive comma, and thus became the three killed.
