Reading edition
Muratori Annali, tom. ix. p. 456. It may be mentioned as a striking instance of the liberty which was granted by personages of the most exalted eminence to scholars of celebrity in the fifteenth century, that Poggio at various times addressed letters to his patron, cardinal Beaufort, to prince John Corrinus, Waiwode of Hungary, to the duke of Viseo, brother to Edward, king of Portugal, and also to Alfonso, king of Naples, exhorting them to active exertions against the Turks, who at this time threatened to overrun some of the finest countries of Europe. These letters still exist in the Riccardi MS. Ton. Tr. tom. ii. p. 140.
