According to Prudencio de Sandoval's "Historia de los reyes de Castilla y León" (1615), Ferdinand II of Aragon gave a sword identified as Tizona to Pedro de Peralta y Ezpeleta, first Count of Santisteban of Lerín (also cited as Antonio Carrillo de Peralta, 2nd Marqués de Falces), for services rendered in the negotiations that led to his marriage with Isabel of Castile in 1469.
