Discursos de la guerra del Peloponeso. Versión aragonesa de la "Historia de la Guerra del Peloponeso" patrocinada por Juan Fernández de Heredia

Juan Fernández de Heredia (ca. 1310-1396), man of letters and knight, Grand Master of the Knights Hospitaller from 1377. A prominent figure within the Crown of Aragon and at Avignon's papal court, Heredia combined military leadership – he fought in the Aegean and was captured by Ottoman forces – with significant diplomatic influence in both Aragonese and papal affairs. Heredia founded a scriptorium in Avignon that produced major historiographical projects in the Aragonese vernacular, including Plutarch's Lives, Zonaras' Byzantine Epitome, and notably a partial translation of Thucydides. Spending his final years in Avignon under antipope Clement VII, Heredia continued overseeing this cultural production until his death in 1396. Treccani
