In short: Francesc Eiximenis was a powerhouse of medieval thought, advising kings, queens, and popes while shaping the political and religious landscape of Valencia. His prolific writings were so widely read that his incunabula editions dwarfed those of literary giants, marking him as a central figure in the intellectual history of Catalonia.

Born around 1330, likely in Girona, Francesc Eiximenis joined the Franciscans early in life. His intellectual formation was deeply rooted in the traditions of the University of Oxford and the University of Paris, where he absorbed the ideas of prominent British thinkers like William of Ockham and John Duns Scotus. Though he initially lacked the formal title of Doctor in Theology, he secured it at the University of Toulouse in 1374 with royal backing, setting the stage for a career defined by immense political and literary influence.

Settling in Valencia in 1382, Eiximenis became a tireless public figure. He served as a consultant to the city's ruling bodies, organized relief efforts during the social unrest of 1391, and advised King Martin I on the Western Schism. His political reach was vast; he even proposed a unified school system in 1399, a precursor to the University of Valencia. By 1408, his stature was such that Pope Benedict XIII appointed him Patriarch of Jerusalem and administrator of the diocese of Elna, shortly before his death in 1409.

Eiximenis' literary output was staggering, spanning theological treatises, political advice, and moral guides. His massive project, Lo Crestià, aimed to provide a comprehensive theological framework in popular language. His influence transcended borders; his works were translated into Spanish, French, and Flemish, and his books were often the first printed in new territories, such as the 1478 Geneva edition of his Book of Angels. Today, over 200 surviving manuscripts testify to his enduring status as a cornerstone of medieval Catalan culture.
