Elionor de Villena, was born in Valencia, in the year 1430. Natural daughter of Enrique de Aragon and Castile (Enrique de Villena), related to the houses of Aragon and Castile. Orphaned at the age of four, she was raised in court by Queen Maria of Castile, wife of King Alfonso the Magnanimous and first cousin of Queen Isabella the Catholic. On 28 February 1445 she entered the monastery of the Holy Trinity, Franciscan Poor Clares, which had been founded by the Queen herself a year earlier, after the expulsion of the monks who occupied it. In 1463 she was appointed abbess and wrote in her work Vita Christi, one of the most important pieces of literature in the fifteenth century.
