A Friar Minor and reformer, born at Valladolid, 1390; died at Aguilera, 30 March, 1456. His parents were of noble birth and conspicuous for their wealth and virtue. Having lost his father in his early youth, he was piously educated by his mother. At the age of ten years Peter begged to be admitted into the Seraphic Order, which favour was granted him three years afterwards in the convent of his native town. In 1404 he became one of the first disciples of Peter de Villacreces, who in 1397 had introduced into Spain the reform of the Observance of which he became one of the most zealous propagators. In the newly-founded convent at Aguilera Peter found the life of solitude, prayer, and eminent poverty, which had always been the greatest object of his desire. In 1415 he became superior of the convent at Aguilera and, on the death of Peter de Villacreces (1422), also of that at Tribulos or del Abroyo. He observed nine Lents, fasting on bread and water, and was endowed with the gift of miracles and prophecy and of every virtue. When his body was exhumed thirty-six years after his death, at the instance of Isabella the Catholic, it was found incorrupt and placed in a more precious tomb. He was beatified by Innocent XI, 11 March, 1684, and canonized by Benedict XIV, 29 June, 1746. His feast is celebrated 13 May, the day of the translation of his body. In art he is represented with flames bursting from his heart. - Source: www.newadvent.org
