St. Malachy, an Irish archbishop born in 1094, reportedly was summoned to Rome by Pope Innocent II. While there, tradition holds that he had a vision in which details were revealed to him about all of the future popes. After he wrote the vision and gave it to the Pope, his document was filed in the Catholic Church archives and was left forgotten until it was discovered by Arnold de Wyon, a Benedictine historian, in 1590. In 1595, de Wyon published St. Malachy's vision in his Lignum Vitae.
