Fra Angelico (born Guido di Pietro; c. 1395 – February 18, 1455) was an Early Italian Renaissance painter described by Vasari in his Lives of the Artists as having "a rare and perfect talent".
He was known to contemporaries as Fra Giovanni da Fiesole (Brother John of Fiesole) and Fra Giovanni Angelico (Angelic Brother John). In modern Italian he is called il Beato Angelico (Blessed Angelic One); the common English name Fra Angelico means "Angelic Brother."
In 1982 Pope John Paul II conferred beatification, in recognition of the holiness of his life, thereby making the title of "Blessed" official. Fiesole is sometimes misinterpreted as being part of his formal name, but it was merely the name of the town where he took his vows as a Dominican friar, and was used by contemporaries to separate him from other Fra Giovannis. He is listed in the Roman Martyrology as Beatus Ioannes Faesulanus, cognomento Angelicus—"Blessed Giovanni of Fiesole, nicknamed Angelico".
