Leander of Seville
bishop of Seville
Feast: 13 March (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Leander, born at Carthage about 534, was the brother of Sts Isidore, Fulgentius and Florentina. He became a monk and in 579 Bishop of Seville, where he founded a celebrated school of learning and orthodoxy.
He helped convert Prince Hermenegild, was exiled by the Arian King Leovigild, and after 589 did most to secure the religious unity and faith of Spain. He died at Seville on 13 March 600 or 601.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
A bishop who led Visigothic Spain from Arianism to the Catholic faith.
