Severus of Menorca was a bishop on the island of Menorca in the early 5th century. According to the Epistula Severi Severus was at the forefront of a mass conversion where most of the Jewish population on the island converted to Christianity in 418 C.E. The Epistula Severi explains that the relationship between the Jews and the Christians on the island grew tense when relics of St. Stephen arrived on the island approximately a year before the conversion began. It took eight days to convert the Jewish population to Christianity and, in that time, the synagogue on the island was burnt to the ground and 540 Jews were converted.
