Sobreviveu a quatro séculos de Islão. Não sobreviveu aos cruzados.

Father Miguel Lopes Neto of the Diocese of Algarve reports that a Christian bishop was killed by Crusaders during the conquest of Lisbon in 1147. Neto states the bishop belonged to a Christian community and clergy that had survived four centuries of Islamic rule by paying the jizya tax.

The Crusaders, who were traveling toward the Holy Land, reached Lisbon following a contract negotiated by King Afonso Henriques and the Bishop of Porto. This agreement allowed the foreign soldiers to keep the spoils and ransoms while the king took the city. While Lisbon surrendered in October after a months-long siege under promises of safety, Neto reports that the city was looted and many people were killed, including the elderly bishop.
