According to legend, after being martyred, ravens protected St. Vincent's body from being devoured by vultures, until his followers could recover the body. His body was taken to what is now known as Cape St. Vincent; a shrine was erected over his grave, which continued to be guarded by flocks of ravens. In the time of Muslim rule in the Iberian Peninsula, the Arab geographer Al-Idrisi noted this constant guard by ravens, for which the place was named by him كنيسة الغراب Kanīsah al-Ghurāb (Church of the Raven). King Afonso I of Portugal (1139-1185) had the body of the saint exhumed in 1173 and brought it by ship to the Lisbon Cathedral. This transfer of the relics is depicted on the coat of arms of Lisbon.
