Galvam (or Galvao), Joio, Count of Arganil
Galvam (or Galvao), Joio, count of Arganil was a warlike Portuguese prelate, born at Evora in the 15th century. He was the son of Ruy Galvao, secretary of Alfonso V, and succeeded his father. He became prior of the convent of the Augustines, and in 1451 accompanied princess Leonora, as she went to be married to the emperor Frederick III. On his return, in 1461, he became bishop of Coimbra. Alfonso V sent him ten years later to Africa. At Arzilla and Tangier he fought so valiantly that the king conferred upon him the title of count of Arganil, which title ever afterwards belonged to the bishop of Coimbra. The archbishopric of Braga being vacant, Galvao was called to it by Sixtus IV in 1480. He died August 5, 1485, at a very advanced age. He left in manuscript, Jornada da Emperatriz Dona Leonor.
