Gonzalvo, Martin a Spanish religious impostor of the 14th century, was born at Cuenta, and called himself the archangel Michael, to whom God had reserved the place of Lucifer, and who would some day fight against antichrist. The Inquisition burned him, but his disciple, Nicolas de Calabrois, sought to represent him after his death as the Son of God, and preached that the Holy Spirit would become incarnate, and that at the day of judgment Gonzalvo would deliver by his prayers all the condemned. De Calabrois also perished in the flames. See Hoefer, Nouv. Biog. Generale, s.v.
