Born in the province of Valencia, Spain, Vincent Ferrer (1350 – 1419) joined the Dominican friars in 1367. In Spain, France, and elsewhere he drew huge crowds among Jews and Muslims as well as Christians as he warned of the evils of the time and preached the need for penance and church reform. A significant figure in ending the Western schism, he worked tirelessly for peace and unity within the church. Vincent is depicted holding the Book of Revelation, its key theme inscribed in Latin: “Timete Deum et date illi honorem quia venit hora iudicii eius” (“Fear God and give honor to him for the hour of judgement is coming”). The flame above his head symbolizes the Holy Spirit’s call to preach the Gospel. Vincent is known as a preacher of the Apocalypse, represented by the trumpet, according to Revelation: “At the time when you hear the seventh angel blow his trumpet, the mysterious plan of God shall be fulfilled.”
