 In Spain this belief was combined with Joachimism and prophecies attributed to Isidore of Seville to produce belief in a future Spanish emperor, variously named "el Encubierto" (the Hidden One), "el Murciélago" (the Bat) or "el Nuevo David" (the New David).It was thought that each succeeding Spanish king might be the hidden one who would defeat the Antichrist and begin the conquest of Islamdom from Granada to Mecca.These expectations reached a fever pitch during the reign of Ferdinand II of Aragon between 1480 and 1513.
