Francisco de Goya
The Apparition of St. Isidore to King Ferdinand III Before the Walls of Seville

Oil on canvas

According to literature distributed by the Cathedral of Seville the main mosque of Islamic Seville was built on the site of earlier "public Roman and Visigoth buildings." This painting relies on the assumption that one of those buildings was a church dedicated to St. Isidore of Seville. After Ferdinand III reconquered Seville in 1248 the mosque was rededicated as the city's cathedral. This event was celebrated each year by a liturgy in which it was claimed that Isidore had appeared to Ferdinand in a vision and urged him to retake the church, which had been "profaned by the infidels for so many centuries."
