Monastery of Santa María del Parral

Monastery of Saint Mary of Parral (Spanish: Monasterio de Santa María del Parral) is a Roman Catholic monastery of the enclosed monks of the Order of Saint Jerome just outside the walls of Segovia, Spain.

Despite a generally irreligious life, Henry IV maintained connections with the Hieronymites and was buried in the sister-house of Monastery of Santa María de Guadalupe.

The Fountain of Grace (The Triumph of the Church over the Synagogue), has attracted interest because of its presumed connection to the artist Jan van Eyck.

Listed in the Convent's Libero de Bercero (Vellum Book) as a gift of the King in 1454, it uses the same symbolic language and constructional forms as part of The Mystic Lamb polyptych in St Bavo's Cathedral, Ghent, Belgium.

Theories regarding its attribution have included the idea that it was rushed copy of a lost original, originally commissioned by Pope Eugene IV for a chapel in Brussels, possibly undertaken by Jan van Eyck during a diplomatic mission he undertook to the Iberian Peninsula in the 1430s.
