Sixtus IV issued the 1478 bull 'Exigit sincerae devotionis' that let Ferdinand and Isabella appoint inquisitors in Castile. He later voiced concern that the Spanish Inquisition was acting harshly and driven by greed rather than faith, but the crown ignored his objections. He is also remembered for building the Sistine Chapel, which bears his name.
