The gold caisson ceiling has four large paintings by Andrea dell'Asta. They depict the flagellation of Saint Andrew, the miracle of Manna, the crucifixion of Saint Andrew and the Saint on the cross. From the left hand nave there is a flight of stairs which leads to the crypt. These stairs were built in 1203 for Cardinal Pietro Capuano, who, on 18 May 1208, brought Saint Andrew's remains to the cathedral from Constantinople.[citation needed]
