Triptych of the Thronum Gratiae
by NARDO DI CIONE, Tempera on wood, 295 x 212 cm
The triptych depicts the Thronum Gratiae (Throne of Grace) in the centre and and Sts Romuald and John the Evangelist at the sides.
The Thronum Gratiae traditionally shows God the Father seated on a throne, with his legs slightly apart, holding the arms of the cross of Jesus in front of him in his hands, while the dove of the Holy Spirit flies over them (or between them).
