In the left panel the Virgin is shown in a pose of adoration.
The central panel represents Christ of the Apocalypse as described in the New Testament (Revelation 1: 13). He has a golden girdle; his head and hair are 'as white as snow'; in his right hand he holds the seven stars and in his left the keys of death and hell. Originally he may have held a two-edged sword in his mouth.
On the right, John the Baptist holds a scroll with an inscription from the Old Testament (Isaiah 7: 14) 'Ecce virgo co(n)cipiet' (Behold a Virgin shall conceive). The scroll originally read 'Ecce agnus dei' (Behold the Lamb of God), the words usually associated with the Baptist.
