After this I heard what seemed to be the loud voice of a great multitude in heaven ... And the twenty-four elders and the four living creatures fell down and worshiped God who is seated on the throne, saying, "Amen. Alleluia!" ... Then I fell down at his feet to worship him, but he said to me, "You must not do that! I am a fellow servant with you and your comrades who hold the testimony of Jesus. Worship God!" (Rev. 19:1-4, 10).
Christ is seated with His arms spread in blessing within a mandorla on a golden rainbow. Around Him are the four symbols of the evangelists. The calf of Luke and the lion of Mark are at his feet and each is holding a book. On each side an angel is sounding a trumpet.
In the lower panel, two groups of elders bow in worship to Christ. At the front John falls down in praise before the angel.
From the 11th century Bamberg Apocalypse.
