PSALM XCII (93), f. 54v.
In the center of the heavens the beardless, cross-nimbed Christ-Logos, holding a spear, shield (his 'strength,' verse 1) and two scrolls ('testimonia tua,' verse 5), is standing within a mandorla, amidst six angels holding bannered cross-staffs. Below Him is a large throne with a covering cast over it, flanked by two figures with books ('Thy throne is established of old,' verse 2). To the right and left is a seated river-god holding reeds and blowing a trumpet ('the floods have lifted up their voice,' verse 3). A stream issues from the jar upon which each of these river-gods is leaning and empties into a sea on either side of the lowest register. Boats filled with men are on the seas (verse 4). Between the two seas and beneath the throne of God is an 'orbis terrae' (verse 1) supported by two Atlantes, and inclosing a tabernacle with parted curtains exposing the altar and the hanging lamp (verse 5). Two groups of men praising the Lord flank the altar.
