Commentary on the Apocalypse and commentary on the Book of Daniel
Purchased by J. Pierpont Morgan (1837-1913) in 1910
Apocalypse: Vial VI, Euphrates dried up (Revelation 16:12) -- Nimbed angel issuing from cloud, emptying vial upon River Euphrates; starred background.
And the sixth angel poured out his bowl upon the great river Euphrates. And its water dried up so that a way might be prepared for the kings from the rising of the sun. (Rev. 16:12)
Evidently insufficient space was left for the miniature, so the Euphrates flows from the vertical brown earth into the margin and in the direction of the large miniature on the opposite page (exhibited at the right), which continues the story. According to the commentary, the kings are saints who will be taken away by Christ.
