This detail of The Sixth Angel Delivers the Four Angels That Had Been Enchained in the Euphrates depicts an episode described in the book of Revelation. The work was painted in Spain in the late 12th century to illustrate Beatus of Liébana's Commentaria In Apocalypsin, which was written in the 8th century.
I included the close-up simply because the similarity between the angels' wings and the fishes' scales interested me.
