Saint John the Evangelist surrounded by Seven Angels (Main View (.recto) / book image source)

Pictured at center is Saint John the Evangelist, believed to be the author of the fourth Gospel and the Book of Revelations (also known as the Apocalypse, or his visions of the end of the world.) He is surrounded by angels representing the Seven Churches meant to receive his prophetic writings.

The artist's skill is notable in the delicate modeling of the body and the elegance of his features, which have a remarkable sculptural quality. The composition is strong in part because of the carefully balanced sense of color and geometry of the design. Rather than appearing to hold still, each of the seven angels sways and gestures differently, creating a sense of animated movement throughout. The tradition of German Gothic illumination is evident in the subtle and restrained palette coupled with the elegantly draped figures.
