Battle Scene, From Book of Maccabees I, second half of 9th–early 10th century.
Ink on parchment

Currently on display at the Metropolitan Museum of Art, New York
This is part of Pen and Parchment: Drawing in the Middle Ages, an exhibition of ink drawings currently at the Metropolitcan Museum of Art. I've looked through the images on display at the exhibition blog, and read a glowing review by Jed Perl in The New Republic, and man do I want to see it in person. Probably not going to happen, alas.
Incidentally, there's a high resolution version of this work here. It's well worth checking out.
