Several notes in the upper margin of the pages serve as captions for the illustrations of the martyrdom of St. George, but some of the explanations and the images don't match. Probably the captions were written first and the illustrations done later.
Text in black ink. Beginning of each prayer and anaphora, instructions for the priests and deacons, and also the order of pointing and benediction over the Host (bread) and the cup (wine) are in red ink.
Parts of one quire (including pp. 313 on the Praises of Mary) are inserted incorrectly in the manuscript. They appear earlier than they should. This misplacement probably happened in Ethiopia when the very old manuscript was rebound.
