It is well written in a clear round hand with red or red and blue capitals. One floriated initial begins the Introit for Christmas Day. The colouring, blue, red, green, and pale yellow, is somewhat crude and the workmanship also, but the result is effective. The music is in neums. One floriated initial begins the Introit for Christmas Day.
