Dating from the last quarter of the 8th or first quarter of the 9th century, the Harley Prayer Book includes an annotation symbol resembling a rune-like dotted ‘Y’ added around the time of the book’s creation. The same symbol appears in the Royal Prayer Book, pointing to likely shared provenance of these two manuscripts.[1]
All of the prayers are copied in an insularminuscule script, in ink, with small initials added in brown ink, and some letters highlighted or heightened by addition of red, green, or yellow, or some combination of the three.[1]
