here's a better shot of the document. source is here.
What is this document? According to the British Library blog: "A mid-12th century trilingual Greek, Latin and Arabic Psalter from Sicily illustrates an intricate propagandistic message. The manuscript contains the trilingual text in the ancient layout of three separate columns, but its function was probably much more than fulfilling the practical needs of a multilingual liturgical environment or serving as a textbook of an eccentric scholar. It was designed as a tool in the political propaganda of the Norman dynasty, ruling an essentially trilingual Sicily in the 12th century. Its threefold layout with one and the same text in Greek, Latin and Arabic testifies to a society in which multiple language groups had come together under a new Norman rule."
There are plenty of books and articles on the Arab period in Sicily -- I suggest having a look at Karla Mallette's The Kingdom of Sicily, 1100-1250: A Literary History (U Penn, 2005).
