Dominus illuminatio mea is the motto of the University of Oxford and the opening words of Psalm 27, meaning The Lord is my light. It has been in use at least since the second half of the sixteenth century, and it appears on the University's arms. It is also used by St Leo's College, University of Queensland and by Drew University in Madison, NJ.
