There is possibly a second significance to the "dom" of which Hugh Oldham, as a bishop, would have been very well aware. D.O.M. was and is a standard abbreviation for "Deo Optimo Maximo" meaning "To God, the Best and the Greatest", a phrase of dedication often required to be written by schoolboys before the Reformation and in Roman Catholic education since, at the head of a new piece of work, a practice continued into adult life by many as they committed a new undertaking into God's hands. This badge replaced the original one when the school colours changed from red, black and yellow to dark and light blue to reflect its connection with the universities of Oxford and Cambridge.
