- The arms were adopted by the University around 1400 and are also reported as recorded or confirmed in connection with the 1574 visitation of Oxford. The 1574 confirmation point should be checked against the surviving College of Arms visitation material before being treated as a primary grant reference.

Notes / sources
The University’s present legend was in at least occasional use by the second half of the sixteenth century. Earlier legends associated with the same armorial design include Sapientiae et Felicitatis and the paired phrases Veritas Liberabit and Bonitas Regnabit. The number of book clasps was not originally fixed; seven clasps became a conventional later form.
