These are the arms of Beaufort, since it has supporters and the College has no legitimised arms. The college arms are shared with St Johns and when Robert Cooke (d 1592), Clarenceux King of Arms made an Heraldic Visitation to Cambridge in 1575 he confirmed the arms of most of the colleges. Curiously he omitted to do so for either Christ's or John's. To have confirmed the right of one college would have meant granting a different version the another. As he himself was a graduate of St John's perhaps he could not bring himself to concede the arms of Beaufort to Christ's, being the senior college, knowing his own college would thereby be denied the use of them. St John's should have had the ams of John Fisher.
