Brooch of an Edward III noble

A brooch cast from a mould of a Edward III Treaty period noble. It was found near the Oxford Colleges with a date of production only a few years after the St Scolastica Day riots, which was sparked by some students complaining about the quality of wine in an Inn. In the aftermath, Edward III came down on the side of the university. Hence, it is suggested that this brooch may have been worn by a professor of student.
