Anniversary of the Papal Bull

Tuesday 28 August 2012

It was on 28 August 1413 that the six bulls of Pope Benedict XIII issued from Peñiscola - confirming the privileges of the University of St Andrews. Only one of the six bulls survives, and is still held by the University in its archives.
Today a cast of Pope Benedict’s skull sits on display in the University Museum, a lasting imprint of the man who allowed the University the power to grant degrees.
Benedict XIII was known affectionately as Papa Luna, and his crescent moon still tops the University’s coat of arms.
Visitors to MUSA can explore the events that led up to the signing of the bull and the early years of the University that resulted through items from the medieval period. MUSA is open 10am-5pm Monday-Saturday and noon to 4pm on Sundays.
