Trinity College harp

The Trinity College harp, also known as "Brian Boru's harp", is a medieval musical instrument on display in the long room at Trinity College Dublin in Ireland. It is an early Irish harp or wire-strung cláirseach. It is dated to the 14th or 15th century and, along with the Queen Mary Harp and the Lamont Harp, is the oldest of three surviving medieval harps from the region. The harp was used as a model for the coat of arms of Ireland and for the trade-mark of Guinness stout.
