The 'Brian Boru' harp of Trinity College Dublin is one of the most recognised harps in the world. Its iconic profile appears on Irish government documents and Euro coins, and is the model for the Guinness logo. Presumed to date to circa the 14th–15th centuries, it is also one of the oldest surviving early Irish harps, and one of very few extant examples of the instrument's earliest surviving, 'low-headed', form. This illustrated talk will introduce you to this important instrument, its form and craftsmanship, what is known of its history, and the historical context in which it was played.
