The Irish Coat of arms is described as "a harp or, stringed argent, on a field
azure." The harp has been used in the coat of arms of Ireland since medieval
times. It is depicted alongside the coats of arms of a dozen or more medieval
European kingdoms on a single folio of the Wijnbergen roll of arms compiled
about 1270. The harp is found on the banners of the Irish brigades, which were
formed in the armies of continental European countries during the seventeenth
and eighteenth centuries.
The harp today is used as the symbol of the Irish
State. It is found in the seals of the President, Taoiseach, T�naiste and
Government Ministers and is used on the back of Irish coins including new euro
coins minted in Ireland.
The Presidential Standard is a blue flag with the
heraldic harp. The model for the artistic representation of the heraldic harp
is the 14th century harp now preserved in the Museum of Trinity College Dublin,
popularly known as the Brian Boru harp.
