The image of Cú Chulainn is invoked by both Irish nationalists and Ulster unionists . The Gaelic revival fed into the Irish revolutionary period , with elements of Irish mythology adopted in nationalist symbolism . In St. Enda 's School , run by Patrick Pearse , there was a stained-glass panel of Cú Chulainn . A bronze sculpture of the dead Cú Chulainn by Oliver Sheppard stands in the Dublin General Post Office ( GPO ) in commemoration of the Easter Rising of 1916 . The statue 's image is reproduced on the obverse of 1916 Medal awarded to republican veterans of the rising , the Military Star of the Irish Defence Forces , and the commemorative ten shilling coin issued in 1966 for the rising 's 50th anniversary
