The Cross of Cong
The Cross of Cong is one of the greatest treasures of the era. It was made to enshrine a portion of the True Cross acquired in AD 1122 by Toirrdelbach Ua Conchobair, High King of Ireland. An inscription records the names of Ua Conchobair, two high-ranking clerics and the craftsmen who made it.
The cross is made of oak covered with plain sheets of bronze. Panels decorated with animal interlace overlay these plain sheets, The relic, now missing, would have been visible behind the rock crystal at the centre of the cross-arms. A staff could be inserted at the base to enable the cross to be carried in procession. The shape of the cross-arms recalls the Tully Lough Cross, made almost four centuries earlier, but the decoration is in the late Scandinavian Urnes style. The glass and enamel studs are characteristic of Irish Romanesque metalwork.
