This stone head with three faces was found in Corleck, Cavan, and is known as the Corleck Head. Art experts date it to the 1st or 2nd Century CE (Iron Age). It now resides in the National Museum of Ireland – Archaeology.
Celtic myth has a long history of triplism, or themes of three. This can be seen in mythology with gods like Lugh, who has three names and forms, and in art with the triskele, a Celtic pre-Christian design.
