Castletimon Ogham Stone (CIIC 047) is an ogham stone and National Monument located near Brittas Bay, County Wicklow, Ireland.[1]
Castletimon Ogham Stone lies prone by the roadside 2.2km (01.4miles) west of Ballynacarrig beach, which opens onto Brittas Bay. Potter's River flows 260m (850feet) to the south.[2]
Castletimon Ogham Stone was carved c. AD 350–550, and was rediscovered in 1854.
Local legend claims that the Ogham stone was once picked up by the Castletimon Giant and thrown down the hill; the scratches on it were left by his finger nails. Another says that a local man took the Ogham stone to use as a hob stone. The Aos Sí (fairies) got angry and made his cutlery dance and jiggle. After a week of this he returned the stone to its place.[3]
Castletimon Ogham Stone measures 150 × 48 × 20 cm and has Ogham carvings incised on one edge. (NETACARI NETA CAGI, perhaps "Netacari, nephew of Cagi"). Variant readings include NETACARI NETACAMI, QEVASARI QEVASAGI or NETACARI SETACAGI.[4]
