The earliest people to inhabit the Dingle (Corca Dhuibhne) and Iveragh (Uíbh Ráthach) peninsulas were the Corcu Duibne. The oldest reference to them occurs in a number of ogham inscriptions of 5th century date, in which they are described as Muccoi Dovinia, 'the followers [or sons] of [the goddess] Dovinia'. Dovinia was the female ancestor divinity or goddess of this people. Later, when Christianity had taken a firmer hold, Dovinia was written out of history and the Corcu Duibne instead made to descend from a male ancestor, the fictional Corc Duibne. A good example of one of these 'Dovinia' ogham stones is the one at Ballinrannig, overlooking Smerwick harbour. Others can be found elsewhere on the peninsula as well as in Iveragh.
