- Eria: the old name for the small island outside Dublin Bay now known as Ireland's Eye was Eria's Island. Eria was a woman's name and this became confused with Erin, an Irish name for Ireland. The Vikings substituted the Old Norse word Ey (Island) and so the island became known as Erins Ey and ultimately Ireland's Eye
