Leath Cuinn (Conn's Half) and Leath Moga (Mug's half) are legendary ancient divisions of Ireland, respectively north and south of a line corresponding to the #EskerRiada running east–west from #DublinBay to #GalwayBay. The eponymous Conn and Mug were #ConnCétchathach (Conn of the Hundred Battles) and #ÉoganMór #MugNuadat (the Servant of Nuada), whose armies in 123 AD fought the battle of #MagLena (the Plain of Lena, in what is now #CountyOffaly between #Tullamore and #Durrow).
