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).
