The plain of Muirthemne · Co. Louth
The plain where Cú Chulainn grew up.
The low country of north Louth, around Dundalk. Here, the Táin says, the boy Sétanta was reared by his mother and father, and from here he set out alone for Emain Macha. When he took the place of Culann’s hound, he promised to guard it so that no herd or beast would be taken out of it. When Lady Gregory retold his life in 1902, she named her book after this plain.
