Celtchar

Celtchar (or Celtchair), son of Uthechar or Uthidir, is a character from the Ulster Cycle of Irish Mythology. In Scéla Mucce Maic Dathó ("The Tale of Mac Dathó's Pig") he is described as "a grey, tall, very terrible hero of Ulster". When he challenges Cet mac Mágach for the champion's portion, Cet counters that he once emasculated Celtchar with a spear at Celtchar's own house. He lives in Dún Lethglaise, also known as the Mound of Down (Irish Dún), or Rathkeltair (Irish Ráth Celtchair or Celtchar's Fort) in Downpatrick, County Down. His wife is Findmór of Dún Sobairche (Dunseverick, County Antrim). He wields a spear or lance, the Lúin Cheltchair, whose lust for blood is so great it has to be dipped in a cauldron of poison to control it.
