Fachtna

Fachtna is an Old Irish masculine given name, possibly derived from the Old Irish word facht meaning "malice". In Irish mythology, Fachtna is best known as a legendary high king of Ireland. According to some traditions, he was the husband of Neasa and the father of Conchobar mac Nessa, the king of Ulster in the Ulster Cycle of Irish legend.

Etymology

The etymology of Fachtna is uncertain. While it may derive from facht ("malice"), another theory suggests a connection to the Latin facundus ("eloquent"). The name is related to other Irish names such as Fachnan, Fachtnán, Fachanan, and Faughnan. It also appears in place names like Kilfaughnabeg (from Cill Fachna Bheag).

Mythological Significance

Fachtna is not widely detailed in surviving texts, but his association with Conchobar places him at the beginning of the Ulster Cycle. His wife Neasa is a central figure; she installed her son Conchobar as king of Ulster by convincing her husband Fergus mac Róich to temporarily give up the throne. Fachtna's paternity of Conchobar is supported by some traditions, though others name the druid Cathbad as Conchobar's biological father.
