Furbaide Ferbend

Furbaide Ferbend (or Ferbenn) is a character from the Ulster Cycle of Irish mythology. He is the son of the Ulster king Conchobar mac Nessa and one of his wives, Eithne, daughter of the High King Eochu Feidlech. While she was pregnant, Eithne was murdered by her sister Medb, Conchobar's ex-wife and later queen of Connacht, by drowning in a stream. Her son was delivered by Caesarian section, and was named Furbaide, explained as deriving from Old Irish "urbad", "a cutting". His epithet "Ferbend", "horned man", comes from his helmet, which has a bull's horns.

In later life he avenged his mother's death. Medb had taken to bathing in a pool on an island. Furbaide measured the distance from the pool to the shore with a rope, and practiced with his sling until he could hit an apple on to off a stake from that distance. The next time he saw Medb bathing, he shot the nearest missile to hand - a piece of cheese - at her, and killed her.
