Balor

BAL-or

The Fomorian king whose single deadly eye can destroy an army, killed by his own grandson Lugh at the Second Battle of Moytura.

Balor of the Evil Eye leads the Fomorians as their king, and carries a single great eye that was closed from birth and only opened — by several attendants prying back its lid — on the battlefield, where its gaze alone kills or withers whatever it falls on. A prophecy holds that Balor will be killed by his own grandson, so he imprisons his daughter to prevent her ever bearing a child — a plan that fails when Lugh is conceived regardless and later raised in secret. At the Second Battle of Moytura, Lugh confronts Balor as his eye is being forced open, and drives a sling-stone through it and out the back of his head, turning the deadly gaze back on the Fomorian ranks behind him and breaking their army. Balor's death by his own grandson's hand is one of the best-known fulfilled prophecies in the whole mythology.

Frequently Asked Questions

Who is Balor?

Balor is the king of the Fomorians, a race of hostile beings opposed to the Tuatha Dé Danann, famed for a single giant eye whose gaze could kill or devastate whatever it fell upon.

Why did Balor's eye have to be lifted open?

The eye was so destructive that it had to be kept closed and lifted open with a hook through its heavy lid by attendants whenever Balor wished to use it in battle, making it a weapon that had to be deliberately deployed rather than a constant threat.

How did Balor die?

He was killed by his own grandson Lugh at the Second Battle of Mag Tuired, struck through the fatal eye with a sling-stone in fulfillment of a prophecy that Balor would be slain by his daughter's son.
