Then he and Lugh met… . ”Lift up my eyelid, lad,” said Balor, “so I may see the talkative fellow who is conversing with me.” The lid was raised from Balor’s eye. Then Lugh cast a sling stone at him which carried the eye through his head, and it was his own host that looked at it. He fell on top of the Fomorian host so that twenty-seven of them died under his side; and the crown of his head struck against the breast of Indech mac De Domnann so that a gush of blood spouted over his lips. (The Second Battle of Mag Tuired)
Here’s my depiction of Lugh Lámhfhada facing down the Balor of the Evil, King of the Formors. I sketched it out by hand and then inked and colored in Autodesk Sketchbook Copic Edition. I based all my Gaelic Myth art work off of the Legend of Zelda: The Wind Waker art style and surviving Celtic art sources.
