In Greek mythology, King Gelanor (Ancient Greek: Γελάνωρ), of Argos welcomed Danaus and his daughters. When an oracle told him to give Danaus his kingdom, he did so. He wanted to sell the Danaides into slavery following their murder of their husbands, but Danaus and the gods dissuaded him. He is simply called the "King" in Aeschylus's Suppliant Maidens. Alternatively, it was not an oracle, but an omen, that induced Gelanōr to renounce his kinship in favor of Danaos. The omen was of a wolf attacking a herd of cattle grazing beside the city-wall, and killing the leading bull. His real name was Pelasgus, the name /Gelanōr/ is a literary devise meaning 'laughter' : he was so called because he had initially laughed at the claim to kingship over Argōs by Danaos. Gelanōr was son of Sthenelās.
In Helen of Troy, a novel by Margaret George, Gelanor is a fictional character who acts as an advisor to the Spartans under Menelaus. He accompanies Helen when she goes to Troy.
She died during a thunderstorm, on the darkest morning in
years, and I was ruined and undone and left raining like
a leaf.
It was fourteen degrees below on a screeching March 23.
Don't look me in the eyes now, there ain't nothing in
there to see.
Jet black, slick and wide and glued to the walls.
Last night the whole of hell came down to bathe and dine
with us and I met the strangest woman with skin that
smelled like rust.
She said "I've been in a crowd of thousands and each one
had eyes like you.
Yes, I've been in front of millions and they all had eyes
like you.
