Minstrel to King Théoden. He composed a song of which the Riders of Rohan sang at the funeral of Théoden:

"Out of doubt, out of dark, to the day's rising
he rode singing in the sun, sword unsheathing.
Hope he rekindled, and in hope ended;
over death, over dread, over doom lifted
out of loss, out of life, unto long glory."

Gléowine made no other song thereafter.
