Note 1 — CANTO XXXI.

Iphimedeia bore to Poseidon two sons, “but they were short- lived, godlike Otus and far-famed Ephialtes whom the fruitful Earth nourished to be the tallest and much the most beautiful of mortals except renowned Orion, for at nine years old they were nine cubits in breadth, and nine fathoms tall. They even threatened the immortals, raising the din of tumultuous war on Olympus, and strove to set Ossa upon Olympus and wood-clad Pelion upon Ossa, in order to scale heaven. But Jove destroyed them both.” Odyssey, xi. 306-317.
