Keats mistakenly thought Cortez had dodgy boxer's first name! (5)
Keats "On first looking into Chapman's Homer":
Or like stout Cortez when with eagle eyes
He star’d at the Pacific—and all his men
Look’d at each other with a wild surmise—
Silent, upon a peak in Darien.
But it was Balboa, not Cortez.
In the "Rocky" films, his surname was Balboa.
