Orlando was invulnerable except in the sole of his foot, and even there nothing could injure him except the prick of a pin.--Italian Classic Fable.
Siegfried was invulnerable except in one spot between the shoulders, on which a leaf stuck when he dipped his body in the dragon’s blood.--The Nibelungen Lied.
⁂ The Promethĕan unguent rendered the body proof against fire and wounds of any sort. Medea gave Jason some of this unguent.--Classic Story.
Vulture (The Black), emblem of the ancient Turk, as the crescent is of the modern Ottoman empire.

O’ershadows half the earth, whose dismal sight
Frightened the Muses from their native spring,
Already stoops, and flags with weary wing.
