China, western Asia, 11th-12th century. Forged iron, 4 7/8” total length, and just under 2” width. See Arms and Armour of the Crusading Era #769k for a related example of much less dramatic form This example is the largest we’ve seen including in literature. In the course of his conquests, Genghis Kahn encountered war elephants in India and Burma, Later, his son, Kublai Khan encountered them when Narathihapate of present-day Burma invaded Yunnan Province.
