Yi Hu Pao (翼虎砲)

Yi Hu Pao (翼虎砲, lit. 'Winged tiger cannon') was a late Ming period large handgonne or light cannon. It was said to be more powerful than other cannons (debatable, given the difference in size and bore), very accurate, and fairly portable. It was mounted on a wooden frame that allows its elevation to be adjusted.

Interestingly, similar weapons were in use in the Holy Roman Empire (and elsewhere in Europe) since early sixteenth century, but did not seem to gain prominence and quickly phased out by other, more advanced firearms.
