Pyrotecnic Weapons, Hand-gun late 14th century

Unfortunately, the very worn Arabic inscription on the rear of the portion
of the Islamic Gun (1) has yet to be interpreted.  The massive late medieval
iron arrow (2) found in the citadel of Damascus and now in the Musee del'
Armee in Paris was probably fired from such a gun.
