Walter de Milemete was an English scholar[1] who in his early twenties was commissioned by Queen Isabella of France to write a treatise on kingship for her son, the young prince Edward, later king Edward III of England called De nobilitatibus, sapientiis, et prudentiis regum in 1326.[2] The Treatise includes images of siege weapons and what is probably the first[3] illustration of a firearm: a pot-de-fer.[4] One of the marginal border illustrations in the Milemete Treatise shows a soldier firing a large vase-shaped cannon, the arrow-shaped projectile is seen projecting from the cannon which is pointed at a fortification.[5] In the 1331 siege of Cividale, German knights used guns which were probably very similar to Milemete weapons.[6]
The treatise includes an illustration of St. George giving Prince Edward a shield decorated with coat of arms.[7] The manuscript, in a red velvet binding, is now held by the library of Christ Church, Oxford. The treatise also depicts a group of knights flying a firebomb kite laden black-powder filled firebomb over the wall of city.[8]
