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.
[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.
