Medieval Artillery - Use in Europe

Use in Europe

In Europe, the first mention of gunpowder's composition in express terms appeared in Roger Bacon's "De nullitate magiæ" at Oxford, published in 1216. Later, in 1248, his "Opus Maior" describes a recipe for gunpowder and recognized its military use:

We can, with saltpeter and other substances, compose artificially a fire that can be launched over long distances ... By only using a very small quantity of this material much light can be created accompanied by a horrible fracas. It is possible with it to destroy a town or an army ... In order to produce this artificial lightning and thunder it is necessary to take saltpeter, sulfur, and Luru Vopo Vir Can Utriet. —

In 1250, the Norwegian Konungs skuggsjá mentioned, in its military chapter, the use of "coal and sulphur" as the best weapon for ship-to-ship combat.
