History of crossbows

rdf:langString History of crossbows

rdf:langString It is not clear where and when the crossbow originated, but it is believed to have appeared in China and Europe around the 7th to 5th centuries BC. In China the crossbow was one of the primary military weapons from the Warring States period until the end of the Han dynasty, when armies composed of up to 30 to 50 percent crossbowmen were not unheard of. The crossbow lost much of its popularity after the fall of the Han dynasty, likely due to the rise of the more resilient heavy cavalry during the Six Dynasties. One Tang dynasty source recommends a bow to crossbow ratio of five to one as well as the utilization of the countermarch to make up for the crossbow's lack of speed. The crossbow countermarch technique was further refined in the Song dynasty, but crossbow usage in the military continued to decline after the Mongol conquest of China. Although the crossbow never regained the prominence it once had under the Han, it was never completely phased out either. Even as late as the 17th century, military theorists were still recommending it for wider military adoption, but production had already shifted in favor of firearms and traditional composite bows. In the Western world a crossbow known as the gastraphetes was described by the Greco-Roman scientist Heron of Alexandria in the 1st century AD. He believed it was the forerunner of the catapult, which places its appearance sometime prior to the 4th century BC during the Classical period. Other than the gastraphetes, the only other evidence of crossbows in ancient Europe are two stone relief carvings from a Roman grave in Gaul and some vague references by Vegetius. Pictish imagery from medieval Scotland dated between the 6th and 9th centuries AD do show what appear to be crossbows, but only for hunting, and not military usage. It's not clear how widespread crossbows were in Europe prior to the medieval period or if they were even used for warfare. The small body of evidence and the context they provide point to the fact that the ancient European crossbow was primarily a hunting tool or minor siege weapon. An assortment of other ancient European bolt throwers exist such as the ballista, but these were torsion engines and are not considered crossbows. Crossbows are not mentioned in European sources again until 947 as a French weapon during the siege of Senlis. From the 11th century onward, crossbows and crossbowmen occupied a position of high status in medieval European militaries, with the exception of the English and their continued use of the longbow. During the 16th century military crossbows in Europe were superseded by gunpowder weaponry such as cannons and muskets. Hunters continued to carry crossbows for another 150 years due to its silence. There is a theory that medieval European crossbows originate from China but some differences exist between the two trigger mechanisms used in European and Chinese crossbows.
