The history of the Chinese Fast Sword Draw (出劍法) dates back to the Han dynasty, 2,000 plus years ago. Unfortunately, there are no known manuals for these techniques and historically illustrations are rare. This depiction of a seated swordsman drawing his sword is from a scroll originally painted by Gu Kaizhi ( 顧愷之) in the 4th century. While Gu’s original version of this scroll, The Admonitions of the Instructress to the Court Ladies (女史箴圖) has not survived, later copies of this work have.
The two following later copies of this scroll date to the Tang (dated between the 6th and 8th century AD) and Song dynasties. As such they are likely the oldest known illustrations of a Chinese Swordsman Preforming the Fast Sword Draw (出劍法). They are also the only know depiction of a seated Chinese sword drawn know to date. Given the age of the two paintings, it is difficult to make out the finer details. What we can see is that seated swordsman’s grip is palm out with his fingers wrapping over the grip prepared to draw and strike downward. His rear hand is well back toward the rear of the scabbard, palm down.
A skeptic might understandable suggest that the seated figure is actually wielding a cudgel. Given the lack of visible detail, this would be an understandable suggestion. However, there is no reason for a wooden club to be gripped at the rear end just prior to swinging it. And given that what appears to be bear is just before the seated man, if it were some sort of cudgel and not a sword ready to be drawn, it is more likely he would be gripping it with two hands not holding the the rear end palm down.
Note: the Tang period example of The Admonitions of the Instructress to the Court Ladies is in the collection of the British Museum in London. The Song period (960-1279) example is the property of the Palace Museum in Beijing.
