Description
-
This crossbow mechanism held by the Shanghai museum is dated to the Han dynasty. Its specific location of unearthing is not listed.
The mechanism is made of bronze and it comprises most of the typical parts of a Chinese crossbow mechanism. In this photo, the mechanism is positioned upside down. Thus, the long rectangular protrusion at the bottom of the mechanism is the sight, or wangshan (望山). Not visible in the photo, there are two small hooks that stick out in front of the sight which are a part of the same component as the wangshan and serve as the nut, or ya (牙). The rectangular handle protruding from the left of the mechanism is the trigger, or xuandao (悬刀), and within the bronze casing, or guo (郭) there is a sear, or gouxin (钩心), which hangs exposed from the mechanism in this photo, connecting the sight and nut and the trigger. The mechanism is held together by two bronze axle pins. The top surface of the bronze casing which is oriented at the bottom in this image has a groove that goes down the middle which would continue onto the wooden stock of the crossbow. This groove would be where the arrow rests during drawing and aiming.
