Warring States bronze spear

This is a bronze spear during the Warring States period, a long weapon. But today, I don't want to talk about this weapon, but I want to talk about another secret that I found in it. Under the magnifying glass, we can see that on the front and back sides of the spear, there are many small regular patterns in the middle and qiáo. The pattern tells us the fact that this bronze spear, when accompanied by the owner's burial, was first wrapped in silk and then buried underground with other burial articles. After more than 2,400 years of spring, summer, autumn and winter, the carbonization of the silk fabric was not there, but its imprint was clearly left on this bronze spear.

We know that as early as the Han dynasty, there was a prosperous Silk Road to the Western Regions, illustrating that the silk production at that time was already considerable. In fact, the history of silkworm larvae in our country is much longer. Not only did the story of the ancestors of the ancestors teach silkworm rearing, but scientific archeology also discovered many spinning wheels in the Neolithic period and witnessed the legendary human ancestors inventing textiles. The era is basically credible. In addition, traces of silk fabric with a plain structure have also been found on Shang Dynasty bronze gongs and bronze gongs unearthed in the archaeology. Unfortunately, as a physical object, before 2006, it was only found in a number of Han tombs, such as the Mawangdui Han Tomb in Changsha, where more complete silk and dresses were unearthed. Until the second half of 2007, after the silk and fabrics were unearthed in the tombs of Jing An and Zhou in Jiangxi, as a major discovery, we witnessed earlier fabrics with higher levels than ordinary silk fabrics and yarns. Jin. I had the honour of seeing this tapestry through the bronze spear during the Warring States Period in the 13 years (1994) before the Jingan silk fabric was unearthed. I was very satisfied with the data at the time. From the traces on the bronze spear, the warp and weft densities can be clearly seen, and it can be seen that the meridians are significantly thicker than the wefts. I see this as a surprise for the bronze wares.

Let's look at the little bronze arrow, the bronze gong. Bronze figurines were found in the Erlitou cultural site and were used until the Han Dynasty, after which they were replaced by iron crucibles. There are more than two thousand years of history in the use of bronze enamels. Has such a simple shape changed in shape? some. Because it is a weapon, it is the most easily optimized and improved in the war. We can see from the physical that the bronze gongs before the Spring and Autumn Period are basically double-winged flat crickets. Starting in the middle of the spring and autumn, the cross-section becomes a triangular razor blade and prevails, gradually eliminating the two-winged gong. Why is this? Because you are the target of killing in flight. Therefore, in the early days, humans could easily think of wings for flying objects. The wings were like wings of a bird. There were blades on both sides that could kill and wound. Therefore, two wings were cast. However, in the long-term actual combat, people find that the wide-winged beak is vulnerable to the natural influence of the wind, and affects the accuracy. The wider the wings, the greater the impact. By changing the section of the radon to equal triangles, the effect of the wind is reduced, accuracy is improved, and the penetrating resistance of the delta wing is reduced, the depth of killing is increased, and the combat effectiveness of the army is improved.
