Neolithic sword found in Chongqing
Seven tombs dating to the Han dynasty were found in December in southwest China. Among the artifacts in the tombs were some very ancient objects, such as this bronze sword, apparently intended for ritual use, said to date from the Neolithic period.
I picked up this image and story from Dream Art Gallery. They have probably got it from a Chinese news report, but no credit is given, and I don’t know the original source.
