35 years ago, the discovery of No. 1 and No. 2 sacrificial pits in Sanxingdui made the ancient Shu civilization wake up and startle the world. Last weekend, the Sanxingdui site released the latest archaeological excavation results, which raised the mystery of ancient Shu civilization. Among them, the most attractive is the unearthed fragments of gold masks.
In the newly discovered pit No. 5, a large number of gold products, including a unique gold mask, were unearthed from Sanxingdui archaeological excavation. Compared with the gold masks unearthed in pits 1 and 2 of Sanxingdui site, the newly unearthed gold masks are particularly thick and distinctive.
Yu Mengzhou, deputy leader of the Sanxingdui archaeological excavation team and professor of the school of archaeology, culture and Museum, Sichuan University: in fact, at that time, I didn't know what it was. I only knew that it was gold foil because it was very wrinkled. Moreover, it was originally turned over. Besides it, there were several larger pieces beside it. There are things on the gold foil. Archaeologists carefully cleaned out its outline and found that the gold foil has the largest volume.
At present, No.3, No.4, No.5 and No.6 pits have been excavated to the utensil layer, while No.7 and No.8 pits are being excavated to fill the pit. More than 500 pieces of important cultural relics have been unearthed, such as fragments of gold masks, bird shaped gold ornaments, gold foil, painted bronze head portraits, giant bronze masks, bronze sacred trees, ivory, exquisite ivory carvings, jade CONGs, jade stone tools and so on.
For these newly excavated cultural relics, archaeologists divide the archaeological area into several small squares, and record the plane and section images by using three-dimensional fine scanning. When the data accumulate to a certain amount, it can help to find out which direction the ancient Shu people filled the pit from.
All the information, not only its layer, the layer, the location of the pit, even if the information is lost, a look at the two-dimensional code, a scan to reflect the latitude and longitude, you can immediately determine which part of the pit, the label is unique, is the identity card of the utensil or specimen.
It should also be noted that for the first time, a silicone film made by 3D printing was used in this excavation. The silicone film can be attached to the surface of the bronze statue, which is better than soft cloth and film.
