Gold ceremonial masks dating back 3,000 years, possibly worn by a priest and used for sacrificial purposes, are some of more than 500 items unearthed from six rectangular pits in

The priceless cultural relics – unearthed at the Sanxingdui archaeological site in the province of Sichuan, southwest China – also include bird-shaped ornaments, two kinds of silk and a bronze statue adorned with depictions of ‘beasts’.

Only about half of the gold mask is still fully intact, but experts believe it is around 84 per cent pure gold and in its original state weighed close to 500 grams (one pound).

Another gold mask, found in sacrificial pit ‘number three’, is of a similar design but is remarkably preserved and almost completely intact.

Researchers who began digging at the site in 2019 said most of the 500 items were crafted out of gold, bronze, jade and ivory, according to the South China Morning Post.

They believe the pits may have been used for sacrificial purposes by members an as-yet-unknown civilisation, and that the objects now found within them were ritually burned before being buried.

The findings were shared in a blog post by the government of Chengdu, which is the capital of southwestern China’s Sichuan province.

Sanxingdui is a well-known archaeological site and tourist hotspot outside of Chengdu.

The mask and the other exciting new findings will ‘help deepen the understanding of the cultural relationship between the Chengdu Plain and the surrounding areas’, according to officials, although much mystery still surrounds the golden mask.

‘At present, it is inferred that this golden mask is also used for sacrifice, but because it is much larger than a human face, it is unlikely to be worn by a person,’ said an unnamed expert cited in the post.

‘It is still impossible to draw an accurate conclusion at present, and further archaeological excavations are needed.’

If the complete weight of this golden mask were more than 500 grams, it would make it the largest golden mask found in China, as well as the heaviest golden object found in the country.

The mask was found in pit number five out of six, but another two pits – seven and eight – are now also being excavated and could reveal the other half.

In sacrificial pit number three, a ‘rare, well-preserved, and exquisitely decorated’ bronze square statue, dubbed ‘Big Mouth’, was unearthed.

The two-foot-tall statue – which is in a typical southern style of the late Shang Dynasty that ruled in the second millennium BC – is decorated with animal and bird heads.

‘The complete square bronze statue has never been seen before the Sanxingdui site,’ the government of Chengdu says in the post.

Archaeologists said they found two kinds of silk – one in the ashes of the sacrificial pit a large amount of silk traces and other other wrapped around the bronze ware.

The function of silk was raised ‘to a metaphysical level’, according to the post, when it was used for sacrificial purposes.

‘Silk serves as a carrier and medium for communication between heaven, earth, man and god,’ it says.

‘The earliest silk must not be used to make beautiful clothes, it must be used to communicate with the world, people and gods.

‘Bronze Sacred Tree’. The Sanxingdui site has traces of a ‘highly brilliant and splendid bronze civilisation’, according to the government of Chengdu

‘Silk, silkworm, and mulberry embodies the concept of harmony between man and nature with Chinese characteristics.’

Sanxingdui was initially stumbled upon in 1929. In 1986, two ceremonial pits containing more than 1,000 items were uncovered during a major excavation, according to CNN.

One of them items unearthed from the number two sacrificial pit in 1986 was a bronze sculpture of human head with well-preserved gold mask, currently held at Sanxingdui Museum.

A third pit was found in late 2019, and another five pits were found last year.
