The ranks of the 'Terracotta Army' that guards the mausoleum of the First Emperor of China has grown as archaeologists reported on Monday finding 220 new warriors.

Emperor Qin Shi Huang's tomb lies buried at the heart of a 249 feet (76 meter) -tall mound in what is today Xi'an's Lintong District, in the northwest of China.

The necropolis surrounding the unopened tomb harbours more than 8,200 of the earthenware sculptures, which were first uncovered in 1974 by local farmers.

The tomb has four main pits, each of which were lain east of Emperor Qin's tomb, as if to protect him from the states to the east that he had conquered in life .

The latest, third, excavation of pit one — which has been underway for a decade — has exposed around 4300 square feet (400 sqm), the Beijing Youth reported.

The newest batch of Terracotta soldiers come from five different ranks, including a previously unknown one dubbed 'lower than the lowest', Shaanxi TV reported.

Among the other recent finds from the necropolis include a golden camel figurine which is believed to be the oldest of its kind known from China.

'The terracotta warriors in the mausoleum are lined up the same way as real soldiers thousands of years ago in the Qin Dynasty (221–206 BC),' China Cultural Relics Academy member Liu Zheng told the Global Times.

'So, archaeologists can research real military systems of the dynasty with these excavated warriors,' he added.

For example, senior military officers in the Qin dynasty stood at the front of their formations with their swords in their hands, Mr Liu explained.

In addition, he added, the senior officers wore different hair accessories to those of their subordinates.

Alongside the new soldiers, archaeologists also unearthed weapons and twelve horses during this latest run of excavations within the tomb.

The new terracotta soldiers also have well-preserved original colourations.

'When these pottery figurines were first excavated, they were mostly coloured — with red belts and dark armour — but we lacked preservation skills and the colours faded,' Mr Liu said.

'But, this time, improved technologies are enabling the newly found figurines to retain their vivid colours.'

'Exhibition, excavation and conservation of the mausoleum are proceeding at the same time.'

The Terracotta Army is just one part of the wider necropolis complex surrounding the emperor's tomb, which archaeological surveys have suggested covers some 38 square miles (98 square kilometres).

The necropolis is believed to represent a scaled-down version of Qin's imperial palace — complete with offices, halls, stables and even a park.

The central tomb has never been excavated, however, largely in fear that the tools required to do so safely and without damaging the tomb may not yet exist.

What are China's terracotta Warriors? The 8,000-strong burial army built by the first emperor Each of these 2,000-year-old figures was given an individual personality and was coloured The Terracotta Army is a form of funerary art buried with the first emperor, Qin Shi Huang, in 210 to 209 BC and whose purpose was to protect the emperor in his afterlife. Arguably the most famous archaeological site in the world, it was discovered by chance by villagers in 1974, and excavation has been on-going at the site since that date. An extraordinary feat of mass-production, each figure was given an individual personality although they were not intended to be portraits. The figures vary in height according to their roles, with the tallest being the generals. Current estimates are that there were over 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which are still buried. Since 1998, figures of terracotta acrobats, bureaucrats, musicians and bronze birds have been discovered on site. They were designed to entertain the Emperor in his afterlife and they are of crucial importance to our understanding of his attempts to control the world even in death. Advertisement
