Pompeii's stunning secret is uncovered after 2,000 years: Archaeologists are amazed to discover a 'high quality' fresco depicting Helen of Troy during excavations at the ancient Roman city

Nearly 2,000 years since it was buried by volcanic rubble, the lost city of Pompeii is yielding even more astonishing discoveries.

Archeologists have uncovered remarkably preserved 'fresco' paintings on a wall at a former private residence along Via di Nola, one of Pompeii's longest streets. 

One of the stunning artworks depicts Helen of Troy, a beautiful woman in Greek mythology, meeting Paris, prince of Troy, for the first time. 

According to legend, the resulting elopement between the two sparked the Trojan War of the 12th century BC. 

It's one of many buried treasures found at the Italian former city, which was famously destroyed in AD 79 by the lethal eruption of Mount Vesuvius. 

Painted onto a black background, the scene shows Helen of Troy, a beautiful woman in Greek mythology (left with a nurse or maid), meeting Paris, prince of Troy (right with his dog). The little Greek writing says: Alexander Helen. Alexander is another name for Paris

The frescos have been discovered in the 'black room', an 'imposing' banquet hall with elegant black walls at a former private residence along Via di Nola. 

It's being called the black room because it was painted black, likely to mask soot from oil lamps that would have burnt. 

Conversely, the room's mosaic floor is comprised of more than a million tiny and intricately arranged white tiles. 

'Here people gathered to feast after sunset, the flickering light of the oil lamps made the images seem to move, especially after a few glasses of good Campania wine,' said Gabriel Zuchtriegel, director of the Archaeological Park of Pompeii. 

Dr Sophie Hay, a British archaeologist who works at the Archaeological Park of Pompeii, said the 'high quality' frescos used the black walls as the background for the scene. 

'The dining room seems to be vaguely unique in the sense that normally there are figurative panels with a border around them,' she told the Times.

'But the ones in that room are painted directly on to the background.

'So it's like they're doing something new, which is really nice but obviously they never got to enjoy it.' 

A second newly-discovered fresco in the room depicts the naked Greek god Apollo trying to seduce the priestess Cassandra.

Pompeii was famously destroyed by the eruption of Mount Vesuvius, but excavations are still yielding ancient discoveries. According to the BBC , as much as third of the lost city has still to be cleared of volcanic debris

In an effort to seduce Cassandra, Apollo gave her the power of prophecy – being able to see into the future. 

But when she refused him, he cursed her so that nobody would ever believe her prophecies. 

Dr Andrew Sillett, a classics lecturer at the University of Oxford, has described the frescos as 'pretty cool' because they were likely done close to the eruption. 

'Most paintings we have are somewhat worn as a result of having been painted years before,' he told MailOnline. 

'It looks like these were buried very shortly after having been painted.' 

A third fresco in the black room, meanwhile, shows Leda, mother of Helen of Troy. 

As Dr Sillett explains, Leda is holding a 'randy swan', who is not all he seems. 

'This long-necked waterfowl is, in fact, none other than the lord of Olympus himself, Zeus, who is pictured here in the act of conceiving the woman whose face would launch a thousand ships,' he said. 

A fourth fresco, which is barely uncovered from the ancient volcanic material, shows a female figure appearing to hold a dish.

Today, the ruins of Pompeii are a popular tourist attraction, drawing a million visitors a year. Located on the west coast of Italy, Vesuvius is the only active volcano in continental Europe

Pompeii was famously destroyed by the eruption of Mount Vesuvius, but excavations are still yielding ancient discoveries. 

According to the BBC, as much as third of the lost city has still to be cleared of volcanic debris. 

A new documentary about the findings – Pompeii: The New Dig – will be broadcast at 9pm, Monday April 15, on BBC2. 

Earlier in the year, Dr Hay and colleagues revealed a stunning artwork of Phrixus and Helle, two twins from Greek mythology, at a building called the House of Leda. 

The twins are depicted travelling across the sea on a magical golden-woolled ram while fleeing from their evil stepmother. 

Experts are hopeful that the newly-found frescos will go on display for the public to enjoy at Pompeii, which gets almost four million visitors a year. 

The stunning artwork is a 'fresco' - a type of wall painting - but damage to the wall has meant it is not entirely preserved

Rewind 2,000 years and Pompeii, 14 miles south-east of Naples, was a buzzing city. But on August 24, AD 79, it was destroyed by the eruption of nearby Mount Vesuvius 

Pompeii was a thriving and wealthy Roman city with a population of around 11,000 before Mount Vesuvius erupted, ejecting molten rock, pulverized pumice and hot ash at 1.5 million tons per second. 

The catastrophic event destroyed the settlements of Pompeii, as well as the settlements Herculaneum, Torre Annunziata and Stabiae, killing up to 16,000 in the process. 

After the eruption, bodies of the victims at Pompeii were famously preserved in a protective shell of ash before they eventually decayed.

Since the mid 1800s, the voids that these bodies left behind were eventually filled with plaster casts to recreate their final moments. 

How Pompeii and Herculaneum were wiped off the map by devastating eruption of Mount Vesuvius 2,000 years ago

What happened?  

Mount Vesuvius erupted in the year AD 79, burying the cities of Pompeii, Oplontis, and Stabiae under ashes and rock fragments, and the city of Herculaneum under a mudflow.  

Mount Vesuvius, on the west coast of Italy, is the only active volcano in continental Europe and is thought to be one of the most dangerous volcanoes in the world.  

Every single resident died instantly when the southern Italian town was hit by a 500°C pyroclastic hot surge.

Pyroclastic flows are a dense collection of hot gas and volcanic materials that flow down the side of an erupting volcano at high speed.

They are more dangerous than lava because they travel faster, at speeds of around 450mph (700 km/h), and at temperatures of 1,000°C.

An administrator and poet called Pliny the younger watched the disaster unfold from a distance. 

Letters describing what he saw were found in the 16th century.  

His writing suggests that the eruption caught the residents of Pompeii unaware.

He said that a column of smoke 'like an umbrella pine' rose from the volcano and made the towns around it as black as night.

People ran for their lives with torches, screaming and some wept as rain of ash and pumice fell for several hours.  

While the eruption lasted for around 24 hours, the first pyroclastic surges began at midnight, causing the volcano's column to collapse.

An avalanche of hot ash, rock and poisonous gas rushed down the side of the volcano at 124mph (199kph), burying victims and remnants of everyday life.  

Hundreds of refugees sheltering in the vaulted arcades at the seaside in Herculaneum, clutching their jewelry and money, were killed instantly.

The Orto dei fuggiaschi (The garden of the Fugitives) shows the 13 bodies of victims who were buried by the ashes as they attempted to flee Pompeii during the 79 AD eruption of the Vesuvius volcano

As people fled Pompeii or hid in their homes, their bodies were covered by blankets of the surge.

While Pliny did not estimate how many people died, the event was said to be 'exceptional' and the number of deaths is thought to exceed 10,000.

What have they found?

This event ended the life of the cities but at the same time preserved them until rediscovery by archaeologists nearly 1700 years later.

The excavation of Pompeii, the industrial hub of the region and Herculaneum, a small beach resort, has given unparalleled insight into Roman life.

Archaeologists are continually uncovering more from the ash-covered city.

In May archaeologists uncovered an alleyway of grand houses, with balconies left mostly intact and still in their original hues.

Some of the balconies even had amphorae - the conical-shaped terra cotta vases that were used to hold wine and oil in ancient Roman times.

The discovery has been hailed as a 'complete novelty' - and the Italian Culture Ministry hopes they can be restored and opened to the public.

Upper stores have seldom been found among the ruins of the ancient town, which was destroyed by an eruption of Vesuvius volcano and buried under up to six meters of ash and volcanic rubble.
