Archaeologists have unearthed a pre-Hispanic fresco depicting mythological scenes in northern Peru, which had been lost for a century.
"It's an exceptional discovery, first of all, because it is rare to unearth wall paintings of such quality in pre-Colombian archaeology," said Sam Ghavami, the Swiss archaeologist who led excavations that uncovered the mural in October.
Ghavami spent four years looking for the rock painting, which he believes could be around 1,000 years old, with a team of Peruvian students.
"The composition of this painting is unique in the history of mural art in pre-Hispanic Peru," added the archaeologist, who trained at the University of Freiburg in Germany.
The fresco forms part of the Huaca Pintada temple, which belonged to the Moche civilization that flourished between the 1st and 8th centuries, and venerated the Moon, the rain, iguanas, and spiders.
The uncovered mural is about 30 meters (98 feet) long, and its images in blue, brown, red, white, and mustard yellow paint remain extremely well preserved.
In one section, a procession of warriors can be seen heading toward a birdlike deity.
The painted images "appear to be inspired by the idea of a sacred hierarchy built around a cult of ancestors and their intimate links with the forces of nature," said Ghavami.
He told AFP that deciphering the mural's message would form part of his research, but he believes it "could be interpreted as a metaphorical image of the political and religious order of the region's ancient inhabitants."
The discovery is also unusual as it shows a mixture of styles and elements of two pre-Incan cultures: the Moche and the Lambayeque, who lived on Peru's north coast between 900 and 1350 A.D.
The mural's existence was only known via black and white photos taken in 1916 by the German ethnologist Hans Heinrich Bruning, who was living in Peru when he heard of the site after treasure hunters tried to loot it, but found nothing of value.
As the years went on, thick foliage took over, and no one had tried to look for the paintings until it piqued Ghavami's interest and he went in search of the long-lost fresco.
However, first he had a long battle to obtain permission from the family who own the land where the mural was found.
