LIMA, Peru – A rare and fragile pre-Incan funeral shroud was displayed to reporters Monday, part of the first batch of ancient Paracas textiles that Sweden is returning to Peru 80 years after they were smuggled out by a diplomat.

The intricately colored shroud, measuring 41 inches by 21 inches, and 88 other textiles were donated to a museum in Gothenburg in the early 1930s by Swedish consul Sven Karell. He had secreted them out of Peru after they were discovered in the Paracas Peninsula, a desert south of Lima where the extremely dry climate helped protect the Alpaca wool fibers.

Despite being some 2,000 years old, “it is perfectly preserved,” said Krzysztof Makowski, a University of Warsaw archaeologist who has studied the shroud as a professor at the Catholic University of Peru. “Across the world, the discoveries of textiles of this age are much rarer than any precious metal.”

“Textiles are very fragile. There are very few countries in the world that have conserved fabrics. Peru is one of them.”

The so-called Shroud of Gothenburg is uniquely complex. It includes some 80 different color tones and subtones such as blue, green, yellow, red and orange. It is divided into 32 frames decorated with items resembling condors, frogs, cats, corn, cassava and human-like figures.

Some researchers believe the shroud may be a sort of calendar related to the tracking of farming seasons, said Jahl Dulanto, an archaeologist at the University of Illinois at Urbana- Champaigne who leads the Paracas investigation team at the Catholic University of Peru.

Dulanto said experts still do not fully understand how the shroud’s creators achieved the combination of sewing techniques and pigments.

The shroud and three other pieces were flown to Peru last week, fulfilling a friendly agreement reached with the Museum of World Culture in Gothenburg in 2013.

The rest of the Paracas textiles will return to Peru over the next seven years.
