Traces of rare purple dye mentioned in Bible passages found in 'remarkable' discovery

Archaeologists recently uncovered traces of a rare purple dye associated with biblical-era luxury in an unexpected place.

The York graves date from the late third or early fourth century A.D. One infant was laid to rest alongside two adults in a stone coffin - while the other was buried in a lead coffin.

Researchers recently analyzed the preserved remains and textiles in the burials. Using chemical testing, they found traces of Tyrian purple.

"The babies were wrapped in a fine textile of Tyrian purple embellished with gold thread - a cloth of the highest possible status and luxury known in the Roman world," an April 30 statement from the University of York noted. 

The university said that "during the Roman period, the dye was a commodity valued at up to three times the price of gold."

One biblical reference to purple textiles appears in Acts 16:14, which describes a female merchant.

The verse says, "And they clothed him in a purple cloak; and after twisting some thorns into a crown, they put it on him."

Officials said the textiles survived thanks to the Roman ritual of "pouring liquid gypsum over the clothed and shrouded bodies of the dead."

"The gypsum gradually hardened, protecting imprints and fragments of textiles, as well as the dyes and substances originally present in the fabrics," the release added.

The discovery marks the "first time traces of the dye have been found on Roman textile remains in York," officials said.

Professor Maureen Carroll, a project director with University of York's Department of Archaeology, called the discovery "remarkable."

The archaeologist added that the research "tells us a lot about the importance of children in Roman York and the willingness of the family to give their baby the best possible send-off in tragic circumstances."

York, once known as Eboracum in Roman times, was founded around 71 A.D. as a military fortress.

Fox News Digital reached out to the University of York for comment.

The site, Tel Shiqmona, "can unequivocally be identified as a specialized facility for large-scale and long-term production of the lucrative purple dye," according to the study's authors.

The site dates back as early as 1100 B.C., and researchers said the site had an "unparalleled" number of artifacts related to purple dye manufacturing.
