A long-lost chapter of biblical text has been discovered nearly 1,500 years after it was initially written.

According to the study published in the journal New Testament Studies, the previously hidden segment is one of the earliest translations of the gospels.

The medievalist Grigory Kessel of the Austrian Academy of Sciences unearthed the concealed chapter beneath three layers of text using ultraviolet photography.

“The tradition of Syriac Christianity knows several translations of the Old and New Testaments," Kessel said in a statement. "Until recently, only two manuscripts were known to contain the Old Syriac translation of the gospels."
