Medieval Seal with 2,000-Year-Old Roman Gemstone Discovered in Essex

A remarkable medieval seal, featuring a 2,000-year-old Roman gemstone, was recently unearthed in Gosfield, Essex, U.K., by a metal detectorist in late 2024. Experts from the U.K.'s Portable Antiquities Scheme have since analyzed the 800-year-old object, revealing its unique composition.

A Blend of Eras

Lori Rogerson, a finds liaison officer for Essex, highlighted the rarity of an artifact combining elements from such disparate historical periods.

"The uncommon nature of an object composed of elements from two distinct time periods."

The silver seal itself measures 1 inch (27.5 millimeters) in length and weighs 0.23 ounces (6.44 grams). Its design includes a loop, suggesting it was likely worn suspended, possibly as a necklace.

The Inscription: "Richard's Secret"

An intriguing mirror-image inscription encircles the bezel, reading "SECRETUM.RICARDI," which translates to "Richard's secret" or "the secret [seal] of Richard." Adding to its character, a cross pattée—a Christian symbol often associated with the Knights Templar—is also present on the seal. Both the mirror-image inscription and the intaglio chariot design were crafted to appear correctly when pressed into wax.

The Ancient Roman Gemstone

At the heart of the seal is a stunning carnelian gemstone. It is intricately engraved with an image of a charioteer in a two-horse chariot, depicted holding reins and a whip, indicative of a circus race. This carved gemstone is remarkably ancient, dating back to the late first century B.C. or early first century A.D. This makes it at least 1,200 years older than the silver seal matrix it now adorns.

Signifying Status and Knowledge

Rogerson theorized that Richard, the owner, might have intentionally chosen the Roman gemstone to showcase his knowledge of the classical world and his ability to acquire prestigious objects from distant times and places. Such a distinguished artifact would have undoubtedly served as a powerful indicator of the owner's social status during the medieval period.

Treasure Act Consideration

The Gosfield seal has been formally submitted for consideration as treasure under the U.K.'s Treasure Act of 1996. This submission is based on its valuable silver composition and its age, which significantly exceeds the 300-year threshold. The Braintree Museum in Essex has already expressed keen interest in acquiring the object, pending the outcome of a treasure inquest.
