A bronze signet ring depicting the Lighthouse of Alexandria has been discovered underwater in the Mediterranean off the coast of Alexandria, Egypt. A joint team from the European Institute for Underwater Archaeology (IEASM) and the Egyptian Ministry of Tourism and Antiquities found the artifact within the remains of an ancient palace on the submerged island of Antirhodos.
Marine archaeology continues to yield remarkable insights into the ancient world, particularly along the submerged coastlines of Egypt where ancient structures sank due to earthquakes and erosion. This particular artefact represents a notable first in the study of one of the seven wonders of the ancient world. Researchers hope that ongoing exploration and digital reconstruction efforts will benefit from the detailed imagery preserved on the ring.
The Discovery
The artefact was found by a diver sitting underwater within the architectural remains of a palace on the now-submerged island of Antirhodos. This site once served as a major centre of power during the Ptolemaic period. The IEASM team, working alongside the Egyptian Ministry of Tourism and Antiquities, confirmed that this is the first time a signet ring featuring an engraving of the Lighthouse of Alexandria has been recovered from an archaeological context.
Franck Goddio, president of IEASM, noted in a statement that the discovery of the ring is exceptionally important because it was excavated directly within the legendary palace of Antirhodos. The palace was utilised by Egyptian pharaohs reigning during the Ptolemaic dynasty, a line of rulers descended from one of Alexander the Great's generals who ruled Egypt from 304 to 30 BC.
What Archaeologists Found
The recovered artefact is a bronze signet ring featuring an engraved image that bears striking similarities to historical depictions of the Lighthouse of Alexandria found on second-century coins. In antiquity, individuals who wore signet rings used them to press impressions into soft materials such as clay and wax to establish official seals or personal signatures.
The recovery of this specific ring inside the palace ruins suggests that the building may have hosted administrative functions directly connected to the operation, maintenance, or taxation associated with the lighthouse. While the engraving on the ring shows some signs of wear, experts have been able to analyse its distinct stylistic features to confirm its iconographic significance.
Historical Background
The Lighthouse of Alexandria was constructed on the island of Pharos around 280 BC and stood at an impressive height exceeding 328 feet, or 100 metres. Renowned classical writers, including Pliny the Elder, classified the monument among the wonders of the world. The lighthouse remained operational through the classical era and into the Middle Ages until severe earthquakes and coastal erosion triggered its structural collapse and subsequent disappearance beneath the Mediterranean Sea.
Throughout its history, the lighthouse underwent several modifications. At its pinnacle stood a statue, potentially representing Zeus, holding an oil lamp that projected light to guide mariners safely navigating the perilous coastal waters. Over recent years, marine archaeological operations off the coast of Alexandria have located massive architectural blocks, vastly expanding our physical understanding of the monument's true scale and appearance.
Scientific Analysis
Scholars and historians have examined the newly recovered ring to compare its iconography with known ancient artefacts. Doris Behrens-Abouseif, a professor emeritus of the history of art and archaeology at the University of London, noted that thousands of ancient coins from Alexandria display similar depictions of the lighthouse dating from the Ptolemaic and Roman periods, which spanned from 29 BC to AD 395.
Other independent researchers and academics have pointed out specific asymmetrical details near the summit of the engraved lighthouse. Andrew Chugg, an independent researcher and author specialising in the Pharos lighthouse, suggested that this asymmetrical feature might represent a plume of smoke rising from the oil lamp held by the crowning statue. Margaret Miles, a professor emeritus of art history and classics at the University of California, Irvine, observed that the ring could have functioned as a signet for a merchant seeking to signal their operational base or commercial connection to the famous city of Alexandria.
Why This Discovery Matters
The identification of a signet ring featuring the Lighthouse of Alexandria inside a royal palace provides tangible evidence of how the monument functioned as a symbol of civic identity and imperial authority. Because the lighthouse was globally famous in antiquity, its profile was rapidly adopted as an emblem representing the entire city of Alexandria.
Furthermore, the artefact bridges the gap between numismatic evidence and glyptic art, confirming that the imagery circulating on state-issued coinage was also embraced in personal jewellery worn by administrators or merchants. This adds a layer of depth to our understanding of daily administrative life and imperial iconography during the Ptolemaic dynasty.
What's Next?
Marine archaeologists and specialists in digital reconstruction plan to integrate the precise visual data from the ring's engraving into ongoing projects aimed at rendering a digital model of the lighthouse. Continued dives around the submerged island of Antirhodos and adjacent sectors of Alexandria's sunken royal quarters may yield additional artefacts that clarify the administrative operations of the Ptolemaic court.
As researchers press forward with underwater excavations and advanced imaging technologies, the lost landscape of ancient Alexandria slowly returns to view. What other hidden administrative secrets might still lie buried beneath the Mediterranean silt within the ruins of the Antirhodos palace?
Frequently Asked Questions
Where was the bronze ring discovered?
The bronze signet ring was found underwater in the remains of an ancient palace on the submerged island of Antirhodos off the coast of Alexandria, Egypt. The joint excavation was conducted by the European Institute for Underwater Archaeology and the Egyptian Ministry of Tourism and Antiquities.
What does the engraving on the ring depict?
The ring features an engraving of the Lighthouse of Alexandria, a famous wonder of the ancient world. Scholars note that the design closely mirrors depictions found on second-century coins from the region.
Who used the palace where the ring was found?
The palace on Antirhodos island was utilised by Egyptian pharaohs during the Ptolemaic period between 304 and 30 BC. The discovery of the signet ring in this location suggests the building served administrative functions connected to the lighthouse.
How tall was the original Lighthouse of Alexandria?
Built around 280 BC on the island of Pharos, the lighthouse stood more than 328 feet tall. It continued to guide mariners until it was destroyed by earthquakes and coastal erosion during the Middle Ages.
