A recent underwater archaeological expedition off the coast of the Greek island of Kythera has yielded the discovery of a small marble decorative fragment. Interest in this piece of stone has been elevated, as it is believed to have originated from the Parthenon. The fragment was recovered from the wreck of the Mentor, the infamous brig owned by Lord Elgin that sank in 1802 while transporting looted antiquities from the Acropolis of Athens to Britain.
This significant find provides a tangible link to the controversial history of the Elgin Marbles and highlights the ongoing efforts to uncover the secrets still hidden within the sunken vessel. The discovery marks the first time that a piece of sculptural architectural decoration has been identified among the remains of the ship’s cargo since systematic excavations began.
A Tiny Drop of History
One of the standout discoveries of the 2025 excavation season is a small marble fragment featuring a carved decorative drop, known as a gutta, which is characteristic of Classical Greek architecture. According to the Greek Ministry of Culture, the fragment measures 9.3 centimeters in length and 4.7 centimeters in width, with the decorative drop measuring 6.51 centimeters in diameter and 2.2 centimeters in height.
Researchers believe the piece may have been an architectural element, such as an epistyle regula or a cornice mutule. Preliminary analysis reveals that the dimensions of the gutta align precisely with measurements recorded by the renowned architect Anastasios Orlandos for the decorative elements of the Parthenon’s entablature.
“The fragment has maximum dimensions of 9.3 cm. (length) x 4.7 cm. (width), and the drop has a diameter of 6.51 cm and a height of 2.2 cm. The dimensions of the drop can be compared with the measurements of A. Orlandos, regarding the decorative drops of the epistyle of the Parthenon,” stated the Greek Ministry of Culture.
Ongoing conservation work and further study are expected to confirm the exact monument from which the fragment originated.

Exploring the Wreckage of the Mentor
The 2025 underwater research campaign was directed by archaeologist Dr. Dimitris Kourkoumelis-Rodostamos, deputy head of the Ephorate of Underwater Antiquities. The systematic excavation focused on two specific areas to the west and north of the surviving section of the ship’s hull explains the Greek Reporter coverage.
In the first trench, located about five meters west of the preserved hull, archaeologists found no remains of the ship’s wooden structure. This absence confirms the hypothesis that the hull decomposed rapidly due to exposure on the seabed and the aggressive salvage methods employed by sponge divers in 1802. These divers, hired by Lord Elgin’s secretary, had to break through the ship’s planking to reach the heavy crates of marble trapped in the hold.
The second excavation trench, situated north of the surviving keel, yielded more fruitful results. While no wooden planks were found, the team recovered various artifacts related to the ship’s equipment and fragments of everyday utensils used by the crew. Among the interesting finds were pieces of copper plating from the ship’s exterior hull, used to protect the timber from marine life and deterioration.
Evidence also suggested that the lower part of the hull and the keel had been reinforced with lead sheets. A section showing the junction between the copper and lead plating was identified during the excavation. Additionally, a ceramic insulation slab, likely belonging to the ship’s cooking hearth, was found near the stern.

The Legacy of Lord Elgin’s Ship
The story of the Mentor is inextricably linked to the controversial removal of the Parthenon sculptures. In 1802, the privately owned brig was loaded with 17 crates of antiquities taken from Greece by agents of Lord Elgin, the British ambassador to the Ottoman Empire.
During its voyage from Piraeus to Malta, the ship encountered severe weather and struck rocks off the port of Avlemonas near Kythera, sinking in approximately 23 meters of water. While all 12 crew members were rescued, the precious cargo sank to the bottom of the sea. Lord Elgin subsequently organized a massive, two-year salvage operation using local sponge divers to retrieve the crates, which eventually made their way to the British Museum in London explains Days of Art.

The recent discovery of the marble fragment serves as a poignant reminder of this historical event and the enduring debate surrounding the repatriation of the Elgin Marbles. As underwater archaeologists continue to meticulously explore the remains of the Mentor, each artifact recovered adds another layer of detail to the story of the ship and its disastrous journey, shedding light on a pivotal moment in the history of cultural heritage.
