A unique Byzantine inscription from the fourteenth century was recently discovered on Giresun Island in the Black Sea; inscribed on a terracotta tablet, it is considered to be one of a kind because it is written in the greek-type regional alphabet of the Empire of Trebizond.

Giresun Island lies 1.2 kilometers (0.7 miles) from the modern Turkish province of Giresun (the ancient Greek Kerasous) on the southeastern coast of the Black Sea. Giresun Island stands out as the only island with human settlement in the East Black Sea along with its mythological stories and historical remains. Some of the island's ancient names are Aretias (Greek: Ἀρητιάς), Areos Nesos (Greek: Ἄρεος νῆσος) (means island of Ares), Chalceritis (Greek: Χαλκερίτις) and Puga. In historical times, the island was likely used by 6th or 5th century BC Greek colonists from the mainland city of Kerasous (presently the city of Giresun).

Excavations have been ongoing on this beautiful and historic island under the supervision of Giresun University associate professor Gazanfer Iltar since 2009. On the island are the ruins of a roofless stone temple, fortifications and ramparts, and two wine or oil presses. The roofless temple was in ancient times attributed to the Amazons who held religious rituals there. Archaeological studies suggest it was built in the Classical-Hellenistic era. A black round stone about 4 meters diameter, called Hamza Taşı in Turkish, is located in the ruins of the temple. In the present day, this stone is the starting point for a walk as part of the annual Aksu festival and it considered a wishing stone for fertility and health. Archaeology findings suggest the stone was sacred to a Roman stone cult or a Cybele Cult.

Iltar's team has discovered a written artifact on the island for the first time this year with the unveiling of a 14th-century inscription. Iltar said that the inscription is of great importance as it will shed light on the history of the island and Giresun region.

Noting that the inscription was found on the floor of the tower structure on the island, the academician continued: “The artifact belongs to the period of Alexios III Megas Komnenos, the emperor of Trebizond. The inscription states that the structures and walls on the island were commissioned by the venerable Maria, the wife of Pinkernes Kyriakos, the son of Giresun Governor Roustam. The name of Roustam in the inscription also gives us clues about the strategic marriages between the Turkmen beys in the region and the Komnenos dynasty."

The inscription was made of terracotta, measures 30 by 50 centimeters (11 inches to 19 inches) and was written with goose feathers.

Explaining that the inscription was translated by an academic from Russia, Iltar said: "The inscription provides us with several pieces of information and perspectives. For example, the title of 'pinkernes' means the cup bearer of the emperor of Trebizond. It is actually a high court position in terms of diplomacy, and a pinkernes should be considered one of the closest people to the emperor. Therefore, it is understood that the governor of Giresun at the time was very close to the emperor of Trebizond.”

“The importance of the inscription increases even more as it reveals the relations in the region in the past and it is a unique work written in a regional alphabet of the Empire of Trebizond.” Iltar added that archaeological excavations will continue on the island in 2022 as well.

Empire of Trebizond and its Greek origins

The Empire of Trebizond, or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire that flourished during the 13th through to the 15th century, consisting of the far northeastern corner of Anatolia (the Pontus) and the southern Crimea. The empire was formed in 1204 with the help of the Georgian queen Tamar after the Georgian expedition in Chaldia and Paphlagonia, commanded by Alexios Komnenos a few weeks before the sack of Constantinople.

The Trapezuntine monarchy survived the longest among the Byzantine successor states. The Despotate of Epirus had ceased to contest the Byzantine throne even before the Nicaean reconquest and was briefly occupied by the restored Byzantine Empire c. 1340, thereafter becoming a Serbian dependency later inherited by Italians, ultimately falling to the Ottoman Empire in 1479. Whilst the Empire of Nicaea had restored the Byzantine Empire through restoring control of the capital, it ended in 1453 with the conquest of Constantinople by the Ottomans. Trebizond lasted until 1461 when the Ottoman Sultan Mehmed II conquered it after a month-long siege and took its ruler and his family into captivity. The Crimean Principality of Theodoro, an offshoot of Trebizond, lasted another 14 years, falling to the Ottomans in 1475.

Trebizond already had a long history of autonomous rule before it became the center of a small empire in the Late Middle Ages. Due to its natural harbours, defensible topography and access to silver and copper mines, Trebizond became the pre-eminent Greek colony on the eastern Black Sea shore soon after its founding. Its remoteness from Roman capitals gave local rulers the opportunity to advance their own interest. In the centuries before the founding of the empire the city had been under control of the local Gabras family, which – while officially still remaining part of the Byzantine Empire – minted its own coin.

The rulers of Trebizond called themselves Megas Komnenos ("Great Comnenus") and – like their counterparts in the other two Byzantine successor states, the Empire of Nicaea and the Despotate of Epirus – initially claimed supremacy as "Emperor and Autocrat of the Romans". However, after Michael VIII Palaiologos of Nicaea recaptured Constantinople in 1261, the Komnenian use of the style "Emperor" became a sore point. In 1282, John II Komnenos stripped off his imperial regalia before the walls of Constantinople before entering to marry Michael's daughter, accepting his legal title of despot. However, his successors used a version of his title, "Emperor and Autocrat of the entire East, of the Iberians and the Perateia" until the Empire's end in 1461.
