A writing set comprising of a bone dip pen and inkwell dating back to the late Roman era has been unearthed in the ancient Greek city of Bathonea in Istanbul, a Turkish university has announced.

The archeologists unearthed the 1,600-year-old writing set during ongoing archaeological excavations at the ancient site of Bathonea, said a statement by Kocaeli University in western Izmit.

The writing set is believed to have once belonged to a merchant.

The discovery goes down in the history of archeology as the first time an intact writing set has been unearthed at an ancient dig.

Close examination of the inkwell found traces of ancient red and black ink still present. Red ink was used exclusively by state officials and courtiers at that time, according to experts.

Considering that the use of writing was quite rare 1,600 years ago, the significance of the discovery grows more evident.

During the same excavations, archeologists also found evidence of an earthquake that rattled the city and caused the complete collapse of the famed dome of Hagia Sophia in the year 557.

The renowned dome suffered several partial collapses over the centuries.

Hagia Sophia, built in 532, served as a church until 1453 when it became a mosque.

From 1935 onwards, it served as a museum, but in July 2020 it returned to its mosque status while leaving the architectural wonder open to domestic and foreign visitors.

In 1985, Hagia Sophia was added to the UNESCO World Heritage List. It is among Türkiye’s top tourism destinations.

The excavations in Bathonea, in a suburb of Istanbul known as Küçükçekmece, are being done by the Culture and Tourism Ministry and Kocaeli University under the supervision of Şengül Aydıngün, an archaeologist at the university.
