Archaeologists in southwestern Bulgaria have uncovered an exceptionally rare ancient surgical instrument at the Greek city of Heraclea Sintica, offering new insight into medical practices in the ancient Mediterranean. The artifact, identified as a lithotomy knife used to remove bladder stones, was unearthed inside a room adjacent to the city’s temple during excavations led by Dr. Lyudmil Vagalinski, the project’s director.
The discovery, announced on Friday, marks one of the few times such a specialized medical tool has been found in an archaeological context. Heraclea Sintica, founded in the 4th century BCE, was a thriving urban center in the region, and the presence of the instrument suggests advanced surgical knowledge among its inhabitants. “This find underscores the sophistication of medical practices in ancient Greek colonies,” Vagalinski stated. The knife, crafted from iron, bears signs of extensive use, indicating it was a functional tool rather than a ceremonial object.
The excavation site, located near the modern village of Rupite, has been a focal point for archaeological research since 2007, when Bulgarian and Greek teams began systematic excavations. Heraclea Sintica’s urban layout, including a theater, temples, and public baths, reflects its importance as a cultural and political hub in the Roman province of Thrace. The city’s decline in the 6th century CE, likely due to earthquakes and shifting trade routes, preserved its remains beneath layers of sediment.
This discovery adds to a growing body of evidence highlighting the medical advancements of the ancient world. Similar lithotomy knives have been found in Pompeii and other Mediterranean sites, but Heraclea Sintica’s example is particularly well-preserved. Researchers plan further analysis to determine whether the instrument was locally manufactured or imported, which could reveal trade connections in the region.
The find comes amid renewed international interest in ancient Greek medicine, including a recent facial reconstruction of Alexander the Great and the reopening of Pompeii’s House of Apollo Citharoedus . These projects, alongside discoveries like the Heraclea Sintica knife, are reshaping understanding of daily life, health, and innovation in antiquity.
For Bulgaria, the discovery reinforces the country’s role as a crossroads of ancient civilizations. The Ministry of Culture has announced plans to integrate the artifact into a new exhibition at the National Archaeological Museum in Sofia, pending conservation work. The knife’s unveiling is scheduled for later this year, coinciding with the 150th anniversary of Bulgaria’s liberation from Ottoman rule.
