Archaeologists working at the ancient site of Hippos in Israel have discovered a 2,100-year-old sling bullet inscribed with Greek text, marking what researchers describe as a first-of-its-kind find worldwide.

The lead projectile bears the Greek word meaning 'learn,' which archaeologists interpret as a sarcastic message intended for enemy forces. The discovery was made at Hippos, an ancient city located near the Sea of Galilee.

Sling bullets were commonly used weapons in ancient warfare, but finding one with an inscription is extremely rare. The Greek text on this particular projectile represents the first documented example of such messaging on ancient ammunition.

The site of Hippos has been an active archaeological dig for years, with researchers uncovering various artifacts that provide insight into ancient life in the region. The city has historical significance both for its Greek and Roman periods, as well as its later Christian community.

Researchers noted that the discovery adds to understanding of ancient military practices and the psychological warfare tactics employed during conflicts in the Hellenistic period. The bullet dates to approximately the first century BCE, during a time when the region saw various military campaigns and territorial disputes.
