Avars Retreat from Tomis

A Byzantine fortress withstands the siege

The Avar siege of the Byzantine stronghold of Tomis was lifted as their leader Bayan I retreated northward across the Danube. The fortress, perched on the shores of the Black Sea in modern-day Romania, had withstood the Avar assault, demonstrating the resilience of Byzantine frontier defenses. The Avar retreat offered Constantinople a brief reprieve from the relentless pressure of barbarian incursions along its Danubian border.

Archaeologists working at Knossos on the island of Crete discovered the first clay tablets inscribed with hieroglyphic writing in a script that would later be called Linear A. The discovery opened a window into the mysterious Minoan civilization, the first advanced society in Europe. Linear A remains undeciphered to this day, a tantalizing puzzle that guards the secrets of a people who built palaces and commanded the seas four thousand years ago.
