X-Group culture in the context of Blemmyes
The Blemmyes (Ancient Greek: Βλέμμυες or Βλέμυες, Blémues [blé.my.es], Latin: Blemmyae) were an Eastern Desert people who appeared in written sources from the 7th century BC until the 8th century AD. By the late 4th century, they had occupied Lower Nubia and established a kingdom. From inscriptions in the temple of Isis at Philae, a considerable amount is known about the structure of the Blemmyan state.
The Blemmyes are usually identified as one of the components of the archaeological X-Group culture that flourished in Late Antiquity. Their identification with the Beja people who have inhabited the same region since the Middle Ages is generally accepted.
