 Similar terms recur in Egyptian sources from later centuries with more certain correspondence to the Greek etymon of "Blemmyes".In Coptic, Ⲃⲁⲗⲛⲉⲙⲙⲱⲟⲩⲓ, "Balnemmōui", is widely accepted as equivalent to Greek Βλέμμυης, "Blémmuēs".The Greek term first appears in the third century BC in one of the poems of Theocritus and in Eratosthenes, who is cited in Strabo's "Geographica" (first century AD).
