Kaleb (c. 520) is perhaps the best-documented, if not best-known, king of Axum situated in modern day Eritrea and Ethiopia.
Procopius of Caesarea calls him "Hellestheaeus", a variant of his throne name Ella Atsbeha or Ella Asbeha (Histories, 1.20).
Variants of his name are Hellesthaeus, Ellestheaeus, Eleshaah, Ella Atsbeha, Ellesboas, and Elesboam, all from the Greek Ελεσβόάς, for “The one who brought about the morning” or “The one who collected tribute.”
Kaleb, a name derived from the Biblical character Caleb, is his given Christian name; ʾOn both his coins and inscriptions he left at Axum, as well as Ethiopian hagiographical sources and king lists, he refers to himself as the son of Tazena.
He may be the "Atsbeha" or "Asbeha" of the Ethiopian legends of Abreha and Asbeha, the other possibility being Ezana's brother Saizana.
