Kaleb of Axum

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.”
