Endubis

Endubis (c. 270 – c. 300) or Endybis was a late-3rd-century sovereign of the Kingdom of Aksum in East Africa (modern-day Ethiopia and Eritrea). He was among the earliest rulers in the Horn region to mint his own coins; the Aksumite currency of his reign was issued in gold and silver denominations and bore inscriptions in Koine Greek.

On the coins of Endubis so far recovered, either of two mottos were engraved. On some coins he described himself as "ΑΞΩΜΙΤΩ ΒΑϹΙΛΕΥϹ", "king of Axum". On others appeared the motto "ΒΙϹΙ ΔΑΧΥ", "bisi Dakhu"; this is the first appearance of the title "bisi", which S. C. Munro-Hay believes is related to the Ge'ez word "be'esya", "man of".[1]
