Sembrouthes
Sembrouthes was a King of the Kingdom of Aksum. He is known only from a single inscription in Ancient Greek that was found at Dekemhare (Deqqi Mehari) in modern-day Eritrea, which is dated to his 24th regnal year.
S. C. Munro-Hay places his reign in a gap between `DBH and DTWNS, or c.250. However, W.R.O. Hahn, in a study published in 1983, assigns Sembrouthes to the 4th century, between Aphilas and Ezana. He also identifies him with Ousanas or the legendary Ella Amida.
Munro-Hay also suggests that Sembrouthes may have been the ruler who erected the anonymous Monumentum Adulitanum. The latter is an inscription at Adulis that Cosmas Indicopleustes made a copy of for king Kaleb of Axum.
