Beher is the Aksumite god of the sea, named alongside Astar and Mahrem in the protective triad of the royal inscriptions and rendered Poseidon in the Greek throne dedication of the Monumentum Adulitanum. His name derives from the Semitic word for 'sea', though the Ge'ez term bāḥr also carries the sense 'land/region', and in the parallel recensions of Ezana's inscription RIÉ 185 the name Medr ('earth') stands in his place — so that Beher and Medr are understood as a single chthonic power or as interchangeable deities of land and sea. The theonym survives into Christian Ge'ez within ʾəgziʾabəḥer, the standard word for God. Aksumite tradition makes him a son of Astar and brother of Mahrem.
