Baalshamin or Ba’al Šamem (Aramaic: ܒܥܠ ܫܡܝܢ), lit. ‘Lord of Heaven(s)’, a title applied to different gods at different places or times in ancient Middle Eastern inscriptions, especially in Canaan/Phoenicia and Syria. The title was most often applied to Hadad, who is also often titled just Ba‘al. Baalshamin was one of the two supreme gods and the sky god of pre-Islamic Palmyra in ancient Syria (Bel being the other supreme god).
