Yarhibol in the context of Temple of the Gadde

The Temple of Bel (Arabic: معبد بعل), sometimes also referred to as the "Temple of Baal", was an ancient temple located in Palmyra, Syria. The temple, consecrated to the Mesopotamian god Bel, worshipped at Palmyra in triad with the lunar god Aglibol and the sun god Yarhibol, formed the center of religious life in Palmyra and was dedicated in AD 32. The temple would have been closed during the persecution of pagans in the late Roman Empire in a campaign against the temples of the East made by Maternus Cynegius, Praetorian Prefect of Oriens, between 25 May 385 to 19 March 388. Its ruins were considered among the best preserved at Palmyra, until they were further destroyed by the Islamic State in August 2015. The arched main entrance into the temple is still intact, as well as its exterior walls and fortified gate.

Aglibol (Palmyrene Aramaic: 𐡰𐡢𐡫𐡡𐡥𐡫 ʿGLBWL; عجل بعل) is a god from Palmyra, originating from a north Syrian immigrant community. He is a moon god who was worshiped in the ancient Syrian city of Palmyra as part of a triad alongside Bel and Yarhibol, and associated with the sun god Malakbel.

Evidence of Aglibol's worship is primarily epigraphical. The earliest known mention of Aglibol was an inscription which dates back to 17 BCE and associates him with the sun god Malakbel. Several other inscriptions made by the Bene Komare also associate him with Malakbel, including a bilingual inscription from 122 CE in which Aglibol and Malakbel sponsor a citizen by the name of Manai for his piety.
