Hadad, literally 'the crasher,' was the foremost deity of the Armean peoples of Syria. He was synonymous with Baal-Hadad who convulsed the earth, shook the mountains, and blasted the trees. Rulers of Damascus in biblical times were known as Bar-Hadad. There is a reference in Zechariah that he fulfilled a fertility role like Baal, with even a lament for the dead god. A.G.H.
