Moloch was represented as a huge bronze statue with the head of a bull. The statue was hollow, and inside there burned a fire which colored the Moloch a glowing red. Children were placed on the hands of the statue. Through an ingenious system the hands were raised to the mouth (as if Moloch were eating) and the children fell into the fire where they were consumed by the flames. The people gathered before the Moloch were dancing on the sounds of flutes and tambourines to drown out the screams of the victims.
According to some sources, the Moloch in the Old Testament is not a god, but a specific form of sacrifice.
