The Hag Magid was the site of a temple built to honor the Hag of Megiddo, a famous wizzardess turned god, whose mummy was expected to resurrect at the onset of Armageddon.
The Hag was the patron goddess of misfortune and error and her adherents celebrated her deity and powers by dumping sacrifices onto the temple floors—then dropping the pottery they were carried in so that it would break. In the picture you can see an upside down sacrificial pot. This was the process of building the tel or hill that covered the temple over the millennia.
Thanks wb, I think of the poor bastards who dated her in high school.
