And, lest I forget to mention it, UR, where Hammurabi ruled ( and where we're now fighting/making over BTW )is where Avram ( Abraham ) was born.
and which Abraham and his family left, taking the central idea of a single, all powerful, God with him. He also took with him a notion from En Heduanna, Sargon's daughter (Sargon was one of Hamurabai's predecessors) and priestess of the moon goddess En (since morphed into Allah, according to a lot of fundamentalist sources) of a personal relationship with the deity (she is also credited with being the first named author in history). And from Abraham and his "legitimate" child the Jewish nation was born. And they have the begats to back that up...
In the meantime he left behind his oldest (but illegitimate) son, Ishmael, and Ishmael's mother, who was his wife's slave. Folklore has it that the Arabs are all descended from Ishmael (what happened to everyone else, I wonder?), and that is their claim to "ownership" of the one we know as God, Jehovah, Yahweh, etc.
However, the descendants of Ishmael showed scant concern for that God until around the year 700, when an illiterate gigolo (pbuh) had a hallucinatory vision in a cave. He had his wife's scribes take parts of the holy writings of others (particularly Jews and Christians) and said "they got it wrong," and changed the things he didn't like to make himself the all powerful voice of god. He had anyone who disagreed with him killed. And he particularly hated the Jews, because they represented the line of Abraham which had spurned his ancestor. They had to acknowledge him as the one true voice of god, renounce the Torah, or die. He gave them 3 chances. When they refused ("let us considert this" they said) he had his followers start killing them, and they've been killing the Jews, and their Christian "heretics," for 1300 years. And His followers still pray to a big black rock in a city on the Arabian peninsula and to a moon god, 5 times a day.
Hatfields and McCoy's got nothing on this family feud.
Hey, Mr. Rushdie, you got room for another person to hide out with you? I feel a fatwah coming on...
