At one time, animal sacrifice was the most common form of public worship in the West.
So what happened to it?
We tend to think of Judaism as mother and Christianity as daughter, but in fact Christianity and Rabbinic Judaism are sister religions that arose at the same time in response to the self-same trauma: the destruction of the Jerusalem temple in 70 CE.
In ancient Hebrew religion, anyone could build an altar anywhere and offer up sacrifice there, but with the rise of the Jerusalem temple, a hard-fought process of centralization set in which eventually banned sacrifice anywhere else, on the logic of “one god, one temple.”
Dating from more than 40,000 years ago, the Lion “Man” of Hohlenstein Stadel is the oldest uncontested zoomorphic figure that we know of. Carved from mammoth ivory, and standing about a foot high, the bipedal image combines feline and human characteristics. Since the lions of prehistoric Europe had no manes and there is no clear indication of sex, we cannot say for certain whether the figure is intended as female or male.
