The father of Aholibamah, one of Esau’s wives. While feeding his father’s asses in the desert, he is said to have found the "mules" Genesis 36:24. But the Hebrew word is suppose to mean rather "warm springs;" and such springs are found on the eastern coast of the Dead sea, which was not far from the dwellings of the Seirites, to whom Anah belonged. In this region was a place afterwards celebrated among the Greeks and Romans for its warm springs, and called by them Callirrhoe.
