Javier Teixidor has found evidence that belief in a supreme god developed during the first millennium B.C. The Phoenician and Aramaic inscriptions he discusses indicate a trend toward monotheism that facilitated the spread of Judaism, Christianity, and Islam.

Here, then, is a major reinterpretation of the religious life of the Near East in the Greco-Roman period based on a reliable source of information.
