The text systematically examines Old Testament myths and miracles, tracing their parallels in the religious traditions of ancient heathen nations. It opens with a rigorous comparison of the creation and fall of man as narrated in Genesis against the cosmogonies of ancient Persia, Etruria, and Babylon, highlighting the existence of two distinct and contradictory accounts of creation within the Hebrew text. The author then surveys universal deluge traditions, connecting the biblical flood of Noah to the Chaldean account of Xisuthrus and similar legends in Hindu, Greek, and American Indian mythologies, while noting the absence of such cataclysms in Egyptian history. Subsequent chapters dissect the tower of Babel, the trial of Abraham, and Jacob's ladder, arguing that the latter symbolizes the ancient doctrine of the transmigration of souls through planetary spheres, akin to the Mithraic mysteries.
The narrative further explores the exodus, the giving of the law on Sinai, and the exploits of Samson, establishing their structural and thematic identity with the myths of the Greek sun-god Bacchus and the Phenician Hercules. Further examination covers Jonah and the whale, circumcision, and various prophetic miracles, demonstrating their roots in solar mythology and ancient agricultural cults. The study concludes with a critical history of the Pentateuch, illustrating how Hebrew writers compiled and adapted these legends during and after the Babylonian captivity.
