Later correspondence with de Grazia himself was to indicate-(and this became more obvious when his quantavolution series was finally published)-that he had not investigated Velikovsky's work in any depth and he ended up by repeating many of the erroneous assertions and mythological interpretations contained in Worlds in Collision. Worse than that, de Grazia, as I myself had once done, continued to build on these errors, extending their natural fall-out to include the cosmic catastrophes of those eras preceding that of the Exodus. On top of all that, while de Grazia acknowledged the universality of the mythological record, he showed a distinct penchant for using Greek sources as the yard-stick against which to measure his cosmic scheme. This tendency, which had exhibited itself on an earlier occasion, had already been criticized by Peter James but de Grazia, perhaps because he was already too deeply committed to his views, chose to ignore it. Thus de Grazia saw it as imperative to accommodate the Greek generation of gods in which each deity was considered to have been the offspring of the preceding one. "road to Saturn" In Worlds in Collision Velikovsky had made the unfortunate statement that "The mythologies of all peoples concern themselves with the birth only of Venus, not with that of Jupiter, Mars, or Saturn"-which, of course, is simply not so. In fact, with perhaps one exception, every planetary deity was described as having been born of another. But because Velikovsky had interpreted the birth of Athene from the head of Zeus as the expulsion of the cometary Venus from the planet Jupiter, de Grazia deceived himself into believing that the actual ejection of one planet from another has to be implied by all such divine births. And Milton, unfortunately, followed suit.
