THE association of the name of the god Seth with the Great Pyramid--a structure which appears to embody or to bear a relation to the chief scientific truths recognised by the ancient world, throws light on certain ideas entertained as to the nature of that deity. The god of intelligence of the Egyptians was Thoth, the Hermes of the Sabaeans. Hermes was, however, called the son of Seth, and this deity is in some sense to be identified with Thoth. In a passage of the Book of the Dead, the former has the name Tet which, according to Bunsen, intimates that Thoth inherited many of the attributes of Seth.
