The Great Pyramid of Egypt was involved in many medieval and Renaissance cults, especially in the Rosicrucian and other occult traditions, but it was not until 1859 that modern Pyramidology was born. This was the year that John Taylor, an eccentric painter in a London publishing firm, issued his The Great Pyramid: Why was it Built? And Who Built it?
Taylor never visited the Pyramid, but the more he studied its structure, the more he became convinced that its architect was not an Egyptian, but an Israelite acting under divine orders. Perhaps it was Noah himself.
