My book, The Constellation of Horus, is based on scientific sources and texts, and it incorporates notes and references, as well as a bibliography. More than five thousand years ago, the inventions and achievements of the ancients had reached an astonishingly high level. Most of the technology on which those civilizations were founded had, by that time, already been brought to perfection. That is evident in Imhotep’s Book of Ordination of the Temple. In his capacity as Hierogrammateus, Imhotep listed the following domains:
Cosmography
Geography
Astronomy of the Solar system
Geography of Egypt
Riverbasin of the Nile
Description of the sacred instruments and emblems
Metrology, and all means that serve to worship the divine (see Imhotep, par.98, D.Wildung)
