Dogon People -- Ancient Egyptian Connections: Sirius Isis and Sothis
Dogon People -- Ancient Egyptian Connections: Sirius Isis and Sothis
Sirius in Ancient Egypt
Ancient Egypt's relationship with Sirius was more intimate and more institutionally significant than that of any other ancient civilisation. Sirius -- called Sothis in Greek transliteration of the Egyptian Sopdet -- was the most important star in the Egyptian astronomical-religious system.
The Sothic Calendar
The foundation of Egyptian timekeeping was the heliacal rising of Sirius -- the first annual appearance of the star just before sunrise after approximately 70 days of invisibility (when too close to the Sun in the sky to be seen). This annual event:
- Heralded the annual flooding of the Nile -- the event on which Egyptian agriculture entirely depended
- Marked the Egyptian New Year
- Occurred around the summer solstice at the latitude of Memphis
- Was the basis of the Sothic cycle -- a 1,461-year astronomical cycle used by Egyptologists to establish absolute dates in Egyptian history
Sirius as Isis
In Egyptian religion, Sirius was identified with the goddess Isis -- the mother goddess, wife of Osiris, mother of Horus. The heliacal rising of Sirius (Sothis/Isis) heralded the return of Osiris (the Nile flood). The myth of Isis searching for Osiris's dismembered body and restoring him parallels, in Dogon terms, the sacrifice and promised return of the Nommo.
Robert Temple argued the Isis-Sirius identification represents the same knowledge preserved in Dogon tradition -- that ancient Egypt knew Sirius as a system of cosmic significance and encoded this in religious mythology. Temple's Egyptian Sirius B connection is interpretive: Egyptian texts do not describe Sirius B explicitly.
Possible Routes for Knowledge Diffusion
If Dogon astronomical knowledge came from ancient Egypt rather than extraterrestrial contact:
- Trans-Saharan trade networks: Well-documented for thousands of years; cultural and astronomical knowledge could have traveled these routes
- Dogon oral traditions of Egyptian origin: Some Dogon traditions state their ancestors came from Egypt or Libya; if historically real, knowledge could have traveled with migrating populations
- Shared proto-African astronomical tradition: Both Dogon and Egyptians may have inherited knowledge from a common, older African tradition
Assessment
The Egyptian connection is plausible for general astronomical awareness of Sirius -- but cannot explain the specific properties of Sirius B (orbital period, density, ellipticity). Ancient Egyptian astronomical texts describe only Sirius A (Sothis). There is no indication ancient Egypt knew Sirius was a binary system or knew any properties of an invisible companion.
