Dogon People -- Ancient Greek Knowledge of Sirius

Sirius in Greek Culture

Sirius held a specific and important place in ancient Greek astronomical and agricultural knowledge. The Greeks called it Seirios (burning, scorching) -- a name reflecting both its brilliance and its association with the hottest part of summer.

Key elements of Greek Sirius knowledge:

Homer: In the Iliad (c. 8th century BC), Homer describes Sirius as "the star of late summer who, brilliant as he is, is reckoned a sign of evil, and brings on the great fever for unfortunate mortals." The association of Sirius's heliacal rising with the "Dog Days" of summer -- the hottest and most unhealthy period of the year -- is already present in Homer.

Hesiod: In Works and Days (c. 700 BC), Hesiod gives specific agricultural instructions tied to Sirius's rising: when Sirius appears in the night sky, certain agricultural tasks should be completed. This reflects practical agricultural astronomy -- using stellar rising times as calendar markers -- that was common across the ancient Mediterranean.

Aratus of Soli: In the Phaenomena (c. 270 BC), Aratus gives extensive discussion of Sirius, its colour, its brilliance, and its agricultural and meteorological significance. Aratus specifically notes Sirius's colour changes -- a phenomenon that has been observed by many cultures and is caused by atmospheric refraction affecting bright stars near the horizon.

What Ancient Greeks Did NOT Know

Ancient Greek astronomical knowledge of Sirius, while sophisticated in terms of calendar use and meteorological association, did not include:

• The existence of any companion star (Sirius B)
• Any binary star knowledge whatsoever (the concept of binary stars was not developed until the 18th-19th centuries CE)
• Any precise orbital measurement

The Greeks knew Sirius as the brightest and most practically important star. They did not know about its invisible companion.

The Transmission Question

Even if the Dogon's astronomical knowledge derived from ancient Mediterranean sources through trans-Saharan trade rather than from extraterrestrial contact or Griaule contamination, that Mediterranean transmission would have occurred before the existence of Sirius B knowledge in any Mediterranean tradition -- because Sirius B was unknown in the ancient Mediterranean.

The trans-Saharan diffusion hypothesis can only explain the Dogon's general reverence for Sirius and their use of it as a cosmological anchor. It cannot explain the specific properties attributed to Po Tolo.
