Dendera and the decans
Egyptian zodiac signs
Did ancient Egypt have a zodiac? What the Dendera zodiac shows, what the 36 decans were, and where the popular “Egyptian zodiac signs” come from.
The short answer
Ancient Egypt did not originally use the twelve-sign zodiac. The zodiac arrived from Mesopotamia via the Greeks in the Ptolemaic period (after 332 BCE). Egypt’s own contribution was the system of 36 decans, star groups used to tell time at night.
The Dendera zodiac
The most famous Egyptian zodiac is a sandstone ceiling relief from the Temple of Hathor at Dendera, carved around 50 BCE. It combines the Greco-Babylonian twelve signs (a ram, bull, twins, crab and so on) with Egyptian decans and deities. The original was removed to Paris in 1821–22 and is now in the Louvre; a cast is in the temple today.
The 36 decans
From at least 2100 BCE, Egyptian coffin lids show tables of decans: groups of stars that rose about ten days apart, used as a star clock. Later, astrologers split each zodiac sign into three 10° decans, which is where modern decan astrology comes from.
The popular “Egyptian zodiac”
Websites often list twelve Egyptian signs named after gods (Nile, Amun-Ra, Mut, Geb, Osiris and so on) with scattered date ranges. We have not found any ancient source for this chart; it appears to be a modern creation, so we do not reproduce it as a tradition.
Frequently asked questions
What is my Egyptian zodiac sign?
There is no authentic ancient Egyptian birth-sign system. The Dendera zodiac used the same twelve signs as Greek astrology, so your Western sign is the closest historical equivalent.
