'Zodiac sign Pisces at Dendera.'
A fish on either side of a pond makes up the zodiac sign Pisces on the astronomical ceiling in the outer hypostyle hall of the Hathor Temple at Dendera. The ceiling consists of seven separate strips but here we are looking at a detail of the upper register of the EASTERNMOST STRIP.
There are six zodiac signs depicted in the entire easternmost strip and the other six can be found on the westernmost ceiling strip of the hall. These signs are of Babylonic-Greek origin and are not found in Egypt before it was conquered by Alexander the Great in 332 BC.
The standing women to the left and the right of the fish are the goddesses of the 5th and 4th hour of the night.
The disk with a god holding a small pig by a hind foot is interpreted by some scholars as the sun being eclipsed, but this can't be proven.
The falcon-headed god on the right is the planet Mars (called 'Horus-the-Red). Other Egyptian astronomical texts mention that the god "travels backwards', which is undoubtedly an allusion to the retrograde movement of Mars. Of course other planets display this movement also, but maybe the Egyptians found it particularly striking in Mars.
