Astronomical Ceilings
Astronomical Ceilings
The Foreleg is the only one that exists in the modern sky and is called the Plough or Big Dipper
However, its possition has changed
The stars are divided into 2 groups
Stars in the north who don't rise or set (circumpolar group)
Stars in the south who rise and set (decans)
The representation of circupolar group & number of figures change
However, 3 characters don't change (the foreleg, hippopotamus & the mooring post)
The circumpolar group is situated in the northern half of the ceiling
They don't rise or set but rotate around the north celestial pole
Circumpolar group is a group of stars or constelation with particular behavior when observed from Egypt
Planets & decans occupy the southern part of the ceiling
The decans are interpersed with two groups of planets
3 plantes have orbits outside the earth
Between the ordinary and triangle dicans (Mars, Jupiter & Saturn)
2 planets whose orbit is inside that of the earth, the morning & evening stars
Follow the triangle decans (Mercury and Vinus)
The calendar is not present in the ceilings but the stars and their order are
The diagonal star tables record stars performing a particular action in order throughout the year
The 1st major element is a list of stars known as decans
The number of decans change but their order doesn't change
they are divided into 2 groups named Ordinary & triangle decans
11 or 12 triangle decans
there are 36 ordinary decans
How they decorated the ceilings
By the new kingdom, they used more representative designs
In the earlier times, they painted the ceiling blue and painted yellow five pointed stars
The ancient Egyptians tryed to keep the design of the ceilings as close as possible to the sky
