The Dendera Zodiac is a big round thing with pictures on it that ancient Egyptians made a long, long time ago. It is like a giant clock that shows the stars and planets that they believed controlled their lives. The pictures on it look like animals and people, and they are arranged in a circle with a line going through the middle.
Imagine you have a toy car with four wheels. The wheels all turn together and they help the car go in the right direction. The Dendera Zodiac is like that toy car with its wheels. The pictures on it show 12 different groups of stars - one for each month of the year - and they help people know what time of year it is and what they should be doing.
The Dendera Zodiac is special because it is one of the oldest known representations of the constellations. It also shows how people a long, long time ago used the stars to tell time and know when to plant crops or hold certain celebrations. It helps us better understand how ancient people thought about the world around them and the important role the stars played in their daily lives.
