Shu was a god that the ancient Egyptians believed in. He was a really important god because he was in charge of the air and everything that lived and breathed in it, like people, animals, and plants.
Shu was usually shown as a man with feathers on his head, holding up the sky with his strong arms. The ancient Egyptians believed that the sky was like a big box that covered the earth and was held up by Shu.
