How did the ancient Egyptians choreograph dances about Osiris?

The ancient Egyptians worshipped Osiris very much and regarded it as the main content of religious dance. Dance is usually performed in spring sowing season and autumn harvest season. During the performance, a man wore a hat made by himself and dressed up as the god of resurrection; Other men wear "eagle" headdress to dress up the soul of adults, and the dance movements are relatively simple, mostly upper limbs, in order to pray for Osiris to give immortal souls to the dead. The dance atmosphere is relaxed, joyful and festive, which shows the plot that the "soul" greets the resurrected God with joy.
