Scarab seal

"Ancient Egyptian scarabs were popular amulets in ancient Egypt. According to ancient Egyptian myths, the sun  rolls across the sky each day and transforms bodies and souls. Modeled upon the Scarabaeidae family dung beetle, which rolls dung into a ball for the purposes of eating and laying eggs that are later transformed into larva, the scarab was seen as an earthly symbol of this heavenly cycle. This came to be iconographic, and ideological symbols were incorporated into Ancient Egyptian society."
