In Egyptian mythology Shu was the god of air, wind and the serenity associated with such elements. In the Heliopolitan creation myth Shu separates the sky from the Earth, initiating the creation of life. His kneeling representation, as demonstrated on this amulet, alludes to this myth. The sun disc seen between the raised arms represents the vast sky. He was also commonly depicted wearing an ostrich feather and was often associated with Ma’at (truth).
