This complicated design is associated with the Olympian God of Fire: Hephaestus, God of fire, metalworking, stone masonry, forges, the art of sculpture and blacksmiths. As a smithing god, Hephaestus made all the weapons of the gods in Olympus.
According to Homer's epics, the Iliad and the Odyssey, he was the son of Zeus and Hera.
According to one account, after Hephaestus was born, Hera threw him from Olympus because he was crippled; he fell into the ocean and was raised by Thetis (a sea nymph) and Eurynome (a Titan goddess).
Another myth has it that he once tried to protect his mother from Zeus' advances and as a result, the father of the Gods flung him down from Olympus, which caused his physical disability; he fell on the island of Lemnos where he became a master craftsman. . He was later accepted back to Olympus, and became the Craftsman of the Gods, creating majestic armors, shields and weapons.
The Greek letter Omega in the center of the design is used as a symbol of the last, best, or final nature of something.
