This dragon has a head of 100 and never sleeps. The 1 1 adventure of Heracles, the queen of the gods, is to take out three golden apples from the orchard guarded by the dragon. When Hercules found the orchard, he was blocked by the dragon's flame. With his intelligence, he won the trust of Atlas, the Hercules who was atoning for his sins and carrying the celestial sphere on his shoulders.
