Galeos was a Greek slaver who lived in Thebes, Boeotia during the 5th century BC. During the Peloponnesian War, he sold slaves from Melanippos' Camp on Lake Copais, and he was wounded when two bears attacked his hunting party near the Snake Head Rock. He was rescued by the mercenary Kassandra at the behest of the physician Hippocrates, who was unaware of the surviving hunter's identity; when Kassandra took Galeos back to Hippocrates for treatment, Hippocrates hesitated to treat Galeos and risk him abusing his slaves until Kassandra volunteered to free Galeos' slaves from his camp. Hippocrates reluctantly nursed Galeos back to health, convinced that his and Kassandra's rescue of Galeos might convince the slaver to change his ways, and that only the gods could take or give life.
