In Roman mythology, the story of Hercules and Cacus highlights the hero's strength and bravery. Cacus was a fire-breathing giant who lived in a cave near Rome. He stole cattle from Hercules and hid them in his lair, hoping to avoid detection. When Hercules discovered the theft, he followed the cattle's lowing sounds to Cacus' cave. A fierce battle ensued, and Hercules ultimately defeated the giant, freeing his stolen cattle. This tale emphasizes the themes of heroism and the triumph of good over evil in ancient mythology.
