Cronos dreams of what he accomplish as king. His ambition overrides his loyalty to his father and allows him to plot against him with his mother, Gaia.
There is a theme, repeated many times in Greek myth, of the son rising up to overthrow the father and take his place. Cronos and Uranus, Zeus and Cronos, and then Zeus does horrible things because he fears his own children. What does this tell us about how the ancient Greeks viewed their own children? Did they work to see them succeed in life, as we do today, or did they fear them?
Did they just understand that life is short and in the end, the son replaces the father?
