Is the cyclops, Polyphemus, written of in Homer's Odyssey the exact same character as the Polyphemus from the Argonautica?
I am referring to Apollonius of Rhodes' "The Voyage of Argo", or more commonly referred to as "Jason and the Argonauts".
No, they are quite distinct. All they share is the same name. Polyphemus the cyclops, distinguished by his gigantic appearance and single eye, is the son of Poisedon, god of the sea, whereas Polyphemus in Jason and the Argonauts is an ordinary man, who later became a king.
