Idyll XI, otherwise known as Bucolic poem 11, was written by Theocritus in dactylic hexameter. Its main character, the Cyclops Polyphemus, has appeared in other works of literature such as Homer's Odyssey, and Theocritus' Idyll VI. Idyll XI is written in the Doric dialect of ancient Greek. In that dialect, the Cyclops' name is "Polyphamos." The more familiar "Polyphemos" is the form in which he is known in the Odyssey, which is written in the Ionic dialect. Source: Wikipedia (en)
