After the punishment of Telphusa for her deceit in giving him no warning of the dragoness at Pytho, Apollo, in the form of a dolphin, brings certain Cretan shipmen to Delphi to be his priests; and the hymn ends with a charge to these men to behave orderly and righteously.
A dynamic character is a character who changes throughout the course of a story as a result of the conflicts they encounter on their journey. Some dynamic characters learn a lesson, like Harry Potter did in Harry Potter and the Chamber of Secrets.
Here's a very common mistake: while characters are often round and dynamic, that does not mean these two terms mean the same thing. The former refers to a character's complexity, while the latter refers to a character's development over time. Students also make this mistake with flat and static characters.
