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.
A static character does not. A round character is fully developed so that the reader has a good picture of their looks and personality. A flat character, or stock character, is like a filler - somebody who plays a role but has no personality that is pertinent to the story, like storekeeper, or police officer..
