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.
All characters in a story are either dynamic or static. A static character is one who doesn't undergo any significant change in character, personality or perspective over the course of a story. A dynamic character, in contrast, undergoes a major transition in one or more of these ways.
