Peter Pevensie is a fictional character in C. S. Lewis's The Chronicles of Narnia book series. Peter appears in three of the seven books; as a child and a principal character in The Lion, the Witch and the Wardrobe and Prince Caspian, and as an adult in The Last Battle. He is only mentioned in The Horse and His Boy in which he is away on the northern frontier fighting giants and in The Voyage of the Dawn Treader in which he is studying under the tutelage of Professor Kirke. In Disney's live-action films, The Lion, the Witch and the Wardrobe, Peter is portrayed by English actor William Moseley. Noah Huntley portrays an older Peter at the end of the first film. Peter is the eldest of the four Pevensie children and shares his adventures in Narnia with his sisters Susan and Lucy and with his brother Edmund. Peter's reign in Narnia was a Tetrarchy (Greek: "leadership of four"), and as High King Peter the Magnificent, he had supreme authority over all subsequent Narnian monarchs. Peter is illustrated by Pauline Baynes in the original novels with dark hair, but there are no specific descriptions of his hair or eye colour or complexion by Lewis. Name An early draft of The Lion begins, "This book is about four children whose names were Ann, Martin, Rose, and Peter. But it is most about Peter who was the youngest." Peter is the only name that makes it into the final work, but as the oldest child instead of the youngest. Pevensey, on the southeast coast of England, is the site of a medieval castle that figures importantly in British history at several points. In Rudyard Kipling's Puck of Pook's Hill (1907) at least one of the characters refers to Pevensey as "England's Gate", which the celebrated wardrobe in Lewis's books quite literally becomes. The surname "Pevensie" does not actually appear in the Chronicles until the third published book, The Voyage of the Dawn Treader. Biography Prior story Peter was born in 1927 and is 13 years old when he appears in The Lion, the Witch and the Wardrobe.
