Characters

Most of the characters of the book are named after math terms, such as Sir Cumference (circumference).

Sir Cumference

Sir Cumference is a knight in the kingdom of Camelot. He is married to Lady Di of Ameter, with whom he has a son named Radius.

Di of Ameter

Di of Ameter is the wife of Sir Cumference. In the first book, she came up with the shapes of the table (parallelogram, square, etc.) and in Sir Cumference and the Dragon of Pi, she stayed with Sir Cumference when he was transformed into a dragon.

Radius

Radius is the son of Di of Ameter and Sir Cumference. He has a friend named Vertex in Sir Cumference and the Sword in the Cone, and plays an important role in both Sir Cumference and the Dragon of Pi and The Sword in the Cone first by turning his father to a dragon and back, and later assisting Vertex in becoming king. He is the focus of Sir Cumference and the Great Knight of Angleland, in which he becomes a knight after rescuing King Lell and his pair of dragons.

Vertex

Vertex is the best friend of Radius. Sir Cumference and Radius agree Vertex should be the heir to the throne.
