• Pippin Arnulf Héristal - protagonist of the story; he is an amateur astronomer whose bloodline traces back to
King Pippin II and to
Charlemagne. He later becomes the
King of France. • Marie, Pippin's wife - a practical, buxom woman who becomes
Queen of France in a down-to-earth fashion. She likens managing the kingdom to managing a home. • Clotilde, Pippin's daughter - a best-selling author, inspiration for a religious movement, intellectual prodigy, and
Crown Princess, all by the age of twenty. She is a stereotypical youth, clumsy and frivolous. • Charles Martel - Pippin's uncle, an art and antique dealer who shares a name with the
historical figure, an ancient member of his family. He often advises Pippin on tough situations. • Sister Hyacinthe (née Suzanne Lescault) - a former
cabaret performer-turned-nun who provides sage advice to Marie and Pippin. • Tod Johnson - a young American traveling in Europe who becomes involved with Clotilde; heir to a large fortune from his father, H. W. Johnson, the "Egg King of
Petaluma, California". He introduces Pippin to the American way of
politics. ==References==
