Encyclopdia Britannica states: "according to Western church tradition, Balthasar is often represented as a king of Arabia, Melchior as a king of Persia, and Gaspar as a king of India." These names apparently derive from a Greek manuscript probably composed in Alexandria around 500, and which has been translated into Latin with the title Excerpta Latina Barbari. Another Greek document from the 8th century, of presumed Irish origin and translated into Latin with the title Collectanea et Flores, continues the tradition of three kings and their names and gives additional details.
