The story is an addition and expansion of the account of the Biblical Magi, recounted in the Gospel of Matthew in the New Testament.[3] It tells about a "fourth" wise man (accepting the tradition that the Magi numbered three), a priest of the Magi named Artaban, one of the Medes from Persia. Like the other Magi, he sees signs in the heavens proclaiming that a King had been born among the Jews. Like them, he sets out to see the newborn ruler, carrying treasures to give as gifts to the child - a sapphire, a ruby, and a "pearl of great price". However, he stops along the way to help a dying man, which makes him late to meet with the caravan of the other three wise men. Because he missed the caravan, and he can't cross the desert with only a horse, he is forced to sell one of his treasures in order to buy the camels and supplies necessary for the trip. He then commences his journey but arrives in Bethlehem too late to see the child, whose parents have fled to Egypt. He saves the life of a child at the price of another of his treasures.
