The Tradition of the Galette des Rois ("Cake of the Kings") originated with the Romans. At the feast dedicated to the God Saturn the Romans celebrated by sharing a large round cake, golden like the sun.
By the end of the 4th Century such pagan festivals were
forbidden and were replaced with a religious one. The Magi:
Melchior, Balthazar and Caspar were elevated to the rank of "kings"
and the "Feast of the Kings" was celebrated on the 6th
The Tradition of the Cake with a "feve" or bean in, comes from the Chapter of Canons at Besancon. In the 14th Century they would put a "feve" in some bread, and whoever got the "feve" would become the new head of the Chapter. The "feve" is a symbol of fertility and is also a recollection of the gifts offered to the Son of God by the Magi. The oak leaf crown (the leaves that used to adorn the crowns of French Kings and Emperors) is worn by the finder of the "feve" in the "Galette des Rois".
Cassandra designed the Epiphany bracelet telling the story of the Wise Men: composed of "cups" of Myrrh and Frankincense and a chest of Gold, with each section being linked by a triple link from which a guiding star, "feves" in the form of crowns (and other charms) can be attached.
Cassandra saw the symbolism of the Three Kings being like godparents, bearing gifts to a new born child and led by the star. Her own bracelets (often worn as a necklace) have silhouettes of her children, Alice Letters of their initials and Epiphany crowns hanging from them!
