Adoration of the Magi (Fra Angelico and Filippo Lippi) interest in both the subject and the form. The Magi had been the key Medici devotion for decades, apparently beginning with the papacy of Antipope John XXIII (1410–1415) when they had become the main bankers of the Papacy, or at least those parts John controlled. The Medici belonged to the "Compagnia de' Magi", a Florentine confraternity based at the San Marco complex just by the Medici Palace, both of which Cosimo de' Medici rebuilt a few years before the tondo was painted. An annual procession on the feast of the Epiphany on January 6 was organized by the confraternity, and
Adoration of the Magi the "Dream of the Magi". The usefulness of the subject to the Church and the technical challenges involved in representing it have made the Adoration of the Magi a favorite subject of Christian art: chiefly painting, but also sculpture and even music (as in Gian-Carlo Menotti's opera "Amahl and the Night Visitors"). The subject matter is also found in stained glass. The first figural stained glass window made in the United States is the "Adoration of the Magi" window located at Christ Church, Pelham, New York and designed in 1843 by the founder and first rector's son, William Jay Bolton.
