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 whose significance is disputed. The Magi are usually shown as the same age until about this period, but then the idea of depicting the three ages of man is introduced: a particularly beautiful example is seen on the façade of the cathedral of Orvieto. Occasionally from the 12th century, and very often in Northern Europe from the 15th, the Magi are also made to represent the three known parts of the world: Balthasar is very commonly cast as a young African or Moor, and old Caspar is given Oriental features or, more often, dress. Melchior represents Europe and middle age.
