Fra Angelico painted the Adoration of the Magi numerous times. 

          This scene appears, for example, on:
                 - The second of the four Masi reliquaries
                 - The Silver Chest (panel 1, row 2);
                 - The central predella scene of the Linaiuoli Tabernacle;
                 - The fresco of Cell 39 in the San Marco Convent

          He also depicted the Adoration of the Magi in the two beautiful, independent works below.
