This panel was executed in gold and tempera, a medium in which pigments are suspended in egg yolk. This technique was commonly used before oil painting became popular later in the fifteenth century. The Master of the Imola Triptych was active in Emilia (region of Bologna) and Ferrara during the first half of the fifteenth century. His art reflects something of the colour vivacity and linear animation of Fabriano and Pisanello. Lombard miniatures and artists working in Bologna from 1420 to 1430 also influenced his style. Inspired by the International Gothic style, ornately detailed and highly patterned, the Master employed rich colourism. His works are very rarely found outside of northern Italy; this example is the only one in North America.
