The first paintings for the Studiolo were completed by Andrea Mantegna, and he appears to have started this painting, but it was completed by Costa between 1506 - 1511, after Mantegna's death, when Costa had been named court painter.
To the left of the foreground tree, a sitting Comus, the ruler of a land of bacchanals, with his head tilted looks at Venus.
In the center, Dionysus strokes the hair of a drunken maiden, identified as Nicaea.
[2] Meanwhile, to the right of an elaborate arch, Janus bifrons and Hermes shoo away poorly clothed figures from the enjoyments of Comus.
[3] The elaborate painting may have a moral justifying some of the virtues of reveling, or perhaps it is a melancholic work which exalts as virtuous, only Nicaea, the one character oblivious to the orgies around her.
