Concert of Apollo and the Muses on Mount Helicon (1565). Maerten van Heemskerck (Dutch, 1498-1574). Oil on panel. Chrysler Museum of Art.
Heemskerck envisions Helicon as an idyllic, tree-shaded paradise, an antique pleasure garden set with statues and littered with books and musical instruments. He alludes to the creation of Hippocrene in an ingenious way, portraying Pegasus as a monumental bronze statue and the fountain as a spray of water issuing from its strut. The two male figures standing at right are poets who have received inspiration and been crowned with laurel.
