The personification of the art of painting, supported by Cardinal Girolamo Buonvisi, arrives on a triumphal car at Mount Parnassus where she is greeted by the muses. Etching by P. Testa, ca. 1642.

In the centre, a horse-drawn carriage proceeds under a rainbow created by rays of the sun shining on Iris ("Arcum meretur"). The carriage holds Pictura, the personification of painting, and takes her towards Mount Parnassus and Mount Helicon. Pictura is painting a shield with the arms (as cardinal) of Girolamo Buonvisi. The three Graces crown her with a laurel wreath. On the left are shown actions and expressions which have been recorded with the aid of painting ("Affectus exprimit"), such as Laocoon being strangled by a snake, Pan, Flora, Samson fighting a lion, and Adam and Eve. On the right the ancient poets prepare to descend from Parnassus to greet her, and the Muses stand at the foot of the mountain ("Parnaso triumphat"). On Mount Helicon, Pegasus is creating the spring Hippocrene, from which water flows down through a pool with swans to a lower pool, where a river god distributes it into two streams (presumably the Serchio, in Lucca, and the Tiber, in Rome)
