The Parnassus was the first picture painted by Mantegna for Isabella d'Este's studiolo (cabinet) in the Ducal Palace of Mantua.
Together with the other paintings in the studiolo, it was given to Cardinal Richelieu by Duke Charles I of Mantua in 1627, entering the royal collections with Louis XIV of France.
The traditional interpretation of the work is based on a late 15th-century poem by Battista Fiera, which identified it as a representation of Mount Parnassus, culminating in the allegory of Isabella as Venus and Francesco II Gonzaga as Mars.
The latter is still holding the arch, and has a blowpipe which aims at the genitals of Vulcan, Venus' husband, portrayed in his workshop in a grotto.
The touch of Pegasus's hoof (right) can generate the spring which fed the falls of Mount Helicon, which can be seen in the background.
