Another wonderful copyright free illustration from Roman Mythology of Apollo dancing with the Muses. From the book in which this image appears,
“In general they were considered as the tutelar goddesses of sacred festivals and banquets, and the patronesses of polite and useful arts. They supported virtue in distress, and preserved worthy actions from oblivion. Homer calls them superintendents and correctors of manners. In respect to the sciences, these sisters had each their separate province; though poetry seemed more immediately under their united protection.”
It appeared in Roman Antiquities, And Ancient Mythology for Classical Schools written by Charles K. Dillaway and published in 1833. No llustrator was identified.
