[Muses'] gifts of song, dance, and joy helped the gods and mankind to forget their troubles and inspired musicians and writers to reach ever greater artistic and intellectual heights.

For Art Thursday, we have the heavenly muse Urania, goddess of astronomy. It's interesting, since the muses are the goddesses of the arts, that astronomy was considered one of the arts (and history was as well). Urania is generally shown looking up, sometimes shown with a halo of stars. I knew Apollo (the "Muse-leader") was the Sun God but I hadn't realized that he was also the god of Eloquence. You can see in the below painting what an effect he is having, not only on Urania but on the swans.
