According to Greek Mythology, Galatea was a Nymph of the sea and carried about on a chariot pulled by two dolphins.
Cherubs flew above her.
The famous artist, Raphael, depicted the scene and many artists have subsequently executed their versions.

This canvas is 26 x 31 and has a masonite backing.
It is obvious that over the course of time, it has been touched up in several places by a less skilled artist.
