This is an example of Italian Rococo art. It is a painting by Giovanni Battista Tiepolo (1696-1770), and is found in the Metropolitan Museum of Art. The medium is oil on canvas.
I was curious to look into Italian Rococo art on Wikipedia, since Rococo style and era in art seems most typical of France. I like this painting since it seems to use themes of mythology to describe the planets and the continents of Earth, and since it depicts an early understanding of our world and our solar system.
