Help me identify this painting?

I went to SAM a couple weeks ago and saw a painting that I fell in love with, however I don't remember the name or the artist. It was a painting (I believe oil on canvas) of Neptune in the center with a woman below him. She is naked and on a fish. On the left side of the painting are the winds and the right side there is cherubs reining in horses. It's similar to the creation of adam. I was directed to The Triumph of Neptune, but it isn't it. Any help would be awesome, I would love to know the name of this painting
