Do you know the origins of this painting?

Do you know where this painting is from? Its date? provenance? Is this depicting the Father, the Son, and the Holy Spirit (the female in the middle)?

Update: A reader (alias "Mac") has left these links for which I am very grateful. Now I need to track down this fresco. I'm assuming it is in a church? Any more leads?

I believe you will find the answer at this link (in German I think)
And at another link in Hungarian:

The Holy Ghost as a Woman
