Projet de fontaine : Naïade et putti Jacques De LaJoüe (1687-1761)

The picture has something of this: sculpture, church, ancient, architecture, decoration, baroque, culture, temple, castle, statue, gold, symbol, building, ornate, artistic, monument.
Perhaps it’s a painting of a woman sitting in a room with a fountain in front of her and a man standing on the other side of the room looking at her.
