Pauwels van Hillegaert – The Princes of Orange and their Families on Horseback, Riding Out from The Buitenhof, The Hague Mauritshuis

The picture has something of this: cavalry, people, group, mammal, many, man, woman, seated, carriage, outdoors, crowd, transportation system, recreation, child, tourist.
Perhaps it’s a painting of a group of people on horses in front of a large building with a fountain in the middle of the picture and a dog in the foreground.
