Garnier, Etienne-Barthélémy – Entrée de Napoléon et de Marie-Louise dans le jardin des Tuileries, 2 avril 1810 Château de Versailles

The picture has something of this: many, people, group, cavalry, seated, vehicle, crowd, daylight, group together, transportation system, man, festival, woman, soldier, city, parade, war, military.
Perhaps it’s a painting of a large crowd of people and horses in a park with a fountain in the middle of the picture.
