Aelbert Cuyp – Equestrian Portrait of Cornelis (1639–1680) and Michiel Pompe van Meerdervoort (1638–1653) with Their Tutor and Coachman (Starting for the Hunt) Metropolitan Museum: part 1

The picture has something of this: people, group, woman, wear, cavalry, man, mammal, child, seated, recreation, girl, two, lid, weapon, boy, war, friendship, lifestyle, leisure.
Perhaps it’s a painting of a group of people riding on the backs of horses next to a dog and a man on a horse with a dog in the foreground.
