Giovanni Benedetto Castiglione (1609-1664) – Meeting of Abraham and Melchizedek Part 3 Louvre

The picture has something of this: cavalry, group, people, many, mammal, herder, seated, skirmish, veil, interaction, man, livestock, bird.
Perhaps it’s a painting of a group of people riding on the backs of horses in front of a crowd of men and women, all with helmets on their backs.
