Ucello, Paolo (or Uccello, Italian, 1395-1475)3 Paolo Uccello

The picture has something of this: people, group, cavalry, tree, mammal, competition, man, group together, many, recreation, military, uniform, vehicle, wear, weapon, seated, action, woman, war.
Perhaps it’s a painting of a group of men on horses and dogs in a wooded area with a dog laying on the ground in the foreground of the painting.
