Parnassus (1497) Andrea Mantegna (1431-1506)

The picture has something of this: group, people, veil, mammal, Renaissance, woman, god, man, wear, allegory, kneeling, cavalry, lithograph, position.
Perhaps it’s a painting of a group of people standing in front of a cave with a man on top of a horse and a woman on the other side of the cave.
