Queen Zenobia Addressing Her Soldiers Giovanni Battista Tiepolo (1696-1770)

The picture has something of this: people, group, cavalry, man, weapon, sword, war, wear, skirmish, military, many, soldier, woman, seated, veil.
Perhaps it’s a painting of a man standing in front of a crowd of people holding flags and pointing to a statue of a woman on top of a pedestal.
