Menzel, Adolf von. Departure knights with drawn swords. 1829 Hermitage ~ part 08

The picture has something of this: cavalry, people, group, festival, mammal, wear, sword, culture, many, carriage, costume, chariot, veil, ancient, parade.
Perhaps it’s a painting of a group of men on horses in front of a building with a crowd of people standing on the side of the street.
