The First Distribution of Crosses of the Legion of Honour in the Church of the Invalides, 14th July 1804 Jean Baptiste Debret (1768-1848)

The picture has something of this: people, group, many, ceremony, man, music, dancer, wear, woman, festival, costume, temple, dancing, god, celebration, theater.
Perhaps it’s a painting of a group of people standing in front of a crowd of men and women, all dressed in historical clothing, in a palace setting.
