The Coronation of William I at Konigsberg in 1861 Adolph von Menzel (1815-1905)

The picture has something of this: people, many, group, ceremony, indoors, gold, temple, god, church, worship, religious, chandelier, candle, communion table, monastery.
Perhaps it’s a painting of a crowd of people standing around a stage with a man in a suit and tie standing next to a woman in a white dress.
