Lucas Cranasch the Elder (c. 1472- 1553) – The Crucifixion Kobenhavn (SMK) National Gallery of Denmark

The picture has something of this: people, saint, group, cavalry, Renaissance, book, god, cross, man, woman, baby, virgin, holy, religious.
Perhaps it’s a painting of a crucifix with a group of people in the foreground and a man on the cross in the middle of the painting.
