Andromeda Chained to the Rock by the Nereids 1840 Theodore Chasseriau (1819-1856)

The picture has something of this: nude, woman, people, sculpture, baroque, Renaissance, man, saint, love, statue, group, god, museum, two, cherub, cupid.
Perhaps it’s a painting of a group of people in a rocky area with a woman in the foreground and a man on the other side of the painting.
