Rinaldo and Armida Giovanni Battista Tiepolo (1696-1770)

The picture has something of this: people, water, woman, seashore, veil, wear, reclining, recreation, facial expression, man, beach, group, sea, daylight.
Perhaps it’s a painting of a group of people standing next to each other in front of a rocky landscape with trees and a large pillar in the middle of the painting.
