Portrait of a Gardener and Horn Player in the Household of the Emperor Francis I Albert Schindler (1805-1861)

The picture has something of this: people, god, man, facial hair, music, instrument, veil, temple, harp, worship, culture, position, sculpture.
Perhaps it’s a painting of a man sitting on a window sill holding a musical instrument in his right hand and a potted plant in the other hand.
