Those scenes were interiors with similar windows and furnishings populated by a young woman. Superficially, this is similar to a number of the known works by the famed Dutch artist Johannes (Jan) Vermeer where there was a window towards the left side of the painting, one or a few human subjects (usually female), and varying room décor.
Holsøe painted other subjects -- often different interiors -- but I thought it would be fun to present a set of his paintings that portray essentially the same sort of thing. Besides paned windows, some on French doors, nearly every painting contains a tall, narrow mirror. Titles are omitted in the Gallery below.
