Caspar David Friedrich was a prolific artist who produced more than 500 attributed works. In line with the Romantic ideals of his time, he intended his paintings to function as pure aesthetic statements, so he was cautious that the titles given to his work were not overly descriptive or evocative. It is likely that some of today's more literal titles, such as "The Stages of Life", were not given by the artist himself, but were instead adopted during one of the revivals of interest in Friedrich. Complications arise when dating Caspar David Friedrich Paintings, in part because he often did not directly name or date his canvases.
