Art history has historically been understood as the academic study of objects of art in their historical development and stylistic contexts, i.e. genre, design, format, and style. This includes the "major" arts of painting, sculpture, and architecture as well as the "minor" arts of ceramics, furniture, and other decorative objects. ~Wikipedia

The digital age has made the pursuit of art history, both as a vocation and an avocation, much more exciting and productive. Assuming you are not already familiar with the painting shown here, you should be able  to determine the artist, the time period, and the meaning of the painting in less than ten minutes.
