Seated at a table, a well-dressed medical alchemist examines a flask he holds aloft. Opposite, a young man and woman anxiously await his diagnosis. Urinoscopy, or the visual examination of urine for diagnosis, was a common practice during the 16th and 17th centuries, thought to reveal numerous health conditions. The alchemist's chamber is spacious and well-lit by large open windows at left. Rows of glassware and vessels beside him indicate his many medicinal preparations, tonics, or cures.
