Astronomer by Candlelight, late 1650s. Additional Info: In an arched, window-like opening, an astronomer works late into the night. Concentrating, he reads an astronomical treatise and measures the distance between two points on a celestial globe. The candle he holds provides the only source of light; it illuminates his face, the book, the precious globe, the beaker of water, and his hourglass.
