An Astronomer with a Globe

Gerrit Dou, also known as Gerard Douw or Dow, was a Dutch Golden Age painter, whose small, highly polished paintings are typical of the Leiden fijnschilders. He specialised in genre scenes and is noted for his trompe-l'œil "niche" paintings and candlelit night-scenes with strong chiaroscuro. He was a student of Rembrandt.
