Issue 19 Autumn 2009 BULLETIN Books and the Sky HIS dramatic painting shows Tan Astronomer by Candlelight by the Dutch artist Gerrit Dou (1613-75) who was a pupil of Rembrandt. It dates from the late 1650s. Dou was famous for his mastery of chiaroscuro and the effects of artificial light. These techniques are deployed here to great effect. Late at night an astronomer studies a book while using dividers to measure an angular sepa- ration on a celestial globe. The happy connection between books and astronomy was explored in the meeting Books And The Sky which was held at the Institute of Astronomy, Cambridge during April this year. It was organised to celebrate the outstanding achieve- ments in astronomical his- tory and scholarship of SHA member Dr David Dewhirst. A report appears inside. Some of the other items continue the bibliographic theme, and we also carry all the usual material. Astronomer by Candlelight is held by the J. Paul Getty Museum, Los Angeles.
