en.wikipedia.org/wiki/The_Astronomer_(Vermeer)
. . . . In ‘The Astronomer’ a large astrolabe, which also measures angles of altitude in the heavens, rets against the celestial globe on the cabinet is a chart that is thought to be a celestial planisphere, and on the table in front of the astronomer is a book open to an illustration of the cartwheel astrolabe, which was invented by the author, Adrian Metius. As explained by Welu, Metius’s basic text on astronomy and geography (Institutiones Astronomicae, Geographicae, Amsterdama 1621) offered ‘short and clear instruction for the art of navigation’ (according to Metius himself) and is open to the first two pages of Book III, ‘On the Investigation or Observation of the Stars.’
