An Astronomer

An Astronomer is a 1652 painting by Ferdinand Bol, a student of Rembrandt. It is now in the National Gallery, London, to which it was donated by E.A.Bennett in 1862.
It shows an astronomer at a table, on which are terrestrial and celestial globes on the table. The work also draws on the themes of "Melencolia I", an engraving by Dürer.
