About this source

What it is

This engraving appeared in John Louis Emil Dreyer's 1890 biography Tycho Brahe: a picture of scientific life and work in the sixteenth century. It depicts Uraniborg, the observatory Tycho built on his island, shown from above with domed buildings, instruments and tiny figures of observers.

Why it matters

Uraniborg was one of the most advanced research centers of its time, built and run by Tycho Brahe to make precise astronomical observations without telescopes. This later illustration, created by astronomer Dreyer long after Tycho's death, helps modern readers imagine the scale and organization of Tycho's scientific operation.

Look closer

  • What does the layout of the buildings tell you about how organized and funded this research center was?
  • Why do you think Dreyer included this image in a biography written centuries later?
  • What parts of daily scientific work might this picture not show?
