Summary

Description Tycho Brahe's mural quadrant in Uranienborg (Uraniborg). The quadrant (radius c. 194cm) was made from brass and was affixed to a wall that was oriented precisely north-south. The observer (right) views a star through the opposite opening (upper left) to determine the star's altitude as it passes through the meridian. An assistant (lower right) reads the time off a clock and another one (lower left) records the measurements. The area above the quadrant is filled with a mural painting showing several other of Brahe's instruments. See Brahe's original description of the instrument.

This is a faithful photographic reproduction of a two-dimensional, public domain work of art. The work of art itself is in the public domain for the following reason:
Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 100 years or fewer.


This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain".
This photographic reproduction is therefore also considered to be in the public domain in the United States. In other jurisdictions, re-use of this content may be restricted; see Reuse of PD-Art photographs for details.
