delivered. Tycho, of course, set off at once and had an audience of
the king at Copenhagen. The astronomer explained that what he wanted
was the means to pursue his studies unmolested, whereupon the king
offered him the Island of Hven, in the Sound near Elsinore. There he
would enjoy all the seclusion that he could desire. The king further
promised that he would provide the funds necessary for building a
house and for founding the greatest observatory that had ever yet
been reared for the study of the heavens. After due deliberation and
consultation with his friends, Tycho accepted the king's offer. He
was forthwith granted a pension, and a deed was drawn up formally
assigning the Island of Hven to his use all the days of his life.

The foundation of the famous castle of Uraniborg was laid on 30th
August, 1576. The ceremony was a formal and imposing one, in
accordance with Tycho's ideas of splendour. A party of scientific
friends had assembled, and the time had been chosen so that the
heavenly bodies were auspiciously placed. Libations of costly wines
were poured forth, and the stone was placed with due solemnity. The
picturesque character of this wonderful temple for the study of the
stars may be seen in the figures with which this chapter is
illustrated.

One of the most remarkable instruments that has ever been employed in
studying the heavens was the mural quadrant which Tycho erected in
one of the apartments of Uraniborg. By its means the altitudes of
the celestial bodies could be observed with much greater accuracy
than had been previously attainable. This wonderful contrivance is
represented on the preceding page. It will be observed that the
walls of the room are adorned by pictures with a lavishness of
decoration not usually to be found in scientific establishments.
