his teachers that though he was an ardent student, yet the things
which interested him were the movements of the heavenly bodies and
not the subtleties of metaphysics.

On the 21st October, 1560, an eclipse of the sun occurred, which was
partially visible at Copenhagen. Tycho, boy though he was, took the
utmost interest in this event. His ardour and astonishment in

what he so greatly wanted to know. In those days books of any kind
were but few and scarce, and scientific books were especially
unattainable. It so happened, however, that a Latin version of
Ptolemy's astronomical works had appeared a few years before the
