that as soon as some people learn that in this book
which I have written concerning the revolutions of the heavenly bodies,
I ascribe certain motions to the earth,
they will cry out at once that I and my theory should be rejected.”
(1473 – 1543)
The astronomical clock of Lund Cathedral, Lund, Sweden, the Horologium mirabile Lundense, was constructed c. 1380. After having been in storage since 1837, it was restored and put back in place in 1923. On top of the clock there are two knights that mark the hours. The upper board of the clock is the astronomical clock. It shows, among other things, the different phases of the Moon and where the Sun sets.
Nicolaus Copernicus (1473 – 1543) was a Renaissance astronomer who formulated a heliocentric model of the Universe which placed the Sun, rather than the Earth, at the center.
