Don’t you find beautiful custom-made clocks interesting?  Throughout history, the creation of a beautiful clock has been a skill and art form meticulously studied.  Master instructing apprentice, handing down secrets not to be shared with the competition.  Who could become the most renowned clock maker of their time?  Centuries ago, the creation of a unique work of art in the form of a beautiful clock was not just commissioned as a time measuring device.  These clocks were also seen as symbols of status.  A measure of the wealth or technological advancement of the owners or developers of the clock, in comparison to other clockmakers in other nations.  Which brings me to the Prague Astronomical Clock.
