HISTORY
            
          For many years it was thought that the astronomical clock was built by the master Hanuš in around the year 1490, but origins of the Prague astronomical clock are older still.
HISTORY OF THE ASTRONOMICAL CLOCK
 
			During the 600 years  of its existence the astronomical clock has lived through a dramatic history.  It has also stood idle for many of those years. In fact at one point it was  intended to be disassembled and scrapped. However, someone always appeared who  repaired and saved the clock. 
			  
			  The idea of  establishing an astronomical clock in Prague originated during the reign of  king Charles IV, who permitted the master horologist Martin entry to Prague. At  that time one astronomical clock was already in existence in the Italian city  of Padova, dating from 1344. 
Charles IV did not live  to see the astronomical clock in Prague. The citizens of Prague first saw the  clock under the reign of his son Václav IV, in the year 1410. The clock was  constructed by Mikuláš of Kadaň, and the calculations were performed by the  royal astronomer and rector of the Prague university, the master Jan  Šindel.  
Mistr Hanuš merely  repaired the astronomical clock in 1490 and perfected into the form which we  know today.  
The astronomical  clock underwent a comprehensive reconstruction in 1945-48 after the clock had  been severely damaged at the end of World War II. All of the figures of the  apostles were replaced at this time. The last repair was conducted in 2005,  during which the machinery of the clock was disassembled, some gear assemblies  were repaired or replaced and was then reassembled.
