has become the keeper of the clock and he installed a manufacturing of the tower clock. He was a councillor and it was his initiative that lead towards the so-called big repair and reconstruction, during the years 1864-1866. It was Ludvík Hainz, whose shop was right opposed to the astronomical clock and he was watching the sad status of the clock for years. But all ended up well, when in 1865 a clock-maker was found who could put life back into the difficult mechanism. It definitively stopped in 1824 and nobody could repair it then, so it was decided that it would be destroyed. The astronomical clock stopped in 1787 and according to the councillors, it was supposed to end up in an ironworks, but, still, it was partly repaired. Nothing has been written about the councillors blinding him afterwards. The fact is, that by the end of the 15th century, mistr Hanus (whose name has been identified by the historians as the clock-maker Jan Růže) repaired the astronomical clock – put it into operation again. The famous story of mistr Hanus, who built the Prague astronomical clock and whose eyes were struck out afterwards so that he couldn’t re-create the creation, is not based on truth. It was built in 1410 by Mikulas of Kadan. The old-town square astronomical clock is a part of the South wall of the Old-town city hall in Prague. Technical miracle which has been astonishing the whole world for 600 years. Astronomical clock, a genial machine, which has for centuries shown not only time and date, but also the position of the Sun, phases of the Moon, astronomical cycles and the Christian holidays.
