As early as 1352 an astronomical clock was begun under bishop Berthold of Bucheck, and finished two years after by an unknown artist, in the time of John of Lichtenberg. It was fixed to the wall facing the present one. The frame-work of that first clock was all of wood; the stones that formed its basis are to this day seen projecting from the wall. It was divided into three parts; the lower part contained a universal calendar; in the middle was an astrolabe, and in the superior division were seen the three wise men and the Virgin Mary carved in wood; the wise men bent every hour before the Virgin, by means of a peculiar mechanism, which at the same time put in motion a chime of harmonious sounds and a cock crowing and flapping his wings. The exact time at which this clock, which in the fourteenth century must have been a wonderful piece of workmanship, and was called the clock of the three sages, ceased going, is not known: it had been stopped for a long time, when in 1547 the magistrate of the town decided on having another made and putting it opposite the old one, in the very place the clock now occupies. Three distinguished mathematicians furnished the plan and superintended the execution of it: they were Dr Michel Herr, Christian Herlin, professor of mathematics at the school of Strasburg, and Nicholas Prugner, who, after preaching the reformation at Mulhouse and at Benfeld, occupied himself at Strasburg with mechanics and astrology. These three learned men began this work, but did not terminate it; it was resumed in the year 1570 by a pupil of Herlin, named Conrad Dasypodius of Strasburg, where he was a professor of mathematics. Dasypodius drew the design of the clock, but its execution was confided to two skilful mechanics of Schaffhouse, the brothers Isaac and Josiah Habrecht; Tobias Stimmer, also of Schaffhouse, had the charge of the paintings. This master-piece of the mechanical art of the sixteenth century was completed in 1574; it ceased going in 1789. As the exterior distribution of the present clock is nearly the same as that of the old clock, we shall abstain from describing the latter. In 1836 the corporation of the town of Strasburg adopted the resolution of causing this curious monument to be repaired. To Mr. Schwilgue, a distinguished mechanician of Strasburg, his native place, this remarkable work was entrusted; he began it the 24th of June 1838 and finished it at the end of 1842.
