On the town clock of Compiègne, which was built in 1405, three figures of soldiers, or "jaquemarts," so-called (in England they are called "Jacks"), struck the hour upon three bells under their feet; and they are doing it still. The great clock of Dijon has a man and a woman sitting upon an iron framework which supports the bell upon which they strike the hours. In 1714 the figure of a child was added, to strike the quarters. The most popular of the mechanical figures was the cock, flapping his wings and crowing. The clock on the Aschersleben Rathaus shows, besides the phases of the moon, two pugnacious goats, which butt each other at each stroke of the hour; also the wretched Tantalus, who at each stroke opens his mouth and tries to seize a golden apple which floats down; but in the same moment it is carried away again. On the Rathaus clock in Jena is also a representation of Tantalus, opening his mouth as in Aschersleben; but here the apple is not present, and the convulsive efforts of the figure to open the jaws wide become ludicrous. One of the first clocks with which important astronomical works were connected is that of the Marienkirche in Lübeck, now restored. Below, at the height of a man's head, is the plate which shows the day of the week, month, etc.; these calculations are so reliable that the extra day of leap-year is pushed in automatically every four years. The plate is more than three meters in diameter. Above it is the dial, almost as large. The numbers from 1 to 12 are repeated, so that the hour-hand goes around the dial only once in twenty-four hours. In the wide space between the axis which carries the hand and the band where the hours are marked, the fixed stars and the course of the planets are represented. The heavens are here shown as they appear to an observer in Lübeck. In the old works the movement of the planets was given incorrectly, for they all were shown as completing a revolution around the sun in 360 days. Of course this is absurd. Mercury, for example, revolves once around the sun in eighty-eight days, while Saturn requires twenty-nine years and 166 days for one revolution. When this astronomical clock was repaired, some years ago, a very complicated system of wheels had to be devised to reproduce accurately the great difference in the movement of the planets. The work consumed two years. There are a great number of moving figures on the Lübeck clock, but they are not of the most conspicuous interest. In spite of this, however, they excite more wonder among the crowds of tourists who are always present when the clock strikes twelve than the really remarkable and admirable astronomical and calendar works.
