CURIOUS CLOCKS
BY CHARLES A. BRASSLER
Many of the German cities of the Middle Ages enjoyed great prosperity, which they liked to exhibit in the form of splendid churches and other public buildings; and each one tried to excel the others. When, therefore, in the year 1352, Strassburg was the first to erect a great cathedral clock, which not only showed the hour to hundreds of observers, but whose strokes proclaimed it far and near, there was a rivalry among the rich cities as to which should set up within its walls the most beautiful specimen of this kind.
The citizens of Nuremberg, who were renowned all over the European world for their skill, were particularly jealous of Strassburg's precedence over them.
In 1356, when the Imperial Council, or Reichstag, held in Nuremberg, issued the Golden Bull, an edict or so-called "imperial constitution" which promised to be of greatest importance to the welfare of the kingdom, a locksmith, whose name is unfortunately not recorded, took this as his idea for the decoration of a clock which was set up in the Frauenkirche in the year 1361. The emperor, Charles IV, was represented, seated upon a throne; at the stroke of twelve, the seven Electors, large moving figures, passed and bowed before him to the sound of trumpets.
This work of art made a great sensation.
Other European cities, naturally, desired to have similar sights, and large public clocks were therefore erected in Breslau in 1368, in Rouen in 1389, in Metz in 1391, in Speyer in 1395, in Augsburg in 1398, in Lübeck in 1405, in Magdeburg in 1425, in Padua in 1430, in Dantzic in 1470, in Prague in 1490, in Venice in 1495, and in Lyons in 1598.
Not all, of course, were as artistic as that of Nuremberg; but no town now contented itself with a simple clockwork to tell the hours. Some had a stroke for the hours, and some had chimes; the one showed single characteristic moving figures, while others were provided with great astronomical works, showing the day of the week, month, and year, the phases of the moon, the course of the planets, and the signs of the zodiac.
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.
