Introduction The Earth


a parable (April 4, 1847)

1. On a high tower in a city of that time, a duke had a magnificent clock erected. Since the tower was octagonal, he had a dial made on each of the eight faces that naturally fell between the eight corners, so that everyone could notice and see the hours from all possible points and see for themselves at what time of day it was, minute and second.

2. In addition to the most precise division of time from the hour to the second, the clock also showed the monthly date, the position of the moon and also the position of the other planets, as well as the daily duration of light from the rising to the setting of the sun, and in addition also the four seasons - but of course, all these special astronomical data on separate astronomical dials attached under the main clock dial.
