We had tickets for a 2:00PM tour. When we finally reached Versailles, it was about 10 minutes before the hour. We tried to get a taxi to take us up to the palace, but he refused. Pat ran ahead (literally, and it was another of the UPHILL runs) to try to catch the tour for us and to see if they would wait for all of us to get there. When she got there, the tour had just left. Another guide ran ahead to stop the tour for us. After we all got there, this lady also brought all of us a drink of water. We must have looked like a ragged bunch!
Louis XIV was well known for his patronage of the arts and that especially included the sciences. There are many scientific examples in the palace at Versailles. This clock not only told the time but also the month, day of the week, and the year. The globe on top also showed the phases of the moon and the astrological signs.
