| Description: |
- The dial plate is a 16 x 16 inch square piece of milk glass, with the hour lines and Arabic numerals made by sandblasting through a photo-etched stencil and then spraying black with lithichrome paint into the etchings. The triangular gnomon is made of 3/8 inch thick stainless steel. Saint Louis sculptor Abraham Mohler made the pedestal from EW Gold limestone quarried near Ste. Genevieve, MO. It is 18 x 18 inches square and 40 inches tall.
Comment on Photo #3: The photo was taken at 3:54 PM CDT on Sept. 15. The solar time shown by the dial is exactly 3 PM. SolarTime = CivilTime - Longitude – EOT used CST = 2:54, Longitude from Time Meridian = 0:0:55, and the Equation of Time = 0:4:30 on Sept. 15, the result is SolarTime = 2:59:25, indicating that the dial displays solar time to good accuracy.
