The Sundial Tour for the NASS conference in St Louis Missouri visited the
Missouri Botanical Garden where three new sundials were on display. There was a
dedication ceremony for Ron Rinehart's "scientific sundial". See
http://www.scisundials.com/SciSundials/Welcome.html Don Snyder, our local host,
donated a "Schmoyer Sunquest" sundial by Bill Gottesman. See
http://www.precisionsundials.com/schmoyer.htm
The highlight for me was the Ottoman Sundial I designed and Abraham Mohler
carved. The reoriented dial was completed just in time for the Garden Members
meeting and the NASS tour. This dial with a 28' square marble dial plate stands
42' high as a centerpiece in the Ottoman Garden. It has two gnomons and four
time systems: The polar gnomon works with the outer scale to show regular solar
time based on 12 noon. The Ezanic dial with a vertical gnomon shows Babylonian
hours based on 12 sunrise, Italian hours based on 12 sunset and Moslem prayer
times, Zuhr and Asr. The plinth is now aligned with the axis of the garden (N
9ยบ E) and the dials are aligned to the polar axis. The NASS members can
confirm that the dial now accurately shows correct solar times.
I would like to thank NASS members and many on this list who provided
information and advice on this project. It is a beautiful dial that I am
pleased to have the opportunity to provide the design. Abraham Mohler, a local
sculptor in St Louis did an excellent job fabrication the dial and accurately
carving the lines
