- ANALEMMIC-EQUATORIAL SUNDIALS -

"For in and out, above, about, below,
'Tis nothing but a Magic Shadow-show,
Play'd in a Box whose Candle is the Sun,
Round which we Phantom Figures come and go."
... Fitzgerald: Rubaiyat of Omar Khayyam

First Brass Sundial       Brass 26"w x 14"h x 14"d Prototype Sundial (127k.jpg). My first sundial, which I hand-cut, filed, sanded and shaped from 1/4" brass plate. I hand-struck all of the scales, had the text and numbering machine engraved, then rolled the equatorial scale to the proper curvature and brazed, polished and assembled the final pieces. I remember being quite amazed when I set this finished sundial outside for the very first time, aligned it roughly on the ground with our E-W fence line, and discovered that it actually worked!

Ann Morrison Park Sundial       I placed this Stainless Steel 6'w x 4'h x 4'd Sundial Sculpture (110k.jpg) in Boise's Ann Morrison Park in 1998. Materials and labor for this sundial were donated by JST Manufacturing Inc. I really like this design for its simplicity, and because it visually demonstrates very clearly the apparent motion of the sun "about" the earth throughout the day and the year. It indicates the time to within less than a minute, the date to within the day and it also adjusts for Daylight Saving Time!

Herrett Center Sundial       A newer version of this sundial was installed in 2006 at the Herrett Center for Arts and Science, located on campus at the College of Southern Idaho in Twin Falls. Two similar sundials have gone to private estates in Wyoming and Wisconsin, since.

New Millennium Sundial       The New Millennium Sundial!   Here is the first prototype completed for a 24"w x 17"h x 17"d anodized aluminum sundial, suitable for installation in home yards and gardens. I call this sundial the New Millennium sundial because its analemmic gnomon has been optimized to achieve maximum date and time accuracy later this century, in 2050 AD. It too will indicate the time to within less than a minute, the date to within the day, and adjusts for Daylight Saving Time! I would like to eventually manufacture and market these, but unfortunately, they are not in production or available yet.

Tempus captum!
