Vertical Dial |
Dial 870 |
| This is a rare American stained glass sundial, accurately telling time and season. It occupies the center panel of a five panel window that forms a cross. The vertical sundial panel measures 28x28 inches and declines 48° west of south, so it only functions in the afternoons. The dial is longitude corrected and indicates Daylight Saving Time when readings are adjusted using the Equation of Time. The gnomon is a 3/4 inch brass ball nodus attached by a non-polar axis rod to the aluminum Sussman window frame. It is the only stained glass sundial in the world that uses frosted colored stained glass to enhance the view of the nodus shadow. It has three seasonal date lines, a solar noon mark, and other marks showing special anniversary dates. It contains the traditional fly, seen on the the lower yellow panel between 1pm and 1:30pm. |

| Bronze 36 in. sundial titled "Garden of Eden". Smithsonian notes: "In Garden of Eden Sundial, the long stick would indicate the time by casting a shadow on the numbers that line the inside of the sphere. Marie Louise Speed commissioned this depiction of the Garden of Eden to decorate private grounds surrounding her estate outside Louisville, Kentucky. In the scene, Adam and Eve grasp the fruit of knowledge that will drive them from paradise. Manship patterned Adam’s hair on the serpent’s scales to emphasize man’s fall from grace." |

| With a bit of whimsy at the end of each day for over two years, Dr. James Griffith marked the position of a ray of sunlight on a wall that entered from a west window overlooking the Potomac river. The result is an analemma, tracing the sun's position at 4:10 pm E.S.T. throughout the seasons. Dr. Griffith was a chemist, but as written on a plaque next to the analemma, "Exactly what this has to do with chemistry per se is not perfectly clear, but Viva Principia Scientifica!" |

Dial 204 |
| Horizontal dial about 16 inch square made of bronze. Gnomon is 4.125 inch high, 5 inch long. Below gnomon is motto, "Horas non numero nisi serenas" (I only count sunny hours). House was built in 1805 and is now open to the public as a museum. Years before this property was opened to the public, a family member brought this dial from Crossbasket Castle in Scotland, the family seat. The lengthy inscription is probably a later addition, since it is unlikely that they would be quoting Whittier in Scotland. The gnomon angle is 39? 30', probably made for the Washington DC location. However, the dial plate has a latitude of about 48? N, certainly not Scotland. What is the true origin of this dial? |
