Alexandria Virginia USA Vertical Dial Dial 253

New York New York USA Globe or Hemispheric Dial 250
Granite model of old roman hemicyclium dial with beautiful horizontal bronze gnomon with figure of woman. Hour and date lines may be incorrect. Slightly vandalized and chipped. This dial is a detail of a larger park bench that itself was designed to show time on the equinoxes; refer to Dial 614. The park bench alignment is nominally north but this dial may be misaligned as the Roman hour numbers inscribed on the face run clockwise, incorrect for a south-facing dial. Dial sits atop a large stone park bench.
 
 
New York New York USA Horizontal Dial Dial 249
A 10 inch diameter rough brass horizontal dial, painted brown, on a 3 foot cement pedestal. Gnomon is damaged. Roman hour numerals. Dial sits atop a cast stone pedestal about 3 feet high.
 
 
New York New York USA Armillary Sphere Dial 248
The armillary dial is 30 inches in diameter, built of bronze with a cast stone pedestal. On the outside of equatorial band are golden zodiac signs. Inside the band are roman numerals for hours from 6 am to 6 pm. The dial was vandalized but was refurbished in 2000 and moved a short distance in Parks Dept. renovation. Sal Ton Landscape was the general contractor; Kenneth Lynch & Sons repaired the sundial and made a complete new cast stone fluded base in 2000.
 
 
Queens New York USA Horizontal Dial Dial 247
Paul Manship was commissioned to make the sundial for the 1939 World's Fair in New York. The dial was named "Time and the Fates of Man." Manship wrote, "The Perisphere and Trylon at the World's Fair suggests to me measurements of time and space, so my sundial… relates to the background of the central motif of the Fair." His white plaster sculpture was the biggest sundial in the world, standing 80 feet tall.
 
 
Queens New York USA Vertical Dial Dial 246
A vertical dial on the cupola above the main entrance. Declination 70° 12' 04" E. Painted all white so that no hour lines can be seen.
 
 
New York New York USA Vertical Dial Dial 245
3 x 4 feet bronze vertical declining S 28° W, 30 feet above the street level.
 
 
Houston Texas USA Armillary Sphere Dial 244
A 72 inch painted steel armillary dial with meridian, equatorial, horizon, Arctic and Antarctic rings. Equatorial ring has hourly Roman numerals and zodiacal symbols on its exterior. A bronze plaque on the base explains the armillary operation and provides a table of combined EOT and longitude corrections. Since Houston is more than 5 degrees from the time zone meridian, the longitude correction is almost 22 minutes, greater than the largest EOT correction, resulting in the combined corrections to always add to the dial time. Dial is mounted to a two foot diameter concrete pedestal. This dial was restored in 2000 by the Houston Municipal Art Commission funded by Searcy and Elizabeth Bracewell.
 
 
Baltimore Maryland USA Vertical Dial Dial 243
18 x29 inch vertical dial. Solar noon analemma, equinox and solstice lines, horizontal lines, line showing approx shadow lengths on April 15 and Aug 31. Lines sandblasted into veined white Carrera marble. Dial is calibrated for EDT. AM hours indicated by shadow of stile's western edge, PM, by shadow of its eastern edge. When shadow tip is bisected by appropriate seasonal segment of the line of the analemma, it is 1:06:35 PM.
 
 
Goldendale Washington USA Cylindrical Dial Dial 242
The sundial has a 53-inch semicircular steel equatorial ring and is 18-inches wide. The 18-inch rod gnomon is suspended above the dial by two horizontal rods. A small cross-bar in the middle of the gnomon acts as a nodus for telling the date. A mechanical adjustment allows for the equation of time correction. The dial is mounted on a large boulder on the Northwest end of the Goldendale Observatory close to the Solar Telescope Building.
 
 
Maryhill Washington USA Sun Alignment Dial 241
The Maryhill Stonehenge was the first monument in the US to honor the dead of World War I. It is 180-feet across with pillars of reinforced concrete, duplicating, as nearly as possible the original size and design of Stonehenge. The outer circle has thirty 16-foot pillars while the inner circle has forty pillars 9-foot high. Build by a wealthy entrepreneur Sam Hill as a memorial to servicemen of Klickitat County.
 
 
Penticton British Columbia Canada Analemmatic Dial Dial 240
This analemmatic dial, the "Skaha Solar Timepiece", dates from 1984 and spans an area of 65' x 35'. At the center is a platform marked out with a steel analemma, acting as the date scale. The steel is embossed with a date scale and zodiac. The hour and cardinal direction markers are concrete posts, installed in 1998 to replace the rotted originals. The size and positioning of the analemma is somewhat mismatched to the placement of concrete markers, but overall it is a well-made piece in a pleasant setting. A nearby explanatory plaque claims, incorrectly, that this is the third-ever analemmatic sundial in the world.
