Sunderland Maryland USA Horizontal Dial 259
A brass horizontal dial 11.5 inches in diameter with a 7 inch high gnomon. The dial is intricately engraved and includes compass points and gradations of the clock to two minutes. Made by "E. Nairne", a London dial maker in the 1750's to 1800. Rector Stephanie Chase Wilson says "I believe it was made specifically for our church as it has the name "All St.s Parish Calvt County" written on the face on the opposite side from "E. Nairne." The oral history of its origins is that it was commissioned by the Rev. Thomas Claggett, rector of All Saints from 1769-1777, and again from 1786-1792. He gave the sundial to the church in thanksgiving for being called as the first Bishop consecrated on American soil on September 17, 1792 in Trinity Church, New York." "About 15-20 years ago the sundial was stolen from the church, but a quick-thinking parishioner got word out to every antique store within 100 miles and several days later it was recovered. A replica was created and now sits outside the church on a pedestal. The original is under lock and key. The only special care it gets is an occasional dusting. "
 
 
Bethesda Maryland USA Horizontal Dial 258
A simple but elegant horizontal bronze dial approximately 18 inches in diameter. Design is a standard design used at U.S. Naval Hospitals. This dial was built specifically for Bethesda Naval Medical Center. Has plain raised hour lines and half-hour lines with Arabic numerals. The dial tells time from 6 AM to 6 PM. The dial base is octagonal stone that tapers into a graceful pillar. The dial sits in a shallow stone bowl about 3 feet from the ground.
 
 
Washington District of Columbia USA Armillary Dial 257
The bronze armillary sphere dial is unremarkable yet is oriented accurately and is complete. About 2 feet in diameter. Hour numerals are Roman and show 5 AM to 7PM. It commemorates a longtime gallery official.
 
 
Washington District of Columbia USA Horizontal Dial 256
Octagonal bronze horizontal dial, mounted just above the ground level. Designed by Richard Schmidt of the USNO staff and cast by Alex Bigler of Equestrian Forge celebrates the 100th anniversary of the move of the USNO to its present site at Observatory Circle. The USNO was founded in 1830. Public, but by appointment only (202-762-1438).
 
 
Leesburg Virginia USA Horizontal Dial 255
A small bronze horizontal dial on an 18 x 18 inch block of marble. Pedestal of Tennessee marble rests on the back of a carved tortoise. The sides of the square block capital are deeply carved with oak leaves and acorns. When the dial was seen in 1998, the dial was not aligned to north. Inspection of the dial face shows that it is not designed for the site latitude of 39? but higher in latitude, perhaps even 44?. It is thought the dial might have been purchased by Edith Eustis, wife of William Cocoran Eustis who owned the Oatlands estate for the first part of the 20th century. The maker's signature, "fecit," and a crown is spurious, since any legitimate dial maker would use name or initials. The date of 1717 is not convincing as it does not match the design of the dial. And, if purchased by Mrs. Eustis, it is probably not French or Italian, since the compass rose is delineated by the English letters for north, south, east and west.
 
 
Alexandria Virginia USA Horizontal Dial 254
A bronze horizontal dial on a hexagonal pedestal. Gnomon angle measures 31.9°, wrong for local latitude. Gnomon is aligned southwest rather than true north. Dial sits in a former fountain installed in 1896.
 
 
Alexandria Virginia USA Vertical Dial 253

New York New York USA Hemicyclium 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 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 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 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 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 245
3 x 4 feet bronze vertical declining S 28° W, 30 feet above the street level.
 
 
Houston Texas USA Armillary 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 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 Equatorial 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.
