Greenville Delaware USA Equatorial Dial 530
A 15-inch cast aluminum equatorial sundial designed and built by Richard Schmoyer originally installed in 1972 and replaced in 1985 after theft. A three-dimensional analemmic gnomon corrects for Equation of Time. The observatory is open to the public every weekday morning.
Rehoboth Beach Delaware USA Horizontal Dial 321
A bronze horizontal dial about 18 inches in diameter. The sundial was designed by Col. W.S. Corkran in 1930 and placed in the Homestead House garden, a 3 1/2 acre site maintained by the Rehoboth Art League since 1938. Col. Corkran died in 1962. The sundial was restored in 1999, set atop a capstan from an old sailing ship. Since 1999 the salt air has continued to deteriorate the plaques and gnomon. The dial face is still quite readable, with Arabic hours from 6am to 6pm delineated in 5 minute intervals. Symbols of the zodiac decorate the dial in a circular arc.
Wilmington Delaware USA Vertical Dial 320
A round limestone vertical dial about 3 feet in diameter with bronze gnomon. Hours are bronze Roman numerals. No hour lines drawn. The dial is set on the side of a beautiful stone tower. According to a plaque at the tower's base, in 1895 Theodore Leissen recommended a large pavilion and observatory be built on the city's highest hill. At the same time the Water Commission needed a water tower. The plans were merged, resulting in a combine stone water tower 115 feet tall holding half a million gallons and a roofed observatory platform. The dial is on the side of this Rockford Tower.
Wilmington Delaware USA Vertical Dial 609
An 18 x 24 inch cast bronze vertical dial offset from supporting wall by 6.25° to align south. Dial face has hour lines with Arabic numerals and depicts a leaf motif with sun and sun rays and two birds.
Winterthur Delaware USA Armillary Dial 806
The 59" armillary is located in the Sundial Garden, designed by Landscape Designer Marian Coffin for Henry Francis DuPont for the family's former tennis court in 1955. It features an antique armillary sundial weighing 70 pounds. It was collected by the DuPont family between 1850-1920.
Winterthur Delaware USA Horizontal Dial 807
A bronze horizontal sundial about 18 inches in diameter. The Arabic hour numbers range from 4am to 8pm, with time delineated into half, quarter, and eighth hours. A side photo of the gnomon shows it is set for about 53° and the top-down photo of the dial (corrected for perspective) confirms this. A DuPont purchase in England?
