Williamsburg Virginia USA Horizontal Dial 363
Bronze horizontal dial 36 inches in diameter. The sundial was constructed in memory of their beloved scoutmaster Sydney "Mike" Mitchell. The $3000 cost was donated from former scouts and friends. The Boy Scout Law is cast around the outer diameter of the sundial. Various Scouting awards that the Scoutmaster received are also cast into the sundial.
Williamsburg Virginia USA Armillary Dial 877
This armillary is constructed of welded carbon steel narrow bands approximately 4-feet in diameter sitting on an iron post about 3-feet high. The equatorial band has no engraved or embossed time marks, but the simple rod gnomon has two side rods. According the the WPL website, "Time on the sundial is read by looking at where the gnomon shadow is cast. This shadow will be the middle, thicker shadow of the three shadow-lines ... Although hours are not marked off on this sundial, you can estimate the time of day by thinking of the gnomon shadow hoop as the clock face and the shadow as the hour hand of that clock." Well, not exactly. The hours are at 15-deg intervals with 12 noon at the bottom of the equatorial band at the intersection of the meridian band. This armillary is more of a sculpture than a timepiece. Yet the armillary has the traditional tropic of Capricorn and Cancer bands as well as Arctic, Antarctic,and horizontal bands.
Williamsburg Virginia USA Horizontal Dial 115
A 14 inch square brass horizontal dial with hour lines and Roman numerals, compass rose and inscriptions honoring John Barrow. A fluted square pillar supports the dial.
Williamsburg Virginia USA Horizontal Dial 116
A unique bronze 12-3/8 inch octagonal horizontal dial with one main hour ring for local time and six subsidiary rings that give the time in London, Vienna, Constantinople, Jerusalem, Barbados and Mexico City. The main hour ring shows hours in Roman numerals and ten minute intervals in Arabic numbers; each hour is divided into sixty minute intervals and "fleur-de-lis" decorations are placed at the thirty-minute marks. The subsidiary rings are inscribed with Roman numerals for daylight hours and Arabic numbers for night hours. The presence of subsidiary rings suggests the dial was made with an instructive or "world-view" intent.
Woodbridge Virginia USA Horizontal Dial 534
A large 62 foot diameter horizontal sundial of grey concrete and brick with a 10 foot high steel gnomon. The dial was designed to memorialize the victims of the 9/11/2001 terrorism and includes four inlaid plaques on which the gnomon shadow falls at 8:45, 9:03, 9:37 and 10:07 AM, the times of the four air crashes. Hour markers are inset brass Roman numerals. The hour lines and NESW compass rose are 2 inch wide inset brass strips.
Woodbridge Virginia USA Horizontal Dial 861
This horizontal dial sits on a low concrete dais 13 feet in diameter. At the interior is an oculus 3 feet in diameter with loose gravel from which a 10-inch I-beam gnomon emerges. The I-Beam extends approximately 4 feet into the air with the north end cut vertical to the ground and then canted back creating a graceful taper on the underside. The dais concrete is of two colors: an inner pink ring 9 feet in diameter and an outer earth-toned ring that serves as a 2 foot wide chapter ring.
