Digital Dial |
Dial 1097 |
This is one of John Garret Thew's mass produced "digital sundials" patented on April 5, 1960. The dial casts a numeral onto the dial's central plate that accommodates beams of sunlight and shadow from winter to summer solstice. The numerals (corrected for the hour angle distortion) slowly move across the dial's plate and the hour is read at the meridian line. Perhaps a good selection for advanced technology at MIT to grace their garden, but it has been neglected in recent years. However, Thew was not the first to come up with this digital sundial. In June 1758 Monsieur De Lalande of the Royal Academy of Sciences in a letter to the editors of the Journal des Scavans described a dial by J.L. Bizot (1702-1781) in which, on an internal wall, an angel's hand is raised to point upward at numerals of light cast "by a half-ring of iron...which has small openings every 15 degrees in the form of a numeral..." |

Noon Mark or Meridian Dial |
Dial 1096 |
Dial is a calendar dial that marks noon on the solstices and equinoxes by projecting a circle of sunlight onto one of three horizontal discs on the meridian line dial face. To create the round sunlight spots the vertical arm has three elliptical holes to match the solar angles for the two solstices and the equinox. The disk closest to the gnomon (with highest solar angle) is for the summer solstice. Middle disk is for the equinoxes, and the farthest disk (with lowest solar angle) is for the winter solstice. Notice in the photo that the summer hole in the vertical arm is considerably stretched to account for the high angle of the sun. |

Polar Dial |
Dial 1095 |
It is a polar dial using a rod gnomon. Using a template from Shadows software, the dial is made of handmade ceramic tiles mounted on an aluminum bar frame anchored to a concrete base. Brass borders define winter and summer solstice declination lines, and an aluminum bar defines the E-W equinox declination. Copper analemmas define the sun’s annual path at 7:30/8:30 PST/PDT and hourly until 5/6PM. Metal balls along the analemmas are placed the 1st of each month. Black declination lines mark the ancient Babylonian Zodiacal signs, designated by different colors. Hours are numbered for PST and PDT. Standard time on the hour, accurate to 1 minute, is read on the tile surface when the gnomon shadow is just under the analemma for that hour. The 1st of each month is marked on tiles in early AM and late PM hours, guiding which side of the analemma is used. |

Horizontal Dial |
Dial 1094 |
A simple horizontal dial marked with solar hours, unusual in having a reflective chrome coating of the entire dial (in some spots the chrome has flaked off where the underlying material has started to rust). The gnomon is a triangular vane with a pattern of round holes pierced though it. The dial face is approximately 20" (50cm) square and wraps down at the edges to make a 3" (7.5cm) high block. It stands on a square concrete column about 3' (1m) high, which also contains a hidden Time Capsule. |

Sun Alignment |
Dial 1090 |
"Sky Gate" is a huge 24 foot (7.3m) undulating sculpture of black metal is known as one of Honolulu's most distinctive pieces of public art. There is a hidden astronomical alignment. On zenith days (~28 May and ~18 July) when the sun is directly overhead at the zenith at the moment of local solar noon, the shadow of the sculpture forms a perfect, large circle on the ground directly below. The zenith day noon is known as "Lāhainā Noon", a term coined by the Bishop Museum, and in Hawaiian means "Cruel Sun". Noguchi, the sculptor, didn't leave a plaque, but Tory Laitila, registrar at the Mayor’s Office of Culture and the Arts, says, "Art is a subjective experience, and artists like to leave things for the viewer to discover." Now the Lāhainā Noon is well known and there is usually a crowd with cameras to document this twice annual event. |

Horizontal Dial |
Dial 1076 |
Farenholt sundial for U.S. Naval Hospital Mare Island. Cast bronze, 18 inch (46 cm) diameter circular face, mounted on a cement pedestal 40 inches tall. Only three Farenholt sundials are known to have Spanish mottos: Mare Island is one of them. (Sunnyvale, CA and Hawthorne, NV are the others). We notice other difference from the classic Farenholt sundial: (1) there is no true chapter ring for the hour marks. They are at the end of long hour lines that extend from 4am to 8pm. All other dials are from 6am to 6pm. (2) The hours are delineated in quarter hours. All other dials are delineated in half hours. (3) The gnomon foot is considerably below center (and appears restored) with a raised style edge that is more “art deco” than the curves of other Farenholt gnomons. (4) The naval command is not spelled out. Rather, just the initials “U.S.N.H.M.I”. All other Farenholt dials spell the naval command in full. (5) The date is placed above the command initials. All other dials have the date below the naval command title. (6) There are no Farenholt initials on the dial’s southern edge. All of this may indicate the haste with which the dial was made, perhaps to memorialize those that died in Vallejo due to the 1918-1919 influenza epidemic. |

Sculpture/Artwork |
Dial 1073 |
The sundial is at the base of a larger sculpture, "Fantastical Historical Nautical Instrument" which includes many references to maritime history, navigation, and time keeping. The cast bronze dial plate is 7 inches (18 cm) in diameter, given a dark patina. The dial has what appears to be correctly delineated to tell local solar time. Roman numerals show between the hour marks and time is marked at 5-minute intervals. At center is a compass rose with 16 points of labelled directions. At the south end of the dial is a graphical equation of time. The gnomon is only partially correct with the majority distorted into an upright support for the fantastical nautical instruments and telescope representations above it. A portion of the gnomon may tell time during the hours around noon, but then the dial is overwhelmed by shadows not of its own. Treat this as part of a sculpture and enjoy the art. |

A self-proclaimed "World's Largest Figurative Sundial" centers on a 12 foot (3.6m), 3000 pound (1360 kg) statue of Neptune. His trident, set at an angle of 32 degrees, serves as the gnomon. This massive structure sits on a low dais 26 feet (8m) in diameter, surrounded by low octagonal steps. Neptune is an impressive sculpture by Wayne Edwards. But the hour lines are a disaster. "Edwards enlisted the help of experts Frank Yerkes and Richard Hamilton of the engineering firm Sea Island Engineering, now known as Sea Island Land Survey, LLC" They could find north (and there is an "N" in the chapter ring indicating true north, but regardless of the story about sighting Polaris, the noon mark is aligned -8 degrees to the west, pointing to magnetic north). More serious is the marking of hour lines from IV (am) to VIII (pm). The VI hour lines are opposite, but drawn to the center of the dais that is easily 9 feet (3m) from the base of the trident gnomon where they belong. This great structure will never tell solar time. |

This brass horizontal sundial was donated to the school in or around 1908 by the Visitation School class of 1908. It was moved from St. Paul MN to Mendota Heights, MN in 1966 when the school was relocated. In the spring of 2018 it was moved to a protected garden, but sits on the original 1908 pedestal 3 foot (1m) tall and 18 inches (46cm) square. The original dedication engraved into the pedestal is still plainly visible. The dial itself is approximately 12 inches ( 30 cm) in diameter with raised hour lines on the circumference and raised Roman numeral hour marks on the interior from 6am to 6pm. The dial is in excellent condition, but in 2017 a new brass gnomon was cast as a replacement for the missing simple triangular gnomon. The new 1 inch (2.5 cm) wide gnomon is in the shape of a crescent moon. Although aligned with the noon line, this gnomon will never cast a shadow. telling correct time. It is sad that this 114 year old sundial has been reduced to nothing more than an artistic sculpture. |

The dial presents Tennessee's identity and is dedicated to the school children of Tennessee. 4 copper columns support the dial, honoring the Greek and Roman tradition of placing a sundial in the center of a garden. The capital and base are cast bronze and the foundation is Tennessee crab orchard limestone. Surrounding the base are 5 tomato plants, the State fruit. 3 are enameled red to represent the three stars in the State flag. Sitting on the base is the eastern box turtle, State reptile. Branches from a tulip poplar, the State tree, extend from the north end of the gnomon and a mockingbird, the State bird, sits in the branches. The branches are made of forged bronze and the leaves are copper, cut by hand, then repousséd or shaped by hammering on the reverse side, then enameled. The mockingbird is made of raised and repousséd copper with enamel for color. The legs are bronze for strength. |

The hour markers are Roman numerals in granite stone blocks. The hour lines were laid out using a scale model mounted on a heliodon and set for the summer solstice. The leading shadow of the vertical sculture marks the time. The planes landing at Nashville airport serve as the backdrop to the dial. When the sun is due East-West, the wings form a diamond, allowing shadows to fall through the markers onto the inlaid concrete disk. |

Analemmatic Dial |
Dial 1054 |
An elliptical analemmatic sundial done in a circular motif representing the sun. Dial is in colored concrete and the Zodiac walkway is a series of circles with the month's number. The time is properly marked on the ellipse with a circular marker, but the hour number is at the end of the sun's "flames" on the circumference of a large circle containing the rest of the dial |

Polyhedral Dial |
Dial 1051 |
The dial is overgrown with lichen and stained with dirt. Underneath this rather shabby exterior is a fine polyhedral sundial with ten hemispherical dials arranged in a dodecahedron. Each dial is 8 inches in diameter fitted with a quarter-inch thick bronze gnomon. The gnomons are set in a common direction for the North Celestial Pole of approximately 51 deg latitude. The design and latitude leading to the the conclusion it is a copy of an 18th century English sundial. The dial is similar to NASS #27 in Hartford, CT. which was originally located at The Abbey, Storrington, Sussex south of London. The Nashville dial sits on an ornate flower-motif pillar approximately 8 feet high. Sitting on top of the dial is a shield and rampart lion, similar to the Hartford-Storrington Abbey sundial. |

Horizontal Dial |
Dial 1050 |
Sitting on a low dais is a beautiful red granite sundial. The gnomon is about 1.5m high and 20cm wide sitting in the center of a dial about 2.5m in diameter. Hour lines radiate from the gnomon foot to the edge of the dais, marking the hours from VI (AM) to VI (PM) local solar time. Inscriptions are on both the east and west side of the gnomon, a plaque and names of those who died serving the citizens of the State of Arizona. |

Armillary Sphere |
Dial 1049 |
When is a sundial not a sundial? At first glance it appears to be an armillary sphere, but upon closer inspection, it is missing both a gnomon rod and an equatorial ring to mark the hours. Then, in another view of the dial we see that the angled ring with spokes actually contains hour numbers and could be the missing equatorial ring. Further, it a rod had been attached perpendicular to the ring, and the ring were tilted to the co-latitude, we'd have a working armillary sundial. The missing gnomon rod may have fastened to the meridian ring. Bottom line: with some care, this sundial can be saved and become a working sundial again. |
