Vertical Dial |
Dial 857 |
| The vertical dial is a metal frame approximately 4 x 5 feet set high on a brick wall. Within the frame are metal hour lines from 6am to 5pm marked by Roman numerals. The hour lines are adjusted for the dial's longitude to show time for the 75th meridian. Metal lines for the solstices and equinox are set for the shadow of a small spherical nodus on the gnomon rod. The gnomon itself is anchored to a bronze plate stylized as the Sun. |

Dial 858 |
| The 3 x 4 foot vertical dial is set high in the ashlar sandstone wall of Wilson Hall, the original Physics Building. In the middle of the dial is the Brown University shield, holding the gnomon rod. Surrounding the shield are hour lines. In the original 1890 architect's drawing, the hour marks were Arabic numbers from 6am to 6pm, but as built, the numbers were engraved Roman numerals and set inside the hour lines. Half hour marks were added as well. No longitude offset is made such that the noon hour line is vertical. |

Vertical Dial |
Dial 859 |
| This is a traditional vertical dial approximately 4 x 6 feet. The dial is surrounded by a row of square pink concrete brick. The dial backdrop itself is concrete with decorative dark block squares in each corner. The dial consists of a simple metal frame with hour lines that radiate from a small top central circle, all well proportioned. Hours of 7, 9, 12, 3, and 5 are marked with Arabic numbers, keeping the dial face simple. No solstice or equinox lines, but there is an artistic circular arc surrounding the central circle. Unfortunately the rod gnomon is completely missing. |

Noon Mark or Meridian Dial |
Dial 949 |
| At first glance this is a gleaming stainless steel sculpture 15 feet long by 4 feet high in the shape of a Mobius strip. Although it fits its name "Infinity Possibility", it also contains a meridian noon mark sundial. At the south end of the Mobius, high up on its curved surface is a hole to allow the noontime sun to create a beam of light that hits a lower portion of the Mobius strip. Engraved on the strip is an analemma adjusted for the longitude of Brown University that shows date and civil time throughout the year. The analemma has monthly markers and is delineated with ticks every 5 days. |
