| Description: |
- A horizontal sundial 45 x 61 inches with a monofilar brass cable gnomon and tension counterweight. This is the largest horizontal sundial in the US carved on a single piece of stone, taking two years to build. The dial has hour lines from 5am to 8pm, corrected for longitude. Each hour line has an analemma and in the lower right of the dial is a graph of the Equation of Time. A nodus on the wire gnomon indicates date, with declension lines for summer and winter solstice, equinox, and date lines. Time and direction of sunrise and sunset are marked on the equinox and solstice lines. At the base of the gnomon is a 16-point compass rose. On the left side of the dial is a table for telling time by moon shadows. In the center is a copy of the hands from "The Creation" by Michelangelo.
