| Description: |
- One of Bill Gottesman's unique-design Renaissance dials of cast and structural bronze with a 27 inch diameter helix with a celestial-north aligned axis. Time is told by a focused beam of light that moves around the helix throughout the day. The light beam is reflected from a long cylindrical unsilvered mirror in a structure that supports the helix. A sliding time scale within the helix can be adjusted for EOT and DST and includes longitude correction. Once this scale is adjusted for date, the dial shows civil, or clock, time. The dial base is cast bronze allowing adjustment for latitude and placed on a concrete pedestal with a black granite plinth.

General Information: | Inscription: | - Owner: Universities at Shady Grove
| - On Plaque at sundial base:The Renaissance Sundial is large bronze helical focusing sundial, the only of one of its kind. It projects a sharply focused beam of sunlight onto a helical time scale, telling time with extreme accuracy. The timescale slides in its helical track, allowing adjustment for daylight savings and the equation of time. The width of the beam of light on the helix is 2 minutes of time, the same as the sun in the sky.
To Read the time
1. Locate the beam of light on the inside of the helix
2. Because of the mirror, read the time right to left
