Description:
  • A 51 x 36 foot horizontal dial with a 21 foot welded silicon bronze gnomon standing 14 feet high. The hour lines are copper inlaid in concrete and the hour markers are 4 inch high bronze Arabic numerals. At solar noon, sunlight passing through a slit in the gnomon illuminates the noon marker with a line of sunlight while prisms on the end of the gnomon project rainbows onto this line of light, making the sculpture a seasonal calendar as well as a way to tell time.

    Created by sculptor Robert Perless, Sun Dagger functions as a unique celestial observatory to amplify the synergy of man and nature. It also works as a seasonal calendar, celebrating the winter and summer solstices and the vernal and autumnal equinoxes with rainbows crossing the line of sunlight from the gnomon slit and falling on inscribed plaques.
