- Description:
- This modern etched glass sundial faces nearly due south (declining only 48' East of South) with hour lines from 6am to 6pm marked in Roman numerals. The dial is a large 5 x 9 feet and held extended from the windows behind. The gnomon is a simple brass rod without nodus. No solstice lines or other embellishments mark the clean look of the dial face, making it easier to read from street level 3 stories below. The dial can also be read from inside the building. Designer Jim Tallman reports that the sundial was an interesting challenge to remotely determine the exact direction of the curtain wall on the building as the sundial was to be mounted three stories above the street. It was necessary to make subtle adjustments to the sundial calculations, layout and gnomon configuration, and installation details so that no shimming would be required and so that the glass dial panel would visually match the strong vertical and horizontal lines of the structural members in the curtain wall behind the dial. At street level is a plaque indicating both longitude correction and the equation of time.
