Originally designed for a location such as Chicago, this dial can be adapted to any latitude. The circular member becomes more horizontal nearer the equator, more vertical near the poles. While the model pictured is made of limestone, the actual dial would have to be made of metal or concrete due to the weight of the dial and the torsional weakness of stone. As it appears, this dial is capable of keeping local mean time. With an adjustable dial piece or a properly bent gnomon, this dial is quite capable of keeping clock-accurate daylight savings time. In other words, you could set your watch by it! This dial was designed as an experiment in creating a virtually indestructable dial. The gnomon (the rod that goes from the holder to the top of the dial brace) is tensioned between the two pieces by means of two threaded ends, rendering it virtually unbendable. With concrete construction, the dial would last more than one lifetime. For information about contracting the construction of a dial based on this model in any size from 1-3 meters in height, please contact the artist.
