Great Falls Virginia USA Horizontal Dial 633
A phosphor bronze horizontal dial whose face is 17.7 inches across four rounded cruciform arms. Designed, made and presented by Tony Moss to commemorate the establishment of the first English settlement at Jamestown on May 14, 1607. The most striking feature is the inclusion of reproductions of the King James Great Seal of the English Virginia Company. The "navette" (little boat) shape of the seal is also reflected in a similar shape for the dial itself. These "English" features are balanced by an American input in the form of the "Celebrate Virginia" logo and that of the local Analemma Society that co-funded the pedestal along with Fairfax County Park Authority. A unique rounded-cruciform shape encompasses all the above elements together with the NASS logo and appropriate inscriptions. The dial is calibrated in 3-minute intervals and quarter hours.
