Description:
  • Horizontal dial about 16 inch square made of bronze. Gnomon is 4.125 inch high, 5 inch long. Below gnomon is motto, "Horas non numero nisi serenas" (I only count serene hours). The house was built in 1805 and is now open to the public as a museum. Years before this property was opened to the public, a family member brought this dial from Crossbasket Castle in Scotland, the family sea, to Georgetown. The gnomon angle is 39°N 30',.probably made for the Washington DC location. However, the dial plate has a latitude of about 48° N, certainly not Scotland. What is the true origin of this dial? Perhaps Augsburg, Germany?

    To further complicate things, the existing dial face contains a poem by John Greenleaf Whittier (b. 1807 d.1892) around the perimeter, setting the date of the dial in the middle of the 1800's. Whittier was a Northern abolitionist, politician, writer, and poet. How the dial face ended up engraved at 48° N with his poem is truly a mystery.
