Description:
  • This horizontal dial is 16 inches square, made of limestone with a brass gnomon. The gnomon angle is 30 deg, certainly not correct for the dial's latitude of 41 deg. Nonetheless, it appears that the dial was made for its site as the gnomon and dial numbers are rotated on the square to point due north. Arabic numerals mark time by hours from 8 am to 6 pm, with raised hour lines extending toward the gnomon. The equation of time is shown as a graph on one side of the plinth. The limestone is deteriorating with age and is now covered with lichen. The 3 and 4 pm numbers are nearly obliterated and in several more years many of the other hour numbers will vanish. The dial is situated under trees with little opportunity to see the sun.
