The oblique front forms an angle of 33° with the rear vertical plane, very different from the latitude of Nepi, which is about 42°. The noon hour line is almost completely missing. The hour lines from VII to XI and parts of the winter solstice and equinox curves are present. The remaining segments of the day curves are of equal length: 22 mm on the winter solstice curve, 35 mm on the equinox, and 64 mm on the circular intersection with the oblique front cut.  Because of the few elements available it is difficult to make any reliable calculations or any evaluation of how accurate this sundial may have been.",
