Sundial Hour Lines
The gnomon of a sundial is the object used to cast the time-telling shadow. The Bronze Age sundial used two gnomons. Here, the hour lines for each.

On the flip side of the sundial, inexpert carvings attempt to recreate the sundial on side A. These markings aren't properly placed for time-telling.
