Sundial – ca. 1917
Did you know that the sundial is the earliest type of timekeeping device? The oldest known sundial dates to about 1500 BC, an ancient Egyptian “shadow clock” made from green schist, a type of metamorphic rock. This bronze sundial has a unique shape and unusual inscription on the back side; “Count that day lost whose low descending sun views from thy hand no noble action done.”
