The Romans divided their day into twelve hours; the first beginning with the dawn; consequently, at the time of the equinoxes, their hours nearly corresponded with ours. According to Pliny, H. N., ii., 76, Anaximenes was the inventor of the sun-dial; whereas Diog. Laertius (II., i., 3) and Vitruvius attribute the discovery to Anaximander. They were, however, known in much earlier times in the East. Cf. 2 Kings, xx. Sun-dials were introduced at Rome in the time of the second Punic war; the use of Clepsydræ, "water-clocks," by Scipio Nasica.
