ACIS, (Ovid, Theocritus); a river of Sicily, running from a very cold spring, in the woody and shady
foot of mount Ætna, eastward into, and not much above a mile from, the sea, along green and pleasant banks, with the speed of an arrow, from which it takes its name. It is now called Acti Iaci, or Chinei, according to the different Sicilian dialects: Antonine calls it Actius. Also the name of a hamlet at the mouth of the Actis.
