A´CIUM a small town on the E. coast of Sicily, mentioned only in the Itinerary (Itin. Ant. p 87), which places it on the high road from Catana to Tauromenium, at the distance of 9 M. P. from the former city. It evidently derived its name from the little river Acis, and is probably identical with the modern Act Reale, a considerable town, about a mile from the sea, in the neighbourhood of which, on the road to Catania, are extensive remains of Roman Thermae. (Biscari, Viaggio in Sicilia, p. 22; Ortolani, Diz. Geogr. p. 9.)
