Dictionary of Greek and Roman Geography/A'celum
A'CELUM (Asolo), a town of the interior of Venetia, situated near the foot of the Alps, about 18 miles NW. of Treviso. (Plin. iii. 19. s. 23; Ptol. iii. 1. § 30.) The name is written "Axcfioy in our editions of Ptolemy, but the correctness of the form Acelum given by Pliny is confirmed by that of the modern town. We learn from Paulus Diaconus (iii. 25, where it is corruptly written Acilium), that it was a bishop's see in the 6th century.
