Aquillius found in his province sufficient material for the prolongation of the war. Although the fall of Aristonicus had doubtless brought with it the dissolution of the regular armies of the rebels, yet isolated cities, probably terrorised by revolted slaves who could expect no mercy from the conqueror, still offered a desperate resistance. In his eagerness to end the struggle the Roman commander is said to have shed the last vestiges of international morality, and the reduction of towns by the poisoning of the streams which provided them with water,[536] while it inflicted an indelible stain on Roman honour, was perhaps defended as an inevitable accompaniment of an irregular servile war. The work of organisation had been begun even before that of pacification had been completed. The State had taken Perperna's success seriously enough to send with Aquillius ten commissioners for the regulation of the affairs of the new province,[537] and they seem to have entered on their task from the date of their arrival.[538] There was no reason for delay, since the kingdom of Pergamon had technically become a province with the death of Attalus the Third.[539] The Ephesians indeed even antedated this event, and adopted an era which commenced with the September of the year 134,[540] the reason for this anticipation being the usual Asiatic custom of beginning the civil year with the autumnal equinox. The real point of departure of this new era of Ephesus was either the death of Attalus or the victory of the city over the fleet of Aristonicus. But, though the work of organisation could be entered on at once, its completion was a long and laborious task, and Aquillius himself seems to have spent three years in Asia.[541] The limits of the province, which, like that of Africa, received the name of the continent to which it belonged, required to be defined with reference to future possibilities and the rights of neighbouring kingdoms; the taxation of the country had to be adjusted; and the privileges of the different cities proportioned to their capacity or merits. The law of Aquillius remained in essence the charter of the province of Asia down to imperial times, although subsequent modifications were introduced by Sulla and Pompeius. The new inheritance of the Romans comprised almost all the portion of Asia Minor lying north of the Taurus and west of Bithynia, Galatia and Cappadocia. Even Caria, which had been declared free after the war with Perseus, seems to have again fallen under the sway of the Attalid kings. The monarchy also included the Thracian Chersonese and most of the Aegean islands.[542] But the whole of this territory was not included in the new province of Asia. The Chersonese was annexed to the province of Macedonia,[543] a small district of Caria known as the Peraea and situated opposite the island of Rhodes, became or remained the property of the latter state; in the same neighbourhood the port and town of
