lasted till 1315, when reconciliation was effected by the patriarch Niphon (see Gibbon, _Decline and Fall of the Roman Empire_, ed. J.B. Bury, 1898, vol. vi. 467 foll.). Arsenius is said to have prepared from the decisions of the councils and the works of the Fathers a summary of divine laws under the title _Synopsis Canonum_. This was published (Greek original and Latin version) by G. Voel and H. Justel in _Bibliotheca Jur. Canon. Vet._ (Paris, 1661), 749 foll. Some hold that the _Synopsis_ was the work of another Arsenius, a monk of Athos (see L. Petit in Vacant's _Dict. theol. cathol._ i. col. 1994); the ascription depends on whether the patriarch Arsenius did or did not sojourn at Mount Athos. See Georgius Pachymeres ii. 15, iii. _passim_, iv. 1-16; Nicephorus Gregoras iii. 1, iv. 1; for the will of Arsenius see Cotelerius, _Monumenta_, ii. 168. ARSES, Persian king, youngest son of Artaxerxes III., was raised to the throne in 338 B.C. by Bagoas (q.v.), who had murdered his father and all his brothers. But when the young king tried to make himself independent, Bagoas killed him too, with all his children, in the third year of his reign (336) (Diod. 17.5; Strabo 15. 736; Trogus, Prol. x., Alexander's despatch to Darius III.; Arrian ii. 14. 5, and the chronographers). In Plutarch, _De fort. Alex._ ii. 3. 5, he is called _Oarses_; in Johannes Antioch. p. 38, _Arsamos_; in the canon of Ptolemy, _Aroges_ (by Elias of Nisibis, _Piruz_); in a chronological tablet from Babylon (Brit. Mus. Sp. ii. 71, _Zeitschrift fur Assyriologie_, viii. 176, x. 64) he is abbreviated into _Ar_. See PERSIA: _Ancient History_. (Ed. M.) ARSINOE, the name of four Egyptian princesses of the Ptolemaic dynasty. The name was introduced into the Ptolemaic dynasty by the mother of Ptolemy I. This Arsinoe was originally a mistress of Philip II. of Macedon, who presented her to a Macedonian soldier Loqus shortly before Ptolemy was born. It was, therefore, assumed by the Macedonians that the Ptolemaic house was really descended from Philip (see PTOLEMIES).
