TLIONEUS. 12. Of Sblvbria. There is (or was) in the Library of St. Mark in Venice, among the Greek MSS., a Commentarius in Arislotelis Scripta Loyica^ by Ignatius, Metropolitan of Selybria, a prelate of unknown date. There is also extant in MS. a work by the same writer, Bios /cat iroKinia rwu dyiwv ^eoffTeiTTwv fieydKwv ^aaihewv koI Iffairo- <tt6ci}v KwvcrravTluov ical 'Eut]s, Vita et Con- versation (SlC, Constcmtini et Helenae. (Fabric. Bihl. Gr. vol. iii. p. 210, vol. vii. p. 46.) 1 3. Of X ANTHOPULi, a monastery apparently at or near Constantinople, was the friend of Callistus II., patriarch of Constantinople, who occupied that see about the close of the 14th or the beginning of the 15th century. Callistus had been a monk of the same monastery, and the two friends were united in the authorship of a work recommending a mo- nastic life, and giving directions for it. The work is cited by their contemporary Symeon, archbishop of Thessalonica, in his Ecclesiasticus Dialogus adversus omnes Haereses. (AUatius, De Si/meonibus, p. 185, ed. Paris, 1664 ; Fabric. Bibl. Gr. vol. vii. p. 46.) There were three Ignatii, respectively described as Chrysopolitanus Abbas, Metropolita Claudiopoli- tanus, and Lophonim Episcopus, among the cor- respondents of Photius, in the ninth century (Photius, Episiolae, ed. Montacutii) ; and an Ignatius Abbas (not -to be confounded with No. 6) among the correspondents of Theodore Studita in the eighth or ninth century. (Theodoras Stu- dita, Epistolae, lib. ii. ep. 24, apud Sirmond, Opera Varia, vol. v.) Several ancient Oriental writers and prelates of the name, Syrians or Armenians, are mentioned by Assemani in his Bibliotheca Ori- entalis. The liturgies composed by some of these are given in a Latin version in Renaudot's Liturg. Orient. (Fabric. £i/i. G^r. vol. vii. p. 47.) [J.C.M.] ILAEIRA ('lAcfetpa), a daughter of Leucippus and Philodice, and a sister of Phoebe, together with whom she is often mentioned by the poets under the name of Leucippidae. Both were carried oif by the Dioscuri, and llaeira became the wife of Castor. (Apollod.iii.lO.§ 3;Schol. arfZj/cqpA. 5 11.) [L.S.] I'LIA. [Rhea Silvia.] ILIO'NA ('lAtwi'a), a daughter of Priam and Hecabe, is not mentioned by the earlier poets and mythographers, but the later ones relate of her the following story. At the beginning of the Trojan war her parents entrusted to her her brother Poly- dorus, for she was married to Polymnestor or Poly- mestor, king of the Thracian Chersonesus. Iliona, with more than sisterly affection, brought up Poly- doras as if he had been her own child, and repre- sented her own son Deipylus as Polydorus. When Troy was taken and destroyed, the Greeks, de- sirous of destroying the whole race of Priam, pro- mised Polymnestor a large sum of money and the hand of Electra, if he would kill Polydorus. Polym- nestor accepted the proposal, but killed his own son Deipylus, whom he mistook for Polydorus. The latter thus escaped ; and after having subsequently learned Polymnestor's crime, he and Iliona put out the eyes of Polymnestor, and then slew him. This legend was used by Pacuvius and Accius as sub- jects for tragedies. (Hygin. Fab. 109, 240; Horat. Sat. ii. ?>, 64; Serv. ad Aen. i. 653 ; Cic. Acad. ii. 27, Tuscul. i. 44.) [L. S.] ILIONEUS {^IKiovevs). 1. A son of Amphion and Niobe, whom Apollo would have liked to save, because he was praying; but the arrow was no ILLUS. 569 longer under the control of the god, (Ov. Met, vi. 261; NiOBE.) 2. A Trojan, son of Phorbas, was killed by Peneleus. (Hom. //. xiv. 489, &c.) 3. One of the companions of Aeneas. (Virg. Aen. i. 120.) 4. A Trojan who was slain by Diomedes. (Q. Smyrn. xviii. 180.) [L. S.] ILISSIADES ('lAto-o-ioSes), a surname of the Muses, who had an altar on the Ilissus in Attica. (Pans. i. 1 9. $ 6.) [L. S.] ILITHYIA. [ElLEITHYIA.] ILLUS, a leading personage in the troubled reign of the Byzantine emperor Zeno, who reigned A. D. 474 — 491. His name is variously written "lAAos (which is the most common fonn), 'lAAos, "lAAous, "lAAos, and 'lAAous, and by Latin writers, Illus, Ellus, and Hyllus. Victor of Tunes in one place calls him Patricius, mistaking his title of Patrician for a proper name. Illus was an Isaurian, but the time and place of his birth are unknown. He is said to have held various offices under the Emperor Leo I. (a. d. 457 — 474), and to have been an intimate friend of Zeno, apparently before his accession. But we first read of him in Zeno's reign and in hostility to that emperor. Basiliscus, brother of the empress dowager Verina, the widow of Leo, had expelled Zeno from Constantinople (a. d. 475) and sent an army in pursuit of him under Illus and his brother Tro- condus (whose name is variously written TpoKovSos, TpoKovvdos, Tpo§ovpdoSn UpoKovpSos, npo/JLov^os, and iSieKovvSos, and by the Latin writers Trocundus and Tricundius) into Isauria, where Zeno had taken refuge. The brothers defeated the fugitive empe- ror (July, a. d. 476) and blockaded him on a hill called by the people near it " Constantinople.'* (Suidas, 8. v. 277^0)1/.) During the blockade Illus and Trocondus, instigated by the senate of Con- stantinople, with whom Basiliscus had fallen into odium and contempt, and themselves discontented with the usurper, were prevailed on by the pro- mises and gifts of Zeno to embrace his side, and to march with united forces towards the capital. At Nice in Bithynia they were met by the troops of Basiliscus under his nephew and general Ar- matus, or Harmatus ('ApixaTos or "Ap^uoros), or Harmatius ; but he, too, was gained over, and Basi- liscus, forsaken by his supporters, was dethroned and put to death (a, d. 477). [Basiliscus.] Illus was sole consul A. d. 478, and in 479 he was instrumental in crushing the dangerous revolt of Marcian, grandson of the Byzantine emperor ot that name [Marcianus], and son of Anthemius, emperor of the West [Anthemius]. Marcian had married Leontia, daughter of the late Emperor Leo by Verina, and sister of Ariadne, Zeno's wife. His revolt took place at Constantinople, where he defeated the troops of Zeno and besieged him in the palace. For a moment Illus wavered, but his failing courage or fidelity was restored by the assurances of an Egyptian soothsayer whom he patronised. Marcian 's forces were cornipted by Illus ; and Marcian himself, with his brothers Procopius and Romulus, was taken. The brothers escaped, but Marcian was sent, either to Tarsus in Cilicia, and made a priest in the church there, or to the foot of Papurius [nairovoios), or Papyrius, a stronghold in Isauria, then used as a state prison. Trocondus, the brother of Illus, was consul A. D. 482 ; and Illus himself enjoyed the dignities of paincius and
