(Hist, of Greece, ch. xxix, sect. 5), as referring to the time when Dionysius obtained the virtual sovereignty under that title, in the spring of b. c. 405. It is more probable that it relates to the appointment of the ten generals in the preceding year, and that Hipparinus, as well as Dionysius, was one of these. [dionysius, p. 1033, a.] We hear no more of him from this time, but from the tyrant having married his daughter Aristomache,. as well as from; the position assumed by his son Broii, ft ik clear that he must have continued to hold a high place in the favour of Dionysius as long as he lived.
2. A son of Dion, and grandson of the preceding, who fell into the power of the younger Dionysius, together with the wife and sister of Dion, when the latter quitted Sicily. He was still in the hands of the tyrant when he was shut up and besieged by Dion in the island citadel (b. c. 356), a circumstance of which Dionysius took advantage to endeavour to open secret negotiations with his adversary, but without effect. (Plut. Dion, 31.) While in the power of the tyrant, Hipparinus had been purposely accustomed by him to dissolute and luxurious habits ; of which Dion, as soon as he had become completely master of Syracuse, endeavoured to cure him by restraint and severity, but the boy, unable to endure the sudden change, threw himself from the roof of a house, and was killed on the. spot. (Plut. Dion, 55 ; Corn. Nep. Dion, 4, 6 ; Ael. V. H. in. 4.) According to Timaeus (ap. Plut. 1. c.), his name was Aretaeus.
3. A son oiL the elder Dionysius by Aristo- mache, daughter of No. 1, who succeeded Callippus in the government^or tyranny of Syracuse, b, c. 352. According to Diodorus, he attacked the city with a fleet and army, and having defeated Cal- lippus,. compelled him to fly from Syracuse, of which he immediately took possession (Diod. xvi. 36). The account given by Polyaenus is somewhat different: according to his version, Hipparinus was at Leontini (at this time the head-quarters of the disaffected and exiled Syracusaiis), when he learnt that Callippus had quitted Syracuse with the great body of his forces on an expedition elsewhere, and contrived to surprise the gates and make himself master of the city before his return. (Polyaen. v. 4.) This statement is also in part confirmed by Plutarch (Dion, 58), who relates that Callippus lost Syracuse while attempting to make himself master of Catana, though he does not mention Hip parinus. . He held the supreme power for only two years, during which he appears to have excited the contempt of his subjects by his drunkenness, as well as their hatred by his tyranny, and he fell a victim to assassination. (Diod. xvi. 36 ; Theo- pompus, ap. Atlien. x. p. 436, a.; Ael. V. H. ii. 41.) [E. H.B.]
HIPPASIUS ('Iirirdffios), a veterinary sur geon, who may perhaps have lived in the fourth or fifth century after Christ. He wrote some works, of which only a few fragments remain, which are to be found in the collection of writers on vete rinary surgery, first published in a Latin version by Joannes Ruellius, Paris, 1530, fol., and after wards in the original Greek, by Simon Grynaeus, Basel, 1537, 4to.- [W. A. G.] . HI'PPASUS ("Immffos). • • I. The father of Actos the Argonaut. (Apollod. i. 9. § 16; Hygin. Fab.U.)
2. A son of Ceyx, king of Trachis, and the com-
5. A son of Eurytus, was one of the Calydonian hunters. (Hygin. Fob. 173; Ov. Met. viii. 313.)
6. A son of Priam. (Hyg. Fab. 90.) [L. S.]
HIPPASUS f EmrcKTor), a Lacedaemonian who is mentioned by Diogenes Laertius (viii. 84) as the author of a work on the Lacedaemonian republic in five books, from'which a statement is quoted by Athenaeus (i. p. 14). The time at which he lived is unknown. [L. S.]
HIPPASUS ("Imrcuros), of Metapontum or Croton (lamblich. Vit. Pytli, c. 18. $$ 81, 88. c.23. § 104), is mentioned both by lamblichus and by Diogenes Laertius (viii. 84) among the elder Py thagoreans. Hippasus is said to have been the founder of a school or sect of the Pythagoreans, called the Acusmatici (aKovcrfAariKoi), in opposition to the Mathematici. Aristotle (MetapJi. i. 3) speaks of Hippasus as holding the element of fire to be the cause of all things: and Sextus Empiricus (ad Pkys. i. 361) contrasts him with the Pythagoreans in this respect, that he believed the dpxrf to be ma terial, whereas they thought it was incorporeal, namely, number. A single sentence quoted by Diogenes Laertius as expressing one of his doctrines seems to mean that he held all things to be in motion and change, but according to a fixed law. (lamblich.Ibid. §§ 81, 88; Villoison, Anecd. Graec. ii. p. 216.) In consequence of his making known the sphere, consisting of twelve pentagons, which was regarded by the Pythagoreans as a secret, he is said to have perished in the sea as an impious man. According to one statement, Hippasus left no writings (Diog. Laert. viii. 84), according to another he was the author of the fjLvffriKos \6yos, written to calumniate Pythagoras. (Id. viii. 7 ; comp. Brandis, Gescli. d. Griech. Rom.PMosoph. vol. i. p. 509, &c.) [C. E. P.]
HIPPIA and HI'PPIUS ('Imrla and "lira-toy, orc/jttttcios), in Latin Equester and Equestris, occur as surnames of several divinities, as of Hera (Paus. v. 15. § 4); of Athena at Athens, Tegea and Olympia (i. 30. § 4, 31. § 3, v. 15. § 4, viii. 47. § 1); of Poseidon (vi. 20. § 8, i. 30. § 4; Liv. i. 9); of Ares (Paus. v. 15. § 4); and at Rome also of Fortuna and Venus. (Liv. xl. 40, xlii. 3 ; Serv. ad Aen. i. 724.) . [L. S.]
HIPPIAS ('I-mr/as), captain of a company of Arcadian mercenaries in the service of Pissuthnes, is named by Thucydides in the story of the fifth year of the Peloponnesian War, b. c. 427. A faction of the Colophonians of Notium dependent on Persian aid introduced him into a fortified quarter of the town ; and here, after the surrender of Mytilene, he was found and besieged by Paches, whose succour was demanded by the exiles of the other party. Paches, under a promise of a safe return into the fortification if no terms should be agreed on, drew Hippias out to a conference; retained him, while, by a sudden attack, the place was carried ; and satisfied the letter of his promise by bringing him back into the fortress, and there shooting him to death.
