by Eusebius, who tells us that Oenomaus was pro- voked to write it in consequence of having been himself deceived by an oracle. (Euseb. Praep. Evang. v. 18, foil., vi. 7; Socrat. //. E. iv. 13 ; Niceph. X. 36 ; Theodoret. TJierap. vi. p. 86, x. p. 141, a.) Julian also speaks of tragedies by Oeno- maus {Orat vii. p. 210). . An epigrammatic poet, the author of a single distich upon Eros, inscribed on a drinking vessel. There is nothing to determine whether or no he was the same person as the philosopher (Brunck, Anal. vol. ii. p. 402 ; Jacobs, Anth. Graec. vol. iii. p. 110.)
. A tragic poet. [Diogenes, p. 1023.] [P.S.]
OENO'NE (OlvwuT}), a daughter of the river-
god Cebren, and the wife of Paris. (Apollod. iii.
12. § 6 ; Parthen. Erot. 4 ; Strab. xiii. p. 596 ;
comp. Paris.) [L. S.]
OENO'PIDES (OtVorrfSrjs), a distinguished
astronomer and mathematician, a native of Chios.
Plato (Erastae,c. 1) mentions him in conjunction
with Anaxagoras, from which it has been concluded
that he was a contemporary of the latter. It may
have been so, but there is nothing else to confirm
the conjecture. He is spoken of in connection with
Pythagoras and his followers, so that he seems to
have been regarded as a Pythagorean. Oenopides
derived most of his astronomical knowledge from
the priests and astronomers of Egypt, with whom
he lived for some time. Diodorus (i. 98) mentions
in particular that he derived from this source his
knowledge of the obliquity of the ecliptic, the dis-
covery of which he is said to have claimed (in the
treatise de Plac. Phil. ii. 12, ascribed to Plutarch).
Aelian ( F. H.x.7) attributes to Oenopides the
invention of the cycle of fifty-nine years for
bringing the lunar and solar years into accordance,
of which Censorinus (c. 19) makes Philolaus to
have been the originator. The length of the solar
year was fixed by Oenopides at 365 days, and
somewhat less than nine hours. (As Censorinus
expresses it, the fifty-ninth part of twenty-two
days.) Oenopides set up at Olympia a brazen
tablet containing an explanation of his cycle. He
had a notion that the milky-way was the original
path of the sun, from which he had been frightened
into his present path by the spectacle of the banquet
of Thyestes. (Achilles Tatius, Isag. in Aral. c. 24.)
Proclus, in his commentary on Euclid, attributes to
Oenopides the discovery of the twelfth and twenty-
third propositions of the first book of Euclid, and
the quadrature of the meniscus. Oenopides is also
mentioned more than once by Sextus Empiricus.
{Hypot. iii. 4, adv. Math. p. 367.) He had a theory
of his own about the rise of the Nile, which was
this, that in the summer the waters beneath the
earth are eold, in the winter warm ; a fact which
he said was proved by the temperature of deep
wells. So that in the winter the heat shut up in
the earth carries off the greater part of the moisture,
while there are no rains in Egypt. In the summer,
on the contrary, the moisture is no longer carried
off in that way, so that there is enough to fill the
bed of the Nile and cause it to overflow. Diodorus
(i. 41) objects to that theory, that other rivers of
Libya, which correspond in position and direction
to the Nile, are not so affected. (Fabric. Bill.
Graec. vol. i. p. 860 ; Ideler, Handbuch der Oirono-
logie, vol. i. p. 302.) [C. P. M.]
OENO'PION (OiVoTrfwj/), a son of Dionysus
and husband of the nymph Helice, by whom he
became the father of Thalus, Euanthes, Melas,
Salagus, Athamas, and Merope, Aerope or Haero
i^hol ad- Apollon. Rhod. iii. 996 ; Pans. vii. 4. §
6 ; Parthen. Erot. 20). Some writers call Oeno-
pion a son of Rhadamanthys by Ariadne, and a
brother of Staphylus (Plut. Tkes. 20 ) ; and Servius
{ad Aen. i. 539 ; comp. x. 763) also calls him the
father of Orion. From Crete he emigrated with
his sons to Chios, which Rhadamanthys had as-
signed to hira as his habitation (Pans. vii. 4. § 6 ;
Diod. V. 79). While he was king of Chios, he
received a visit from the giant Orion, who for a
Isng time sued for the hand of Merope. Once
Orion being intoxicated violated Merope, in conse-
quence of which Oenopion blinded him and expelled
him from his island. Orion, however, went to
Lemnos, where Hephaestus gave to him Cedalion
as a guide, or according to others stole a boy whom
he carried on his shoulders, and who told him the
roads. Orion was afterwards cured of his blind-
ness, and returned to Chios to take vengeance on
Oenopion. But the latter was not to be found in
Chios, for his friends had concealed him in the
earth, so that Orion, unable to discover him, went
to Crete (Apollod. i. 4. § 3 ; Hygin. Poet. Astr. ii.
34 ; Eratosth. Catast. 32 ; Eustath. ad Horn. p.
1623). The tomb of Oenopion continued to be
shown at Chios even in the days of Pausanias (vii.
5. § 6 ; comp. Orion ; V^olcker, Mythol. des Japet.
C?eAc/i/. p. 112, &c.). [L. S.]
OENO'TROPAE (OtVorpoTrat), that is, the
changers of or into wine, was the name of the three
or four daughters of king Anius in Delos, because
they had received from Dionysus the power of
changing water into wine, and any thing else they
chose into corn and olives (Tzetz, ad Lye. 750).
When Agamemnon heard this, he wanted to carry
them off by force from their father, that they might
provide for the army of the Greeks at Troy ; but
they implored Dionysus for assistance, and were
accordingly metamorphosed into doves. ( Ov. Met.
xiii. 640 ; Serv. ad Aen. iii. 80.) [L. S.]
OENO'TRUS {OXuwrpos), the youngest son
of Lycaon who emigrated with a colony from
Arcadia to Italy, and called the district in which
he settled, after himself, Oenotria (Pans. viii. 3. §
2 ; Virg. Aen. i. 532, iii. 165, vii. 85 ; Strab. vi.
p. 253, &c.). According to Varro, he was a king
of the Sabines, and not a Pelasgian, and his brother
was called Italus (Serv. ad Aen. i. 536). Accord-
ing to Dionysius (i. 11, &c. ii. 1), Oenotrus was
accompanied by his brother Peucetius, and landed
in the bay of Ausonia. [L. S.]
OEOBA'ZUS (Oto'gafos). 1. A Persian, who,
when Dareius Hystaspis was on the point of march-
ing from Susa on his Scythian expedition, besought
him to leave behind with him one of his three sons,
all of whom were serving in the army. Dareius
answered that, as Oeobazus was a friend, and had
preferred so moderate a request, he would leave him
all three. He then ordered them all to be put to
death. (Her. iv. 84 ; comp. vii. 38, 39 ; Senec. de
Ira., iii. 16, 17.)
. Father of Siromitres, who led the Paricanians in the Greek expedition of Xerxes. (Her. vii. 68.)
. A noble Persian, who, when the Greek fleet arrived in the Hellespont after the battle of Mycale (b. c. 479), fled from Cardia to Sestus, as the place of all most strongly fortified. Sestus was besieged by the Athenians under Xanthippus, and, on the famine becoming unendurable, Oeobazus, with
