950 DEIMAS.
"2. A Trojan hero, son of Pegasus, was a friend
of Aeneas, and slain by Agamemnon. (Hom. II.
v. 534.) [L. S.]
DEIDAMEIA (A&i't4sa,6e). 1. A daughter of
Bellerophontes and wife of Evander, by whom
she became the mother of Sarpedon. (Diod. v. 79.)
Homer (II. vi. 197) calls her Laodameia.
2. A daughter of Lycomedes in the island of
Scyrus. When Achilles was concealed there in
maiden's attire, Deidameia became by him the
mother of Pyrrhus or Neoptolemus, and, according
to others, of Oneirus also. (Apollod. iii. 13. ~ 7;
Ptolem. Heph. 3.)
3. The wife of Peirithous, who is commonly
called Hippodameia. (Plut. Thes. 30; comp. HIPPODAMEIA.) [L. S.]
DEIDAMEIA (A-isuera). 1. Daughter of
Aeacides, king of Epeirus, and sister of Pyrrhus.
While yet a girl she was betrothed by her father
to Alexander, the son of Roxana, and having accompanied that prince and Olympias into Macedonia, was besieged in Pydna together with them.
(Plut. Pyrrh. 4; Diod. xix. 35; Justin, xiv. 6.)
After the death of Alexander and Roxana, she
was married to Demetrius Poliorcetes, at the time
when the latter was endeavouring to establish his
power in Greece, and thus became a bond of union
between him and Pyrrhus. (Plut. Demetr. 25,
Pyrrh. 4.) When Demetrius proceeded to Asia
to support his father against the confederate kings,
he left Deidameia at Athens; but after his defeat
at Ipsus, the Athenians sent her away to Megara,
though still treating her with regal honours. She
soon after repaired to Cilicia to join Demetrius,
who had just given his daughter Stratonice in
marriage to Seleucus, but had not been there long
when she fell ill and died, B. c. 300. (Plut.
Demetr. 30, 32.) She left one son by Demetrius,
named Alexander, who is said by Plutarch to have
spent his life in Egypt, probably in an honourable
captivity. (Plut Demetr. 53.)
2. Daughter of Pyrrhus II., king of Epeirus,
after the death of her father and the murder of
her uncle Ptolemy, was the last surviving representative of the royal race of the Aeacidae. She
threw herself into Ambracia, but was induced by
the offer of an honourable capitulation to surrender.
The Epeirots, however, determining to secure their
liberty by extirpating the whole royal family, resolved to put her to death; she fled for refuge to
the temple of Artemis, but was murdered in the
sanctuary itself. (Polyaen. viii. 52; Justin, xxviii.
3, by whom she is erroneously called Laudamia;
Paus. iv. 35. ~ 3.) The date of this event cannot
be accurately fixed, but it occurred during the
reign of Demetrius II. in Macedonia (B. c. 239 -229), and probably in the early part of it. Schorn
(Gesch. Griechenl. p. 86) supposes Deidameia to be
a daughter of the elder Pyrrhus, not the younger,
but this is certainly a mistake. [E. H. B.]
DEIMA (AEsiua), the personification of fear.
She was represented in the form of a fearful woman, on the tomb of Medeia's children at Corinth.
(Paus. ii. 3. ~ 6.) [L. S.]
DEIMACHUS (A'iaxosY), four mythical personages. (Apollod. i. 9. ~ 9, 7. ~ 3; Apollon. Rhod.
ii. 955, &c.; Plut. Quaest. Gr. 41.) [L. S.]
DEIMAS (Aeuas), a son of Dardanus and
Chryse, who when his family ahd a part of the
Arcadian population emigrated, remained behind
in Arcadia. (Dion. Hal. i. 61.) [L. S.]

DEINARCHUS.
DEINARCHUS (AdvapXos). 1. The Ias6
and at the same time the least important among
the ten Attic orators, was born at Corinth about
B. c. 361. (Dionys. Deinarch. 4.) His father's
name was Sostratus, or, according to Suidas (s. v.
AEivapxos), Socrates. Though a native of Corinth,
he lived at Athens from his early youth. Public
oratory there reached its height about this time,
and Deinarchus devoted himself to the study of it
with great zeal under the guidance of Theophrastus,
though he also profited much by his intercourse
with Demetrius Phalereus. (Dionys. 1. c. 2; Phlt.
Vit. X Orat. p. 850; Phot. Bibl. p. 496, ed. Bekker; Suidas, I. c.) As he was a foreigner, and
did not possess the Athenian franchise, he was
not allowed to come forward himself as an orator
on the great questions which then divided public
opinion at Athens, and he was therefore obliged
to content himself with writing orations for others.
He appears to have commenced this career in his
twenty-sixth year, about B. c. 336, and as about
that time the great Attic orators died away one
after another, Deinarchus soon acquired considerable reputation and great wealth. He belonged
to the friends of Phocion and the Macedonian
party, and took a very active part in the disputes
as to whether Harpalus, who had openly deserted
the cause of Alexander the Great, should be tolerated at Athens or not. The time of his greatest
activity is from B. c. 317 to B. c. 307, during
which time Demetrius Phalereus conducted the
administration of Athens. But when in a. c. 307
Demetrius Poliorcetes advanced against Athens,
and Demetrius Phalereus was obliged to take to
flight, Deinarchus, who was suspected on account
of his equivocal political conduct, and who was
anxious to save his riches, fled to Chalcis in Euboea. It was not till fifteen years after, B. c. 292,
that, owing to the exertions of his friend Theophrastus, he obtained permission to return to
Athens, where he spent the last years of his life,
and died at an advanced age. The last event of
his life of which we have any record, is a law-suit
which he instituted against his faithless friend,
Proxenus, who had robbed him of his property.
But in what manner the suit ended, is unknown.
The principal source of information respecting the
life of Deinarchus is the treatise of Dionysius of
Halicarnassus, from which is derived the greater
part of what is preserved in Plutarch (Vit. X Orat.
p. 850), Photius (Bibl. p. 496, ed. Bekk), Suidas
(1. c. ), and others.
The number of orations which Deinarchus wrote
is uncertain, for Demetrius of Magnesia (ap. Dionys. 1. c. 1; comp. Suidas and Eudoc. p. 130) ascribed to him one hundred and sixty, while Plutarch and Photius speak only of sixty-four genuine
orations; and Dionysius is of opinion, that among
the eighty-seven which were ascribed to him in
his time, only sixty were genuine productions of
Deinarchus. Of all these orations three only have
come down to us entire, and all three refer to the
question about Harpalus. One is directed against
Philocles, the second against Demosthenes, and
the third against Aristogeiton. It is, however,
not improbable that the speech against Theocrines,
which is usually printed among those of Demosthenes, is likewise a work of Deinarchus. (See
pp. 1333 and 1336 of that oration; Dionys. Hal.
1. c. 10; Liban. A;gium.; H-arpocrat. s.v. dypaciou
and @eoaKpivfrs; Apostol. Proverb. xix. 49.) The
