Iliad (Rapsodies 7 to 12)   

Agamemnon? It was Iphidamas son of Antenor, a man both brave and of
great stature, who was brought up in fertile Thrace the mother of
sheep. Cisses, his mother's father, brought him up in his own house
when he was a child- Cisses, father to fair Theano. When he reached
manhood, Cisses would have kept him there, and was for giving him
his daughter in marriage, but as soon as he had married he set out
to fight the Achaeans with twelve ships that followed him: these he
had left at Percote and had come on by land to Ilius. He it was that
naw met Agamemnon son of Atreus. When they were close up with one
another, the son of Atreus missed his aim, and Iphidamas hit him on
the girdle below the cuirass and then flung himself upon him, trusting
to his strength of arm; the girdle, however, was not pierced, nor
nearly so, for the point of the spear struck against the silver and
was turned aside as though it had been lead: King Agamemnon caught
it from his hand, and drew it towards him with the fury of a lion;
he then drew his sword, and killed Iphidamas by striking him on the
neck. So there the poor fellow lay, sleeping a sleep as it were of
bronze, killed in the defence of his fellow-citizens, far from his
wedded wife, of whom he had had no joy though he had given much for
her: he had given a hundred-head of cattle down, and had promised
later on to give a thousand sheep and goats mixed, from the
countless flocks of which he was possessed. Agamemnon son of Atreus
then despoiled him, and carried off his armour into the host of the
Achaeans.
When noble Coon, Antenor's eldest son, saw this, sore indeed were
his eyes at the sight of his fallen brother. Unseen by Agamemnon he
got beside him, spear in hand, and wounded him in the middle of his
arm below the elbow, the point of the spear going right through the
arm. Agamemnon was convulsed with pain, but still not even for this
did he leave off struggling and fighting, but grasped his spear that
flew as fleet as the wind, and sprang upon Coon who was trying to drag
off the body of his brother- his father's son- by the foot, and was
crying for help to all the bravest of his comrades; but Agamemnon
struck him with a bronze-shod spear and killed him as he was
dragging the dead body through the press of men under cover of his
shield: he then cut off his head, standing over the body of Iphidamas.
Thus did the sons of Antenor meet their fate at the hands of the son
of Atreus, and go down into the house of Hades.
As long as the blood still welled warm from his wound Agamemnon went
about attacking the ranks of the enemy with spear and sword and with
great handfuls of stone, but when the blood had ceased to flow and the
wound grew dry, the pain became great. As the sharp pangs which the
Eilithuiae, goddesses of childbirth, daughters of Juno and
dispensers of cruel pain, send upon a woman when she is in labour-
even so sharp were the pangs of the son of Atreus. He sprang on to his
chariot, and bade his charioteer drive to the ships, for he was in
great agony. With a loud clear voice he shouted to the Danaans, "My
friends, princes and counsellors of the Argives, defend the ships
yourselves, for Jove has not suffered me to fight the whole day
through against the Trojans."
With this the charioteer turned his horses towards the ships, and
they flew forward nothing loth. Their chests were white with foam
and their bellies with dust, as they drew the wounded king out of
the battle.
When Hector saw Agamemnon quit the field, he shouted to the
Trojans and Lycians saying, "Trojans, Lycians, and Dardanian warriors,
be men, my friends, and acquit yourselves in battle bravely; their
best man has left them, and Jove has vouchsafed me a great triumph;
charge the foe with your chariots that. you may win still greater
glory."
With these words he put heart and soul into them all, and as a
huntsman hounds his dogs on against a lion or wild boar, even so did
Hector, peer of Mars, hound the proud Trojans on against the Achaeans.
Full of hope he plunged in among the foremost, and fell on the fight
