Iliad (Rapsodies 13 to 18)   

you are undone; you have ears that hear not, or you have lost all
judgement and understanding; have you not heard what Juno has said
on coming straight from the presence of Olympian Jove? Do you wish
to go through all kinds of suffering before you are brought back
sick and sorry to Olympus, after having caused infinite mischief to
all us others? Jove would instantly leave the Trojans and Achaeans
to themselves; he would come to Olympus to punish us, and would grip
us up one after another, guilty or not guilty. Therefore lay aside
your anger for the death of your son; better men than he have either
been killed already or will fall hereafter, and one cannot protect
every one's whole family."
With these words she took Mars back to his seat. Meanwhile Juno
called Apollo outside, with Iris the messenger of the gods. "Jove,"
she said to them, "desires you to go to him at once on Mt. Ida; when
you have seen him you are to do as he may then bid you."
Thereon Juno left them and resumed her seat inside, while Iris and
Apollo made all haste on their way. When they reached
many-fountained Ida, mother of wild beasts, they found Jove seated
on topmost Gargarus with a fragrant cloud encircling his head as
with a diadem. They stood before his presence, and he was pleased with
them for having been so quick in obeying the orders his wife had given
them.
He spoke to Iris first. "Go," said he, "fleet Iris, tell King
Neptune what I now bid you- and tell him true. Bid him leave off
fighting, and either join the company of the gods, or go down into the
sea. If he takes no heed and disobeys me, let him consider well
whether he is strong enough to hold his own against me if I attack
him. I am older and much stronger than he is; yet he is not afraid
to set himself up as on a level with myself, of whom all the other
gods stand in awe."
Iris, fleet as the wind, obeyed him, and as the cold hail or
snowflakes that fly from out the clouds before the blast of Boreas,
even so did she wing her way till she came close up to the great
shaker of the earth. Then she said, "I have come, O dark-haired king
that holds the world in his embrace, to bring you a message from Jove.
He bids you leave off fighting, and either join the company of the
gods or go down into the sea; if, however, you take no heed and
disobey him, he says he will come down here and fight you. He would
have you keep out of his reach, for he is older and much stronger than
you are, and yet you are not afraid to set yourself up as on a level
with himself, of whom all the other gods stand in awe."
Neptune was very angry and said, "Great heavens! strong as Jove
may be, he has said more than he can do if he has threatened
violence against me, who am of like honour with himself. We were three
brothers whom Rhea bore to Saturn- Jove, myself, and Hades who rules
the world below. Heaven and earth were divided into three parts, and
each of us was to have an equal share. When we cast lots, it fell to
me to have my dwelling in the sea for evermore; Hades took the
darkness of the realms under the earth, while air and sky and clouds
were the portion that fell to Jove; but earth and great Olympus are
the common property of all. Therefore I will not walk as Jove would
have me. For all his strength, let him keep to his own third share and
be contented without threatening to lay hands upon me as though I were
nobody. Let him keep his bragging talk for his own sons and daughters,
who must perforce obey him.
Iris fleet as the wind then answered, "Am I really, Neptune, to take
this daring and unyielding message to Jove, or will you reconsider
your answer? Sensible people are open to argument, and you know that
the Erinyes always range themselves on the side of the older person."
Neptune answered, "Goddess Iris, your words have been spoken in
season. It is well when a messenger shows so much discretion.
Nevertheless it cuts me to the very heart that any one should rebuke
so angrily another who is his own peer, and of like empire with
himself. Now, however, I will give way in spite of my displeasure;
