Ennius

Why should diviners seek celestial signs?
When goat or scorpion or some other beast
Comes up, then no one sees what lies before
His feet; they scan the regions of the sky.

- Achilles in Iphigenia, quoted in Cicero, The Republic I:30.

Firefly

You know what the chain of command is? It's a chain I go get and beat you with until you understand who's in ruttin' command here.

Mal: Do you want to run this ship?
Jayne: Yeah.
Mal: Well... you can't.

Howard Spring

For a moment he hung over a gulf where he and his like, all the makers of windy promises, the pedlars of paradise, swirled like a handful of inconsiderable dust. He saw with clarity that the immortal aspirations of men for freedom, truth, beauty, equality, could never know secular satisfaction, and this very fact made both the glory and the tragedy of human life.

Fame is the Spur (1943:442)

"I expect," she said, "he'll do like the rest of us. He'll do what he wants to, till the time comes for him to wonder whether it was worth doing."

(ibid, 485)

Hardie interrupted him. "The world will be busier soon. We are on the brink of war." ... "Where will you be, Hamer? I am not asking you now as your old leader. As a friend, tell me, where will you be?" ...
"It is not a thing that can be decided off-hand," said Hamer, "There are a thousand considerations."
"There is one consideration," Hardie answered. "Thou shalt not kill."
He got up wearily and held out his hand. "Good-bye," he said. "Think of me at cock-crow."

(ibid, 474)

Charles looked relieved, and smiled again. "I must confess, Father," he said, "that I still find it a bit difficult to follow a man who once demanded the Millennium and now says he'll make do with Pleasant Sunday Afternoons."
"Go on demanding the Millennium, my boy," said Hamer. "God help us when we cease to do that. But don't expect to get it, and, above all things, don't try to shove it down the people's throats. If the Millennium pays a penny in the pound, you'll be lucky...."

(ibid, 646)

"I know his views. They're an old man's views, and as such I can tolerate them and even respect them. But, remember, Charles, there's an impulsive wisdom of youth as well as a cautious wisdom of age. The views he's been giving you weren't his views when he was as young as we are now."

(ibid, 660-1)

"There's no job now for romantics. We, on our side, have got to be as dispassionate as a sanitary squad, cleaning up a dirty smell. And we've got to be quick, because it's spreading, and soon it'll poison and suffocate every decent thing and instinct. ... This is the sabre of Peterloo."
She stood for a moment looking at the light playing on the curved blade ... : the blade that had slashed the life out of the girl Emma in a Manchester street, that the old Warrior had maundered over, that Ellen had polished with bathbrick, that Hamer Shawcross had used to carve his way to the notice and applause of the people, that Jimmy Newbould had worshipped, and that Lady Lostwithiel had embalmed in velvet. ...
"I wondered why I brought it," she said, "But now I know. The world is face to face with reality. It is time to make an end of romantic gestures."
She stood away from Charles, whirled the sabre in a shining circle once round her head, then hurled it far out into the radiance of the moonlight. Silently, as if spellbound, they watched the silver splash of its fall, an Excalibur that no hand was lifted to receive.
For a moment, neither spoke; then Charles said quietly: "That was the most romantic gesture I have ever seen."

(ibid, 661)

Virgil

Being myself / No stranger to grief, I am learning to help the unhappy.

- Dido, The Aeneid, I:631-2

Trust not the horse, / You people of Teucria's land. Whatever it is, / I fear the Danaans, even when bearers of gifts.

- Lacoon, The Aeneid, II: 49-52

Just because it's good to know you've been misquoting it for years. At least, if you're me. And if 'thinking it in your head sometimes' counts as misquoting. And if you often said 'Romulans' instead of 'Greeks' anyway, in deference to Star Trek II.

Rome

Titus Pullo: Here's your money. But she'd better fuck him like Helen of Troy with her arse on fire.

Lucius Verenus: All will be well: a suitable offering was made to Triton.
Titus Pullo: Cack. If Triton can't keep us drier than this, he can suck my cock.

Sophocles

only the gods never become old, never die.
Time - dictator time - wrecks all else.
The might of the earth wastes away.
The strength of the body too.
Loyalty faith trust, all die, and treachery flourishes.
No spirit remains constant between men, between cities.
Soon
or perhaps later
the sweet becomes bitter and then loved again.
And so if between you and Thebes the days now pass in pleasantness, infinite time brings on infinite days and nights, in which, to the echo of a small word, a spear will smash the concord of past days.
And then my sleeping corpse, hidden, cold, will drink their hot blood

Oedipus, in Oedipus at Kolonos, First Episode

Wonder
at many things
But wonder most
at this thing:
Man
who
crosses the speckled sea
across winter storms ...

He has found a way
to weave the different nets
that ensnare giddy birds
trap the wild species of the plains
and catch the dwellers of the sea.
Ingenious man ...

He taught himself speech
thought light as wind
the passions that raise cities
and
how to escape the bitter shafts
of rain
the frost
the wrath of the open sky.
Nothing stops him:
he finds his way through
everything.
From death alone he sees no
way out,
even though
he discovers routes through stubborn diseases.

Second Chorus, Antigone

Time Bandits

If I'd created the world, I wouldn't have wasted time mucking about with butterflies. It'd have been lasers. 8 o'clock, day one.
