I’ll blame my not being a native English speaker but the ooomph to his “Then, as I end the refrain, thrust home!” is somewhat lost to me. Here’s the full song:
CYRANO (Closes his eyes for an instant.)
Stop… Let me choose my rimes… Now!
Here we go—
(He suits the action to the word, throughout the following:)
Lightly I toss my hat away,
Languidly over my arm let fall
The cloak that covers my bright array—
Then out swords, and to work withal!
A Launcelot in his Lady’s hall…
A Spartacus, at the Hippodrome!..
I dally awhile with you, dear jackal,
Then, as I end the refrain, thrust home!
(The swords cross—the fight is on.)
Where shall I skewer my peacock?.. Nay,
Better for you to have shunned this brawl!—
Here, in the heart, thro’ your ribbons gay?
—In the belly, under your silken shawl?
Hark, how the steel rings musical!
Mark how my point floats, light as the foam,
Ready to drive you back to the wall,
Then, as I end the refrain, thrust home!
Ho, for a rime!.. You are white as whey—
You break, you cower, you cringe, you… crawl!
Tac!—and I parry your last essay:
So may the turn of a hand forestall
Life with its honey, death with its gall;
So may the turn of my fancy roam
Free, for a time, till the rimes recall,
Then, as I end the refrain, thrust home!
(He announces solemnly.)
Refrain:
Prince! Pray God, that is Lord of all,
Pardon your soul, for your time has come!
Beat—pass—fling you aslant, asprawl—
Then, as I end the refrain…
(He lunges; Valvert staggers back and falls into the arms of his friends. Cyrano recovers, and salutes.)
Thrust home! (I.456-484)
