CHORUS: From jigging veins of rhyming mother-wits,
And such conceits as clownage keeps in pay,
We’ll lead you to the stately tent of war,
Where you shall hear the Scythian Tamburlaine
Threatening the world with high astounding terms,
And scourging kingdoms with his conquering sword.
View but his picture in this tragic glass,
And then applaud his fortunes as you please.

Christopher "Kit" Marlowe (1564-1593) English dramatist and poet
