Aristophanes, The Frogs

XANTHIAS

By the Lord Zeus,
If ever I was here before, if ever
I stole one hair's-worth from you, let me die! And now I'll make you a right noble offer, Arrest my lad: torture him as you will, And if you find I'm guilty, take and kill me.

AEACUS

Torture him, how?

XANTHIAS

In any mode you please.
Pile bricks upon him: stuff his nose with acid: Flay, rack him, hoist him; flog him with a scourge of prickly bristles:
only not with this, A soft-leaved onion, or a tender leek.
