In the most high and palmy state of Rome,

A little ere the mightiest Julius fell,

The graves stood tenantless, and the sheeted dead

Did squeak and gibber in the Roman streets.

William Shakespeare (1564-1616): Hamlet. Act i. Sc. 1.

Beside, 't is known he could speak Greek

As naturally as pigs squeak;

That Latin was no more difficile

Than to a blackbird 't is to whistle.

Samuel Butler (1600-1680): Hudibras. Part i. Canto i. Line 51.
