Cerberus quotes

   Hence loathe'  d Melancholy, Of Cerberus and blackest midnight born, In Stygian cave forlorn 'Mongst horrid shapes, and shrieks, and sights unholy, Find out some uncouth cell, Where brooding Darkness spreads his jealous wings, And the night-raven sings.

-John Milton
c.1631 L'Allegro, opening lines.
