Four cedar beams, exactly wrought to shape,

Lie, near each brink, across the dreadful gap;

Four other beams of equal size extend

Towards the heav’ns, and centre in one end;

To which a chain, wrought out of Ætna’s fire,

Pass’d through an aperture a cubit higher

(Its length ten leagues, and polish’d every link);

One end in hell, and one upon the brink,

Upon the side whereat the funeral train

Would yield the corpse; there, on the sacred plain,
