To heav’n aloft on ridgy waves we ride,
Then down to hell descend, when they divide.

[Tollimur in caelum curvato gurgite, et idem
subducta ad Manis imos desedimus unda.]

Now to the very shades we dip.

The curving wave one moment lifts us up
Skyward, then sinks us down as in the shades
Of death.

We are lifted skyward on the crescent wave, and again sunk deep into the nether world as the water is sucked away.
[tr. Mackail (1885)]

Upheaved upon the tossing whirl we fare unto the sky,
Then down unto the nether Gods we sink upon the wave.
[tr. Morris (1900)]

Now curls the wave, and lifts us to the sky,
Now sinks and, plunging in the gulf we lie.

We shot to skyward on the arching surge,
then, as she sank, dropped deeper than the grave.

One moment
We were in the clouds, the next in the gulf of Hell.
[tr. Humphries (1951)]

We were tossed up high on an arching surge, then down we went
In the trough as the wave fell away, down to the very Pit.

We rise to heaven on the bending wave
and, as the surge slips back, we sink again
down to the deepest Shades.

On every rolling sea
We rose to heaven, and in the abysmal trough
Sank down into the world of shades.

as the wave sank down, down we plunge to the pit of hell.
