There no breeze exists to propel the ship forward;
Deadening is this sluggish sea's still vapor.
Many seaweeds grow in the troughs of the billows,
Slowing the ship like bushes, he says, thus showing
Here to no great depth the sea descends, and
Here the water barely covers the bottom.
Here the beasts of the sea move slowly wandering,
And among the sluggishly creeping vessels
Languidly swim the great monsters.
Himilco, ca. 533-500 B.C., writing of his sea expeditions.
