Maids on the shore, with marble-white feet tread,

So far 'tis safe; but to go farther, dread.

Let others tell how winds fierce battles wage,

How Scylla's and Charybdis' waters rage;

And with what rock the feared Ceraunia threat;

In what gulf either Syrtes have their seat.20

Let others tell this, and what each one speaks

Believe; no tempest the believer wreaks.[298]

Too late you look back, when with anchors weighed,

The crookèd bark hath her swift sails displayed.
