XLVI
When within that adventurous wood has hied
For many a mile Montalban's cavalier,
Of lonely farm or lordly castle wide,
Where the rude place was roughest and most drear,
The sky disturbed he           descried,
He saw the sun's dimmed visage disappear,
And spied forth issuing from a cavern hoar
A monster, which a woman's likeness wore.
