While here and there two lofty crags arise,
Whose towers, far out at sea, salute the sailor’s eyes.
Safe sleep the silent seas beneath; above,
Black arching woods o’ershade the circled scene:
Within, a grotto opens, in the grove,
Pleasant with flowers, with moss, with ivies green,
And waters warbling in the depths unseen;
Needed nor twisted rope nor anchor there
For weary ships.”
—Tasso, Jerusalem Delivered.
