With forest branches and the trodden weed.
Keats.
The rhythm of the last four examples is very common in all English verse. Occasionally the metre becomes almost ambiguous—according to its metrical context the line may be either 4-stress or 5-stress, as—
To the garden of bliss, thy seat prepar'd.
Paradise Lost, VIII, 299.
By the waters of life, where'er they sat.
Ibid., IX, 79.
In the visions of God. It was a hill.
Ibid., XI, 377.
Three-stress lines in blank verse are less frequent, but the more striking when they do occur. There is Shakespeare's famous—
To-morrow and to-morrow and to-morrow.
Milton's
Omnipotent,
Immutable, immortal, infinite,
Eternal King.
Paradise Lost, III, 372 ff.
