'Time passed, I know not whether months or years; _3055
For day, nor night, nor change of seasons made
Its note, but thoughts and unavailing tears:
And I became at last even as a shade,
A smoke, a cloud on which the winds have preyed,
Till it be thin as air; until, one even, _3060
A Nautilus upon the           played,
Spreading his azure sail where breath of Heaven
Descended not, among the waves and whirlpools driven.
