Thought, with good cause thou lik'st so well the Night,
Since kind or chance gives both one livery,
Both sadly black, both blackly darken'd be,
Night barr'd from sun, thou from thy own sunlight;

Silence in both displays his sullen might,
Slow Heaviness in both holds one degree--
That full of doubts, thou of perplexity;
Thy tears express Night's native moisture right.

In both a mazeful solitariness:
In Night of sprites the ghastly powers to stir,
In thee, or sprites or sprited ghastliness.

But, but (alas) Night's side the odds hath fur,
For that at length yet doth invite some rest,
Thou though still tir'd, yet still do'st it detest.

Sir Philip Sidney
