SONNET XX
A woman's face with Nature's own hand painted
Hast thou, the master-mistress of my passion;
A woman's gentle heart, but not acquainted
With shifting change, as is false women's fashion;
An eye more bright than theirs, less false in rolling, 5
Gilding the object whereupon it gazeth;
A man in hue, all 'hues' in his controlling,
Much steals men's eyes and women's souls amazeth.
And for a woman wert thou first created;
Till Nature, as she wrought thee, fell a-doting, 10
And by addition me of thee defeated,
By adding one thing to my purpose nothing.
But since she prick'd thee out for women's pleasure,
Mine be thy love and thy love's use their treasure. 14
SONNET CXXXVIII
When my love swears that she is made of truth
I do believe her, though I know she lies,
That she might think me some untutor'd youth,
Unlearned in the world's false subtleties.
Thus vainly thinking that she thinks me young, 5
Although she knows my days are past the best,
Simply I credit her false speaking tongue:
On both sides thus is simple truth suppress'd.
But wherefore says she not she is unjust?
And wherefore say not I that I am old? 10
O, love's best habit is in seeming trust,
And age in love loves not to have years told:
Therefore I lie with her and she with me,
And in our faults by lies we flatter'd be. 14
Happy analyzing
hehe.
