Shakespeare's Sonnets: I never saw that you did painting need

I never saw that you did painting needAnd therefore to your fair no painting set.I found (or thought I found) you did exceedThe barren tender of a poet's debt,And therefore have I slept in your reportThat you your self, being extant, well might showHow far a modern quill doth come too short,Speaking of worth, what worth in you doth grow.This silence for my sin you did impute,Which shall be most my glory, being dumb,For I impair not beauty, being mute,When others would give life and bring a tomb. There lives more life in one of your fair eyes Than both your poets can in praise devise.
