Biographic fact in the ‘dedicatory’ sonnets.
Amid the borrowed conceits and poetic figures of Shakespeare’s sonnets there lurk suggestive references to the circumstances in his external life that attended their composition. If few can be safely regarded as autobiographic revelations of sentiment, many of them offer evidence of the relations in which he stood to a patron, and to the position that he sought to fill in the circle of that patron’s literary retainers. Twenty sonnets, which may for purposes of exposition be entitled ‘dedicatory’ sonnets, are addressed to one who is declared without periphrasis and without disguise to be a patron of the poet’s verse (Nos. xxiii., xxvi., xxxii., xxxvii., xxxviii., lxix., lxxvii.-lxxxvi., c., ci., cvi.) In one of these—Sonnet lxxviii.—Shakespeare asserted:
So oft have I invoked thee for my Muse
And found such fair assistance in my verse
As every alien pen hath got my use
And under thee their poesy disperse.
Subsequently he regretfully pointed out how his patron’s readiness to accept the homage of other
poets seemed to be thrusting him from the enviable place of pre-eminence in his patron’s esteem.
