THE AUTHORSHIP OF THE SONNETS
There is no documented evidence recording of when the sonnets were all written
Therefore there is some doubt as to their true authorship!
It is, however, certain that Shakespeare had written some of the sonnets as in 1598 a certain Francis Meres made reference to Shakespeare as "his sugared sonnets among his private friends."
Meres appears to be criticising Shakespeare for fawning to his potential patrons
THE THEMES OF THE SONNETS
The themes of the Sonnets are about love
They appear to be dedicated to a handsome boy and a rival poet together with a mysterious and aloof "dark" lady that they both love
The sonnets are numbered and fall into three categories:
Sonnets 1 to 126 are addressed to or concern a young man
Sonnets 127-152 are addressed to or concern a dark lady
Sonnets 153-154 are free adaptations of two classical Greek poems
