Shakespeare's sonnets
The primary source of Shakespeare’s sonnets is a quarto published in 1609 titled "Shakespeare’s Sonnets." It contains 154 sonnets, which are followed by the long poem "A Lover's Complaint". Thirteen copies of the quarto have survived in fairly good shape from the 1609 edition, which is the only edition; there were no other printings. There is evidence in a note on the title page of one of the extant copies that the great Elizabethan actor Edward Alleyn bought a copy in June 1609 for one shilling.
Same-sex intimacy
The most notable example of frequent and common instances of courtly love occurs in the writings of William Shakespeare. Shakespeare wrote many sonnets to young men that he admired, praising their beauty, intelligence and virility. He addressed sonnets 1-126 to "Fair Youth"—an individual who is commonly interpreted to be male—and later, in Sonnet 20, refers to the boy as the "master-mistress of [his] passion." Additional examples of Shakespeare writing of same-sex intimacy and courtly love are within his procreation sonnets. In these poems, Shakespeare encourages a young man to marry and have children to preserve his beauty, using loving and occasionally romantic language to communicate his message. Additionally, it is believed by many scholars that Shakespeare's famous Sonnet 18 ("Shall I compare thee to a summer's day?") is also about a man, as he dedicated his book of sonnets to an unidentified "Mr. W.H."
