All 38 plays which we recognize as Shakespeare's were published before 1634 in some form. We are very fortunate in that two friends of Shakespeare's, Heminges and Condell, decided after his death to publish a compendium of his plays.
In the absence of definitive proof to the contrary, Shakespeare must be viewed as the author of the 37 plays and 154 sonnets that bear his name. The legacy of this body of work is immense. A number of Shakespeareâs plays seem to have transcended even the category of brilliance, becoming so influential as to affect profoundly the course of Western literature and culture ever after. The Sonnets. Shakespeareâs sonnets are very different from Shakespeareâs plays, but they do contain dramatic elements and an overall sense of story. Each of the poems deals with a highly personal theme, and each can be taken on its own or in relation to the poems around it.
