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.
Shakespeare evidently named his son after his recusant neighbor and friend Hamnet Sadler, who was still alive in March 1616 when Shakespeare drew up his will and left 26 shillings, 8 pence to âHamlett Sadlerâ¦to buy him a ringe.â. Writing a play about Hamlet, in or around 1600, may not have been Shakespeareâs own idea.
