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 all, Mr. Shakespeare wrote between 37 and 40 plays, depending on whom you ask. Some he wrote in collaboration. âPericles, Prince of Tyre,â for instance, does not make sense as the work of a single playwright; in fact, it makes little sense at all.
