April 23rd is generally considered to be a good day to celebrate the birth of England’s greatest poet and playwright, William Shakespeare. This is partly because there are no records of his birth—although he was baptized on April 26—and partly because he died on April 23 (and April 23 is St. George’s day, patron saint of England), so there is a pleasing, almost poetic symmetry about the way the dates line up.
Shakespeare's work includes 38 plays, 2 narrative poems, 154 sonnets, and a variety of other poems. No original manuscripts of Shakespeare's plays are known to exist today. It is actually thanks to a group of actors from Shakespeare's company that we have about half of the plays at all. They collected them for publication after Shakespeare died, preserving the plays. These writings were brought together in what is known as the First Folio ('Folio' refers to the size of the paper used). It contained 36 of his plays and none of his poetry.
