"All the world's a stage" is the phrase that begins a monologue from William Shakespeare's pastoral comedy As You Like It (believed to have been written in 1599 and first published in the First Folio in 1623), spoken by the melancholy Jaques in Act II Scene VII Line 139.
The speech compares the world to a stage and life to a play and catalogues the seven stages of a man's life, sometimes referred to as the Seven Ages of Man.
