Il Penseroso (The Serious Man) is a vision of poetic melancholy by John Milton, first found in the 1645/1646 quarto of verses The Poems of Mr. John Milton, both English and Latin, published by Humphrey Moseley. It was presented as a companion piece to L’Allegro, a vision of poetic mirth. The speaker of this reflective ode dispels 'vain deluding Joys' from his mind in a ten-line prelude, before invoking 'divinest Melancholy' to inspire his future verses. The melancholic mood is idealised by the speaker as a means by which to 'attain / To something like prophetic strain,' and for the central action of Il Penseroso - which, like L’Allegro, proceeds in couplets of iambic tetrameter.
