How does john milton link the mirth of "l'allegro" with melancholy of "il pensoroso" in these two excerpts?

John Milton link the mirth of "L'Allegor" with the melancholoy of "Il Pensoroso" by talking about it reflective ode that dispels "vain deluding Joys" from the mind of Milton. Il Penseroso (or The Serious Man) is considered as a vision of poetic melancholy of John Milton where it was presented as a companion with L'Allegor. Both are visions of poetic mirth. The style that employs in L'Allegro and Il Penseroso precludes the poem's summary of dramatic action. It is rendered in ambiguous to critics.
