Which of these four excerpts from John Milton's poetry is in blank verse?
Restore us, and regain the blissful Seat,
Sing Heav'nly Muse, that on the secret top
Of Oreb, or of Sinai, didst inspire
That Shepherd, who first taught the chosen Seed,
In the Beginning how the Heav'ns and Earth
(from Paradise Lost)
. . .
B) In Heav'n yclept Euphrosyne,
And by men, heart-easing Mirth,
Whom lovely Venus at a birth
With two sister Graces more
To ivy-crowned Bacchus bore
(from "L'Allegro")
. . .
C) Dissolve me into extasies,
And bring all Heav'n before mine eyes.
And may at last my weary age
Find out the peaceful hermitage,
The Hairy Gown and Mossy Cell,
(from "Il Penseroso")
. . .
D) Where I may sit and rightly spell
Of every Star that Heav'n doth shew,
And every Herb that sips the dew;
Till old experience do attain
To somthing like Prophetic strain.
(from "Il Penseroso")
