Drop serene

Thee I re-visit now with bolder wing, Escap't the STYGIAN Pool, though long detain'd In that obscure sojourn, while in my flight Through utter and through middle darkness borne With other notes then to th' ORPHEAN Lyre I sung of CHAOS and ETERNAL NIGHT, Taught by the heav'nly Muse to venture down The dark descent, and up to reascend, Though hard and rare: thee I revisit safe, And feel thy sovran vital Lamp; but thou Revisit'st not these eyes, that rowle in vain To find thy piercing ray, and find no dawn; So thick a drop serene hath quencht thir Orbs, Or dim suffusion veild.
