Already, ere my best speed could prevent, The aidless innocent lady, his wished prey; Who gently asked if he had seen such two, Supposing him some neighbour villager. Longer I durst not stay, but soon I guessed Ye were the two she meant; with that I sprung Into swift flight, till I had found you here; But further know I not. _Second Brother._ O night and shades, 580 How are ye joined with hell in triple knot Against the unarmed weakness of one virgin, Alone and helpless! Is this the confidence You gave me, brother? _Elder Brother._ Yes, and keep it still; Lean on it safely; not a period Shall be unsaid for me. Against the threats Of malice or of sorcery, or that power Which erring men call Chance, this I hold firm: Virtue may be assailed, but never hurt, Surprised by unjust force, but not enthralled; 590 Yea, even that which Mischief meant most harm Shall in the happy trial prove most glory. But evil on itself shall back recoil, And mix no more with goodness, when at last, Gathered like scum, and settled to itself, It shall be in eternal restless change Self-fed and self-consumed. If this fail, The pillared firmament is rottenness, And earth's base built on stubble. But come, let's on! Against the opposing will and arm of Heaven 600 May never this just sword be lifted up; But, for that damned magician, let him be girt With all the grisly legions that troop Under the sooty flag of Acheron, Harpies and Hydras, or all the monstrous forms 'Twixt Africa and Ind, I'll find him out, And force him to return his purchase back, Or drag him by the curls to a foul death, Cursed as his life. _Spirit._ Alas! good venturous youth, I love thy courage yet, and bold emprise; 610 But here thy sword can do thee little stead. Far other arms and other weapons must Be those that quell the might of hellish charms. He with his bare wand can unthread thy joints, And crumble all thy sinews. _Elder Brother._ Why, prithee, Shepherd, How durst thou then thyself approach so near As to make this relation?
