CII When he perceives the first of no avail, The knight returns to deal a better blow; The orc, who sees the shifting shadow sail Of those huge pinions on the sea below, In furious heat, deserts his sure regale On shore, to follow that deceitful show: And rolls and reels behind it, as it fleets. Rogero drops, and oft the stroke repeats. CIII As eagle, that amid her downward flight, Surveys amid the grass a snake unrolled, Or where she smoothes upon a sunny height, Her ruffled plumage, and her scales of gold, Assails it not where prompt with poisonous bite To hiss and creep; but with securer hold Gripes it behind, and either pinion clangs, Lest it should turn and wound her with its fangs; CIV So the fell orc Rogero does not smite With lance or faulchion where the tushes grow, But aims that 'twixt the ears his blow may light; Now on the spine, or now on tail below. And still in time descends or soars upright, And shifts his course, to cheat the veering foe: But as if beating on a jasper block, Can never cleave the hard and rugged rock. CV With suchlike warfare is the mastiff vext By the bold fly in August's time of dust, Or in the month before or in the next, This full of yellow spikes and that of must; For ever by the circling plague perplext, Whose sting into his eyes or snout is thrust: And oft the dog's dry teeth are heard to fall; But reaching once the foe, he pays for all. CVI With his huge tail the troubled waves so sore The monster beats, that they ascend heaven-high; And the knight knows not if he swim, or soar Upon his feathered courser in mid sky; And oft were fain to find himself ashore: For, if long time the spray so thickly fly, He fears it so will bathe his hippogryph, That he shall vainly covet gourd or skiff. CVII He then new counsel took, and 'twas the best, With other arms the monster to pursue; And lifting from his shield the covering vest, To dazzle with the light his blasted view. Landward towards the rock-chained maid he pressed, And on her little finger, lest a new Mischance should follow, slipt the ring, which brought The enchantment of the magic shield to nought. CVIII I say the ring, which Bradamant, to free Rogero, from Brunello's hand had rent, And which, to snatch him from Alcina, she Had next to India by Melissa sent. Melissa (as before was said by me), In aid of many used the instrument; And to Rogero this again had born; By whom 'twas ever on his finger worn. CIX He gave it now Angelica; for he Feared lest the buckler's light should be impaired, And willed as well those beauteous eyes should be Defended, which had him already snared. Pressing beneath his paunch full half the sea, Now to the shore the monstrous whale repaired: Firm stood Rogero, and the veil undone, Appeared to give the sky another sun.
