Both men had heart for the adventure, undismayed by prophecies of mischief from devils, mermen, or sea monsters, though quaking secretly at the recollection of the sharks, which, however, rarely come close into shore. Wondrous tales were told them of things seen near the fabled grotto. Sometimes the frightened fishers had watched the glow of fire from within trembling on the waves. Beasts like crocodiles were seen to look in and out; seven times a day the entrance changed its shape and windings; at night the Sirens sang there among dead men's bones; the screams of little children in agony rang often round the rocks, and it was no uncommon thing for young fishermen to disappear in the neighbourhood of the ill-famed cavern. Many an instance could be quoted, and one tale in particular was brought up to show how mad they were who loitered on that sea. A fisherman went out to spear fish near the grotto. It was a lovely morning, and he could distinguish the shellfish creeping on the bottom, though the water was ten fathoms deep. Suddenly he saw all the fish scurry away into hiding, and just underneath his boat came swimming in concentric circles a vast sea monster, rising at each turn nearer and nearer to the surface. The fisher was uneasy, but instead of calling on the Madonna as a Christian would, he trusted in his own strength, and hurled his spear at the monster in the devil's name. He saw it strike the creature's neck, but from the wound there came such a gush of blood as clouded all the water so that he could see nothing. He thought joyfully that he had killed the fish; but the thong of his spear hung slack, and when he pulled it in the point of the harpoon was gone—not broken off, but fused, as if it had been thrust into a furnace!
The poor fisherman, terrified to death, dropped the spear and seized his oars, longing only to get away from that accursed place. But row as he might he could not progress. His boat went round in circles, as the sea monster had swum, and finally stood still as if anchored, while out of the reddened water rose a bloodstained man, with the spear sticking in his breast, and threatened the fisher with his fist. The poor man sank down fainting, and when he came to life again he was being tended by his friends at the Marina of Capri. For three days he was dumb. When he could speak and tell what had befallen him he began to shrivel up. First his right hand withered, then his arms and legs, till finally, when he died, he had lost the aspect of a man, and was like nothing but a bundle of dried herbs in an apothecary's shop.
Such were the tales with which the Capriotes sought to dissuade Kopisch from paying heed to the suggestions of Pagano, but in vain. Early in the morning the party started, having with them Angelo Ferraro, a boatman, with a second boat in which they had packed a small stove, with all the materials necessary for kindling a fire. When they came to the low entrance of the cave not one of them was quite at ease, and Kopisch, who was in the water first, begged Angelo, the boatman, for a fresh assurance that sharks never came between the rocks. Angelo was labouring to kindle his fire, and gave a hasty confident reply, which provoked the German to the natural reflection, "It's all very well for him to be sure. His legs are in the boat!"
But when the resinous wood shavings caught and blazed up brightly all fear was gone. Angelo pulled in under the low archway, pushing the smaller boat with the lighted stove before him. Close behind came Kopisch, Pagano, and a second German traveller, half blinded by the smoke which blew back in their faces, and full of natural excitement and anxiety concerning what might befall them in this bold quest. For a time they could see nothing save a dim, high vault; but when Kopisch turned to look for his companions he, first of all men of our age and knowledge, saw that sight which for absolute beauty and wonder has no superior in all the world.
"What a panic seized me," he says himself, "when I saw the water under me like blue flames of burning spirits of wine! I leapt upwards, for, half blinded as I was by the fire in the boat, I thought first of a volcanic eruption. But when I felt the water cold I looked up at the roof, thinking the blue light must come from above. But the roof was closed.... The water was wonderful, and when the waves were still, it seemed as if I were swimming in the invisible blue sky...."
I have told this adventure at some length because, in mere justice, Kopisch and Pagano ought not to be forgotten by the crowds of pleasure seekers who visit Capri, and for whom, however much or little they may take pleasure in the other immense beauties of the island, the Blue Grotto still remains the chief delight. It may not be necessary to claim for Kopisch that he was indeed first of all men to see its marvellous beauty; nor even that, but for his bold adventure, its low gateway would have remained closed to all the world. Discoveries such as this are made at their appointed time, and Kopisch may perhaps have had precursors. But it remains true that his audacity first threw wide the gate for us; and for my part I acknowledge gladly a deep debt of gratitude.
No wise man goes to the Blue Grotto from the steamer by which he travels from Naples or Sorrento. When one has crossed the ocean, and journeyed thousands of miles, to see a sight so wonderful, why should one be content to hurry round it in the few minutes given by a boatman eager for other fares? There is but one way to see the Blue Grotto, and that is by hiring a boat at the Marina on a still, sunny morning, bargaining carefully that there shall be no compulsion to leave before one wishes. Then as the boatman rows on slowly beneath the luxuriant vineyards and the green slopes of the saddle of the island, he will point out the baths of the Emperor Tiberius, low down by the shore, indeed, partly covered by the clear green water, and will go on to talk of the strange life led by the imperial recluse, who studded the island with palaces and left it teeming with unsolved mysteries. Twelve villas he built, so says Tacitus, upon this narrow space, and in these solitary palaces by cliff and shore he lived a life of nameless tyranny and wickedness. Who can tell the uses of the strange masses of broken masonry which one finds in climbing up and down the lonely cliff paths? With what object did he build tower and arched vault in spots where only sea-birds could have the fancy for alighting? What secret chambers may not still be hidden in these ruins! What passages leading deep into caverns of the hillside! What mysteries! What treasures for those who have the heart and courage of the German artist! Such are the suggestions of the brown-faced boatman bending towards me across his oars, while in a hushed whisper he points out now one and now another chasm of the limestone which gives access, so he tells me, to a cavern of unmeasured size. And still, as he talks eagerly and low, the sheer cliff rises higher and darker overhead; for the saddle of the island is long past, the towering precipices of Monte Solaro are above me, and high up on some eyrie which the sight straining from the water cannot reach is the white mountain town of Anacapri.
Presently the coast-line sinks to a more moderate height. The tower of Damecuta is seen ahead, and below it a stair, cut in the face of the rock, leads down to a low arched opening, through which the blue sea is washing in and out. A couple of women in gay dresses are sitting in the shade upon the stair. A few boats are rocking on the blue water, strangely, intensely blue, even in the morning shadow which the cliffs fling out across the sea. It was not the rich, royal colour which one may see about the shores of western England, nor yet the exquisite soft turquoise which glows by all the bays and headlands of this coast, but a darker and more watery blue, verging on indigo rather than on any other single colour.
The boat approached the opening. The boatman, warning me to lie flat in the stern, shipped his oars, grasped a chain which was fastened to the rock, and, at the lowest point of the wet, winding entrance, flung himself backward on my body, while the boat shot into what for an instant seemed a moonlit darkness. But on struggling up erect I became conscious of a strange, milky radiance, which grew and brightened as the sight adjusted itself, until I saw that the waves washing round the boat were of a silvery blue, which is like nothing else, lambent, incandescent, flashing with the softest glow imaginable. One thinks of the shimmering flashes in the heart of an opal, of the flame of phosphorus, of the most delicate colour on a blue bird's throat—there is no similitude for that which has no match, nothing else upon the earth which is not gross when set beside these waves of purest light, impalpable, unsubstantial, and radiantly clear. "Che colore?" I asked in wonder; and the boatman, no less awed by the strange beauty, answered very low, "Il cielo," and sat silent, stirring his oar gently, so as to make spouts of light among the blue reflections.
The roof of the Blue Grotto, low-spreading near the entrance, rises at the centre into a domed vault. It is not dark—nowhere in the grotto is it dark—it is neither light nor dark, but blue; blue pervades the air, and plays about the crannies of the roof like flame, far paler than the sea, yet quick and living.
