As I stepped out on the belvedere the sun was dropping fast towards Posilipo, and wide flashes of gold were spreading over all the cup-shaped bay. Far out at sea, between the two horns of the gulf, the dark peaks of Capri caught the light, and presently the glow blazed more brightly in the west, and all the shores where Sorrento lies began to quiver softly in the sunset. Vesuvius was grim and black; a pillar of dark smoke mounted slowly from its summit, and stretched across the paling sky like a banner floating defiantly from some tall citadel. Deep down beneath me lay the white city, a forest of domes and house-fronts which seemed at first impenetrable. But ere long the royal palace detached itself from the other buildings, and I could distinguish Castel Nuovo, with its old round towers, looking very dark and grim, while on the left a forest of domes and spires rose out of the densely crowded streets which have known so many masters and have allured conquerors from lands so very far away. A faint brown haze crept down from the hilltops, the first touch of evening chilled the air, but the seaward sky was marvellously clear, and the wide bay gleamed with gold and purple lights. CHAPTER II THE ANCIENT MARVELS OF THE PHLEGRÆAN FIELDS It is a morning of alternate sun and shadow. The clouds are flying low across the city, so that now one dome and now another flashes into light and the orange groves shine green and gold among the square white houses. All the high range of the Sorrento mountains lies in shadow, but on the sea the colours are glowing warm and bright, here a tender blue, there deepening into grey, and again, nearer into shore, a marvellous rich tint which has no name, but is azure and emerald in a single moment. Away across the crescent of the gulf a crowd of fishing boats are putting forth from Torre del Greco or Torre dell' Annunziata. Even at this distance one can see how they set their huge triangular sails and scatter, some one way, some another, searching each perhaps for his favourite volcanic shoal; for the largest fish lurk always in the hollows of those lava reefs which have from time to time burst out of the bottom of the bay. Some, perhaps, are sailing for the coral fishery upon the coast of Africa, to which great numbers go still in this month of April out of all the harbours beneath Vesuvius, though the profits are not what they were, and the trade is falling upon evil days. As for the mountain, he has cleared himself of clouds, and from his summit a heavy coil of smoke uncurls itself lazily and spreads like a pennant stretching far across the sky.
