The steamer slips on noiselessly as ever. Procida falls away into the background, with its old brown town clinging to the seaward face of a precipitous cliff; and I can look down the Bay of Baiæ, where in old Roman days every woman who went in a Penelope came out a Helen, and almost catch a glance at Cumæ, where Dædalus put off his weary wings after that great flight from Crete which no man since has contrived to imitate. There lies the Gate of Hell down which Æneas plunged in company with the Sibyl; and round it all the land of the Phlegræan fields, heaving and steaming with volcanic fires. There too is the headland of Posilipo, where Virgil dwelt and where he wrought those enchantments concerning which I shall have much to say hereafter; for though Virgil is a poet to the world at large, he is a magician in the memory of the Neapolitans. And who shall say their tradition is not true? Next, sweeping round towards my right hand in a perfect curve, comes the shore of the Riviera di Chiaia, once a pleasant sandy beach, broken midway by the jutting rock and island on which stood the church and monastery of San Lionardo. It is long since church and island disappeared, and few of those gay Neapolitans who throng the Via Caracciolo, that fine parade which now usurps the whole seafront from horn to horn of the bay, could even point out where it stood. In these days the whole shore is embowered in trees and gardens skirting the fine roadway; and there stands the wonderful aquarium, which has no equal in the world, and where the wise will spend many afternoons and yet leave its marvels unexhausted.
