Covered from base to summit with fume-weed, lentisk, aromatic cistus, and every plant that loves the sun, the wind and the salt foam of the Mediterranean, the huge solitary cliff rises majestically from the deep blue water. Whether viewed in brilliant sunshine under a cloudless sky, or in foul weather, when the sea is hurling its waves over the stone causeway that connects the isolated crag with the little city of Ischia, the first sight of this historic castle is singularly impressive. Nor is its grandeur lessened on a near approach, for the ascent to its topmost tower takes us through a labyrinth of staircases and mysterious subterranean passages, through vaulted chambers and curious hanging gardens to an airy platform, which commands a glorious view in every direction over land and sea. Built by Alphonso V. of Aragon in the fifteenth century, this massive pile, half-fortress and half-palace, is famous in Italian annals for its long association with the noble poetess Vittoria Colonna, Marchioness of Pescara. Born in the old Castle of Marino, near Rome, one of the strongholds of the great feudal house of Colonna, the poetess, who was great-great-niece to Pope Martin V., was betrothed in her infancy at the instigation of King Ferdinand of Naples to the youthful heir of the d’Avalos family, hereditary governors of the island of Ischia. The elder sister of Vittoria’s affianced husband, Constance d’Avalos, the widowed Duchess of Francavilla, was the “châtelaine” of Ischia during her brother’s minority, so that it was but natural that his Colonna bride-elect should be sent to dwell with Constance in this castle. Here Vittoria under her sister-in-law’s excellent tutelage grew up to womanhood amidst the intellectual atmosphere of the Italian Renaissance, and here she was trained to develop into one of the most learned, the most interesting and the most attractive figures that all Italy produced at this period. Childless in her early marriage at eighteen, and with her husband frequently, not to say usually, engaged in military expeditions on the mainland, Vittoria had every opportunity of cultivating her mind and of filling her sea-girt palace with men of genius. The poets Cariteo and Bernado Tasso (the father of Torquato Tasso), were frequent visitors at this “Superbo scoglio, altaro e bel ricetto, Di tanti chiari eroi, d’ imperadori, Orde raggi di gloria escono fuori, Ch’ ogni altro lume fan scuro e negletto.”
