The characters of Inglesant and his wife were of such a nature as most effectively to produce and aggravate this sleepless uneasiness. Upon Lauretta’s lenient and gracious, if somewhat pleasure-loving disposition, the impression of the unkindness she had experienced from her brother faded without leaving a trace, and she thought only of some pleasant, long-past incidents, when she had been a pretty, engaging child; whilst the life of romance and excitement, combined with a certain spiritual Quixotism, which Inglesant had so long followed, had rendered any other uncongenial to him, and it required little persuasion to induce him to re-enter upon it. But there were other causes at work which led to the same result. For many weeks a sultry wind had, without variation, passed over the south of Italy, laden with putrid exhalations from the earth, and by its sullen steadiness causing stagnation in the air. It would be difficult to describe the terrible effect upon the mind and system of the long continuance of such a state of the atmosphere. A restless fear and depression of spirits prepared the body for the seeds of disease, and the contagion, which was not perhaps generated in the atmosphere, was carried by it with fearful rapidity. The plague struck down its victims at once in city and in country, and spared no rank nor condition of life. Then all bond of fellowship and of society was loosened, strange crimes and suspicions,—strange even to that land of crime and treachery,—influenced the lives and thoughts of all men. Innocent persons were hunted to death, as poisoners and spreaders of infection; the terrors of the grave broke through the forms of artificial life, and the depravity of the heart was exposed in ghastly nakedness, as the bodies of the dead lay unburied by the waysides. The Castello di San Georgio, standing on the summit of a breezy hill, in a thinly-peopled district, was as safe a refuge as could perhaps be found, and, if uneasiness of mind could have been banished, might have been a happy one. Three hundred years before, in the child-like unconsciousness of spiritual conflict which the unquestioned rule of Rome for so long produced, it had been possible, in the days of Boccacio, for cultivated and refined society to shut itself up in some earthly paradise, and, surrounded by horrors and by death, to spend its days in light wit and anecdote, undisturbed in mind, and kept in bodily health by cheerful enjoyment; but the time for such possibilities as these had long gone by. A mental trouble and uneasiness, which pervaded the whole of human life at the most quiet times, gave place, at such periods of dread and fear, to an intolerable restlessness, which altogether precluded the placid enjoyment of the present, however guarded and apparently secure.
