During his holidays this year, his uncle took him to the Opera for the first time, where he heard the Mercato di Malmantile. The music produced a most extraordinary effect upon him, and for several weeks afterwards he remained immersed in a strange but not unpleasing melancholy, followed by an absolute loathing of his usual studies. Music all through life affected him most powerfully, and he states that his tragedies were almost invariably planned by him when under its influence. It was about this time that he composed his first sonnet, which was made up of whole or mutilated verses of Metastasio and Ariosto, the only two Italian poets of whom he knew any thing. It was in praise of a certain lady to whom his uncle was paying his addresses, and whom he himself admired. Several persons, including the lady herself, praised it, so that he already fancied himself a poet. His uncle, however, a military man, and no votary of the Muses, laughed at him so much, that his poetical vein was soon dried up, and he did not renew his attempts in the line till he was more than twenty-five years old. "How many good or bad verses did my uncle suffocate, together with my first-born sonnet!"

He next studied physics and ethics—the former under the celebrated Beccaria, but not a single definition remained in his head. These studies, however, as well as those in civil and canon law, which he had commenced, were interrupted by a violent illness, which rendered it necessary for him to have his head shaved, and to wear a wig. His companions, at first, tormented him greatly about this wig, and used to tear it from his head; but he soon succeeded in appeasing the public indignation, by being always the first to throw the unhappy ornament in question up in the air, calling it by every opprobrious epithet. From that time he remained the least persecuted wig-wearer among the two or three who were in this predicament.

He now took lessons on the piano, and in geography, fencing, and dancing. He imbibed the most invincible dislike to the latter, which he attributed to the grimaces and extraordinary contortions of the master, a Frenchman just arrived from Paris. He dates from this period that extreme hatred of the French nation which remained with him through life, and which was one of the strangest features in his character. His uncle died this year (1763), and as he was now fourteen, the age at which, by the laws of Piedmont, minors are freed from the care of their guardians, and are placed under curators, who leave them masters of their income, and can only prevent the alienation of their real estates, he found himself possessed of considerable property, which was still farther increased by his uncle's fortune. Having obtained the degree of master of arts, by passing a public examination in logic, physics, and geometry, he was rewarded by being allowed to attend the riding-school, a thing he had always ardently desired. He became an expert horseman, and attributes to this exercise the recovery of his health, which now rapidly improved.

"Having buried my uncle, changed my guardian into a curator, obtained my master's degree, got rid of my attendant Andrea, and mounted a steed, it is incredible how proud I became. I told the authorities plainly that I was sick of studying law, and that I would not go on with it. After a consultation, they determined to remove me into the first apartment, which I entered on the 8th May, 1763."

He now led an extremely idle life, being little looked after. A crowd of flatterers, the usual attendants upon wealth, sprung up around him, and he indulged in amusements and dissipations of every kind. A temporary fit of industry, which lasted for two or three months, came over him, and he plunged deeply into the thirty-six volumes of Fleury's Ecclesiastical History. Soon, however, he resumed his old course, and conducted himself so badly that the authorities found it necessary to place him under arrest, and he remained for some months a prisoner in his own apartment, obstinately refusing to make any apology, and leading the life of a wild beast, never putting on his clothes, and spending most of his time in sleep. He was at length released, on the occasion of his sister Giulia's marriage to the Count Giacinto di Cumiana, in May, 1764.

On regaining his former position he bought his first horse, and soon afterwards another, on the pretence of its being delicate. He next purchased two carriage horses, and went on thus till in less than a year he had eight in his possession. He also had an elegant carriage built for him, but used it very seldom, because his friends were obliged to walk, and he shrunk from offending them by a display of ostentation. His horses, however, were at the service of all, and as his love for them could not excite any feelings of envy, he took the greatest delight in them.

It was now that he first felt the symptoms of love, excited by a lady who was the wife of an elder brother of some intimate friends of his, to whom he was on a visit. His transient passion, however, soon passed away, without leaving any trace behind it. The period had now arrived for his leaving the academy, and in May, 1766, he was nominated ensign in the provincial regiment of Asti, which met only twice a-year for a few days, thus allowing ample opportunity for doing nothing; the only thing, he says, he had made up his mind to do. But he soon got tired of even this slight restraint. "I could not adapt myself to that chain of graduated dependence which is called subordination, and which although the soul of military discipline, could never be the soul of a future tragic poet." He therefore obtained permission, though with great difficulty, to accompany an English Catholic tutor, who was about to visit Rome and Naples with two of his fellow-students. He chooses this moment for commencing the epoch of youth, which he describes as embracing ten years of travel and dissipation.

On reaching Milan, the travellers visited the Ambrosian library.

"Here the librarian placed in my hands a manuscript of Petrarch, but, like a true Goth, I threw it aside, saying it was nothing to me. The fact was, I had a certain spite against the aforesaid Petrarch; for having met with a copy of his works some years before, when I was a philosopher, I found on opening it at various places by chance that I could not understand the meaning in the least; accordingly I joined with the French and other ignorant pretenders in condemning him, and as I considered him a dull and prosy writer, I treated his invaluable manuscript in the manner above described."

At this time he always spoke and wrote in French, and read nothing but French books.
