The convent was the only refuge from violence, and Bruno, either from religious enthusiasm, or in order to be able to devote himself to study, became a friar at the age of fifteen. There, in the quiet cloister of the convent of St. Dominic at Naples, his mind was nourished and his intellect developed; the cloistral and monkish education failed to enslave his thought, and he emerged from this tutelage the boldest and least fettered of philosophers. Everything about this church and this convent, famous as having been the abode of Thomas Aquinas, was calculated to fire the enthusiasm of Bruno's soul; the leisure and quiet, far from inducing habits of indolence, or the sterile practices of asceticism, were stimulants to austere study, and to the fervour of mystical speculations. Here he passed nearly thirteen years of early manhood, until his intellect strengthened by study he began to long for independence of thought, and becoming, as he said himself, solicitous about the food of the soul and the culture of the mind, he found it irksome to go through automatically the daily vulgar routine of the convent; the pure flame of an elevated religious feeling being kindled in his soul, he tried to evade the vain exercises of the monks, the puerile gymnastics, and the adoration of so-called relics.

A few days after his arrival in Rome he learned that instructions for his arrest had been forwarded from Naples; he tarried not, but got away secretly, throwing aside the monk's habiliments by the way. He wandered for some days about the Roman Campagna, his destitute condition proving a safeguard against the bands of brigands that infested those lands, until arriving near Civita Vecchia, he was taken on board a Genoese vessel, and carried to the Ligurian port, where he hoped to find a refuge from his enemies; but the city of Geneva was devastated by pestilence and civil war, and after a sojourn of a few days he pursued once more the road of exile. Seeking for a place wherein he might settle for a short time and hide from his pursuers, he stayed his steps at Noli, situated at a short distance from Savona, on the
