Replicating Petrarca's choice in De vita solitaria, Montaigne chose to dedicate himself to the Muses. In his library, which was quite large for the period, he had wisdom formulas carved on the wooden beams. They were drawn from, amongst others, Ecclesiastes, Sextus Empiricus, Lucretius, and other classical authors, whom he read intensively. To escape fits of melancholy, he began to commit his thoughts to paper. In 1580, he undertook a journey to Italy, whose main goal was probably to cure the pain of his kidney stones at thermal resorts. The journey is related in part by a secretary, in part by Montaigne himself, in a manuscript that was only discovered during the 18th century, given the title The Journal of the Journey to Italy, and forgotten soon after. While Montaigne was taking the baths near Pisa, he learnt of his election as Mayor of Bordeaux. He was first tempted to refuse out of modesty, but eventually accepted (he even received a letter from the King urging him to take the post) and was later re-elected. In his second term he came under criticism for having abandoned the town during the great plague in an attempt to protect himself and his family. His time in office was dimmed by the wars of religion between Catholics and Protestants. Several members of his family converted to Protestantism, but Montaigne himself remained a Catholic.
