By October he was already in Lucca, employed as preceptor by the nobleman Niccolò di Silvestro Arnolfini.
The Republic of Lucca was stirred up with religious and political reform movements.
The Gonfaloniere, Francesco Burlamacchi, hoped to end the dominion of Cosimo I de' Medici and the temporal power of the Church in that region, and to create a federation of free Tuscan cities.
To this end he advocated to the Comune the formation of a special militia which he should lead.
Burlamacchi himself was not Lutheran, but the various protestant groups in the city (reflecting its mercantile and intellectual exchange with Germany) might approve his project.

When Curio arrived, there was already a large active colony of Italian internal religious exiles, including Paolo Lazise, Celso Martinengo, the jewish convert Emanuele Tremellio, Peter Martyr and Girolamo Zanchi.
From June 1541 Peter Martyr was Prior of the Basilica of San Frediano, a position of considerable authority: he held a school for reading in the Gospels, the letters of St Paul, and Saint Augustine, and encouraged direct reading and understanding of the Bible.
His lessons were attended by young students and learned elders such as Curio himself and the humanist Francesco Robortello alike.

Cardinal Bartolomeo Guidiccioni, non-resident Bishop of Lucca newly appointed to the Roman Inquisition, in a letter to the Senate of Lucca dated 22 July 1542 denounced that Evangelic group and that "Cellio who dwells in the house of Master Niccolò Arnolfini".
Burlamacchi's plan to subject the citizen power to his political and religious reforms was exposed.
At the end of July Peter Martyr, the young disciple Giulio Terenziano, Lazise and Tremellius fled, while Curio took refuge at first in Pisa, where the Inquisition tried to catch up with him.
Cardinal Alessandro Farnese, on 26 August 1542, sent to Duke Cosimo from Rome the warrant for the arrest for that "wretched spirit called Celio of Turin", who however had already taken the road to Switzerland and was received, at the recommendation of the theologian Heinrich Bullinger, in the Academy of Lausanne.
