Thus Castruccio passed from the house of Messer Antonio the priest to the house of Messer Francesco Guinigi the soldier, and it was astonishing to find that in a very short time he manifested all that virtue and bearing which we are accustomed to associate with a true gentleman. In the first place he became an accomplished horseman, and could manage with ease the most fiery charger, and in all jousts and tournaments, although still a youth, he was observed beyond all others, and he excelled in all exercises of strength and dexterity. But what enhanced so much the charm of these accomplishments, was the delightful modesty which enabled him to avoid offence in either act or word to others, for he was deferential to the great men, modest with his equals, and courteous to his inferiors. These gifts made him beloved, not only by all the Guinigi family, but by all Lucca. When Castruccio had reached his eighteenth year, the Ghibellines were driven from Pavia by the Guelphs, and Messer Francesco was sent by the Visconti to assist the Ghibellines, and with him went Castruccio, in charge of his forces. Castruccio gave ample proof of his prudence and courage in this expedition, acquiring greater reputation than any other captain, and his name and fame were known, not only in Pavia, but throughout all Lombardy. Castruccio, having returned to Lucca in far higher estimation than he left it, did not omit to use all the means in his power to gain as many friends as he could, neglecting none of those arts which are necessary for that purpose. About this time Messer Francesco died, leaving a son thirteen years of age named Pagolo, and having appointed Castruccio to be his son’s tutor and administrator of his estate. Before he died Francesco called Castruccio to him, and prayed him to show Pagolo that goodwill which he (Francesco) had always shown to HIM, and to render to the son the gratitude which he had not been able to repay to the father. Upon the death of Francesco, Castruccio became the governor and tutor of Pagolo, which increased enormously his power and position, and created a certain amount of envy against him in Lucca in place of the former universal goodwill, for many men suspected him of harbouring tyrannical intentions. Among these the leading man was Giorgio degli Opizi, the head of the Guelph party. This man hoped after the death of Messer Francesco to become the chief man in Lucca, but it seemed to him that Castruccio, with the great abilities which he already showed, and holding the position of governor, deprived him of his opportunity; therefore he began to sow those seeds which should rob Castruccio of his eminence. Castruccio at first treated this with scorn, but afterwards he grew alarmed, thinking that Messer Giorgio might be able to bring him into disgrace with the deputy of King Ruberto of Naples and have him driven out of Lucca.
