Judge Nino hearing this, and seeing that he was not well able to
defend himself, left the city and went to his castle of Calci, and
allied himself with the Florentines and Lucchese to make war against
Pisa. Count Ugolino, before the departure of Judge Nino, to the end he
might hide his treachery when he had planned the banishment of the
judge, departed from Pisa, and went to one of his manors in the
country, which was called Settimo. When he heard of the departure of
Judge Nino, he returned to Pisa with great rejoicing; and the Pisans
