"I command the said Don Diego (his son), or whoever shall possess the said mayorazgo (his estate), that he labor and strive always for the honor, and welfare, and increase of the city of Genoa, and employ all his abilities and means in defending and augmenting the welfare and honor of her republic, in all matters which are not contrary to the service of the church of God, and the state of the king and queen our sovereigns, and their successors."
