This Constance was the mother--we shall not say of Frederick II. who was long king of the Roman Empire,--but rather of Frederick who brought the said Empire to destruction, as will appear fully in his deeds. When Tancred was dead then, the kingdom passed to his son William, young in years and in wisdom; but Henry having entered the kingdom with his army the year of Christ 1197, made a false truce with the young King William, and having taken him by fraud and secretly into Suabia, few knowing thereof, he sent him into banishment with his sister, and having caused his eyes to be put out, he there kept him under ward till his death. With this William son of Tancred were taken his three sisters, to wit, Alberia, Constance, and Ernadama. When the Emperor Henry was dead, and the young William who had been castrated and whose eyes had been put out was dead also, Philip, duke of Suabia, through the prayers of his wife, which was daughter of the Emperor Manuel of Constantinople, delivered these three daughters of King Tancred from exile and from prison, and let them go free. And Alberia or Aceria had three husbands: the first was Count Walter of Brienne, brother of King John, from whom was born Walteran, count of Joppa, to whom the king of Cyprus gave his daughter in marriage. After Count Walter had been slain by Count Trebaldo [Diephold], the German, Alberia was wedded to Count James of Tricarico, by whom she had Count Simon and the Lady Adalitta; and he being dead, Pope Honorius gave Alberia to wife to Count Tigrimo, count palatine in Tuscany; and for dowry he gave her the region of Lizia and of Mount Scaglioso in the kingdom of Apulia. Constance was the wife of Marchesono [Ziani], doge of Venice. The third sister, who was named Ernadama, had no husband. These were the fortunes of the successors of Robert Guiscard in the kingdom of Sicily and of Apulia, down to Constance, mother of the Emperor Frederick the son of King Henry; and thus it may be seen that Robert Guiscard and his successors ruled over the kingdom of Sicily and of Apulia 120 years. We will now leave the kings of Sicily and of Apulia; and we will relate concerning the wise Countess Matilda. Sec. 21.--_Of the Countess Matilda._ [Sidenote: 1115 A.D.]
