According to the historian Marino Sanudo, Villehardouin called upon Guglielmo and Narzotto to present themselves to him. Constrained by their feudal oaths of fealty, they did so and were imprisoned by the Achaean prince. The triarchs' wives, accompanied by many knights and other kinsmen, then went to the Venetian "bailo", and beseeched his aid. "Moved alike by policy and sympathy", as the historian William Miller states, Paolo Gradenigo assented. Sanudo portrays this as the origin of the Venetian assistance to the triarchs, and claims that the triarchs remained imprisoned until after Villehardouin himself was captured at Pelagonia in 1259, but this may in fact reflect a brief imprisonment, since the two triarchs were clearly at liberty in June 1256 and January 1257.
