Aquileian Patriarch Ulrich II of Treffen launches an attack on Venetian Grado as he tries to subjugate the competing patriarchal see; he fails miserably and ends up locked in a Venetian prison where he “buys” his freedom by signing a new treaty with Venice and agreeing to a yearly tribute of twelve loaves of bread and twelve pigs that his Church would perpetually bring to the ducal palace of Venice before the Fat Thursday festivities (narrative accounts from later Venetian chronicles).
