Rizzardo dalle Carceri
Rizzardo dalle Carceri (died 1220) was a Lombard hexarch of Negroponte. A son of Redondello dalle Carceri and nephew of Ravano, he received a share of the northern triarchy of Oreos in the Venetian bailo's partition, ruling it alongside his brother Marino I.
He died in 1220, and his daughter Carintana inherited his sixth. When she died childless in 1255, the dispute over her inheritance grew into the War of the Euboeote Succession.
