Robert Guiscard and his army plunder and burn Rome as punishment for the population's rebellion against Pope Gregory VII. and because one of Robert's men had been injured by them.
Ruobertus Wiscardus dux Nordmannorum in servicium sancti Petri post Kal. Maii Romam armata manu invasit, fugatoque Heinrico totam urbem Gregorio papae rebellem penitus expoliavit, et maiorem eius partem igni consumpsit, eo quod Romani quendam eius militem vulneraverint.
