Wikipedia extract

Leo's Tome was a rescript sent by Pope Leo I to Archbishop Flavian of Constantinople, explaining the position of the see of Rome in matters of Christology. The letter was written in response to a letter from Flavian, who had excommunicated Eutyches, who also wrote to the pope to appeal the excommunication.
