Pope Leo II ( – 28 June 683) was the bishop of Rome from 17 August 682 to his death. He is one of the popes of the Byzantine Papacy. Described by a contemporary biographer as both just and learned, he is commemorated as a saint in the Roman Martyrology on 28 June (3 July, pre-1970 calendar). Early career Leo was a Sicilian by birth, the son of a man named Paul. He may have ended up being among the many Sicilian clergymen in Rome due to the attacks of the Caliphate on Sicily in the mid-7th century. Leo was known as an eloquent preacher who was interested in music, and noted for his charity to the poor. Papacy Pope Agatho died on 10 January 681, and although Leo was elected within days, he was not consecrated until 17 August 682. The reason may have been due to Agatho's negotiations with Emperor Constantine IV regarding imperial control of papal elections. Constantine IV had already promised Agatho to abolish or reduce the tax that the Popes had been paying to the imperial treasury at the time of their consecration, an imperial policy that had been in force for about a century. Leo's short-lived pontificate did not allow him to accomplish much. Notably, he confirmed the acts of the Sixth Ecumenical Council (680–681) against Monothelitism. After Leo had notified the emperor that the decrees of the council had been confirmed, he made them known to the people of the West. In letters written to the Visigothic king, bishops, and nobles, he explained what the council had effected, and he called upon the bishops to subscribe to its decrees. During this council, Pope Honorius I was anathematized for tolerating Monothelism. Leo took great pains to make it clear that in condemning Honorius, he did so not because Honorius taught heresy, but because he was not active enough in opposing it. In accordance with the papal mandate, a synod was held at Toledo (684) in which the Third Council of Constantinople was accepted. Leo put an end to the attempts of Archbishops of Ravenna to break from the control of the Bishop of Rome, but also abolished the tax it had been customary for them to pay when they received the pallium. In apparent response to Lombard raids, Leo transferred the relics of some martyrs from the catacombs to churches inside the city walls.
