1911 Encyclopædia Britannica/Agatho
AGATHO, pope from 678 to 681, was born in Sicily. He is noteworthy as the pope who ordered St Wilfrid to be restored to his bishopric at York in 679, and as the first to cease payment of the tribute hitherto paid on election to the emperor at Constantinople. It was during his pontificate that the 6th oecumenical council was held at Constantinople, to which he sent his legates and those from a Roman council held in 679. Agatho died on the 10th of January 681.
