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 6^th ecumenical council was held at Constantinople, to which he sent his legates and those from a Roman council held in 679. Agatho died on the 10^th of January 681.
