He was born in Rome in 1086 to wealthy and pious parents. When the Roman Church broke away from the Orthodox around that time, those who continued to uphold Orthodoxy, Antony among them, were persecuted. Antony gave away his worldly possessions and fled to a small rocky island in the sea, where he spent fourteen months in asceticism. During this time, the island miraculously floated like a ship to Novgorod. There, Archbishop Nikita received the young monk and helped him to build a church to the holy Theotokos, which in time became a monastery. St Anthony served there as abbot for many years, reposing in peace in 1148.
