The small island of Patmos is about 7.5 miles (12 km) long from north to south and at its widest is 6 miles (10 km) from east to west. It is the northernmost island of the Dodecanese. With an area of 13 square miles (35 sq. km) and a circumference of 25 miles (37 km), the volcanic island presents a largely rocky and treeless landscape.
The book of Revelation explicitly states that it was written while John was on the island of Patmos. This is the only book in the New Testament where the place of writing is given. According to a tradition preserved by Irenaeus, Eusebius, and Jerome, John was exiled in AD 95 during the reign of Emperor Domitian. His exile ended upon the accession of Nerva in 96.
Holy Cave of Apocalypse
Rev 1:9 (ESV) “I, John, your brother and partner in the tribulation and the kingdom and the patient endurance that are in Jesus, was on the island called Patmos on account of the word of God and the testimony of Jesus.”
According to Pliny and Tacitus, the Romans often sent their prisoners to islands. Tacitus mentions three islands in the Sporades by name: Donusa, Gyarus, and Amorgus. That Patmos was not listed indicates that it was not a primary place for imprisonment at this time. It is not clear if John was imprisoned on Patmos or banished here to live.
Monastery of St. John
The most imposing building on the island is the Monastery of St. John the Theologian. Constructed by Christodoulos in 1088, the monastery is located in the town of Chora overlooking the harbor. With walls 50 feet (15 m) high, it was built like a fortress because of the threat from pirates. The monastery was built on top of the remains of a 4th century AD church and an earlier temple of Artemis. An inscription that mentions the temple of Artemis is displayed in the monastery’s museum.
A tradition says that John received the vision of Revelation from heaven verbatim and dictated it to his assistant Procorus, who wrote it down. Procorus is mentioned in Acts 6:5 as one of the seven original deacons. Many other traditions on the island are associated with miraculous works of John and are found in the Acts of John by Prochorus, a pseudipigraphal work that was written in the 5th century and attributed to John’s scribe (cf. Acts 6:5).
