Patmos is one of the small islands of the Dodecanese complex off the western coast of Asia Minor in the Aegean Sea not far from Miletus on the mainland. The 17 square-mile island is situated opposite of Miletus, where Paul stopped on the return trip of the third missionary journey. Miletus is a little south of Ephesus, one of the seven churches of Revelation. The main building on the island is the monastery of Saint John operated by the Greek Orthodox Church.
Prochorus is not well known to most Bible readers. In Acts 6:5, he is one of the seven Hellenist leaders chosen to assist in the daily distribution of food for the Hellenist widows. Luke tells us no more, so legend fills in the gap for inquiring minds. We have multiple traditions in the Catholic Church about Prochorus. One of these legends connects him to John on Patmos as the scribe of John. Supposedly, Prochorus took John’s diction as John had his vision in a cave on Patmos. This legend, however, directly contradicts what John explicitly told us about the time and circumstance of the writing of Revelation.
