The Aegean Sea lies between the Greek mainland and Anatolia, and its islands and coasts held much of Greek religious life. Delos was treated as the birthplace of Apollo and Artemis and was kept ritually pure, with births and burials forbidden on the island; Samothrace held the mystery cult of the Great Gods; and the great sanctuaries of the Ionian coast faced the water rather than the interior. The Acts of the Apostles has Paul crossing it repeatedly, and Patmos, where the book of Revelation is set, lies in its eastern waters.

Facts

Origins

Origin Region

The eastern Mediterranean between the Greek mainland and Anatolia, an archipelago of several hundred islands in the Cyclades, Dodecanese, Sporades and northern groups, set close enough together that crossings could be made largely within sight of land. 2

Region

Greece and Turkey. Delos is uninhabited and has been on the UNESCO World Heritage List since 1990, its whole surface treated as an archaeological site, while Patmos and Mount Athos remain in continuous religious use. 3

Significance

Sacred Role

The setting of Greek purity practice at its sharpest. Athens purified Delos in 426 BCE, removing every grave from the island, and thereafter no one was permitted to be born or to die there, so that the birthplace of Apollo and Artemis should carry none of the pollution of mortality; the dying and those about to give birth were carried across to neighbouring Rheneia. 1

Attributions

Associated Religion

Ancient Greek religion above all, whose island and coastal sanctuaries at Delos, Samothrace, Ephesus and Didyma faced this water rather than the interior. The same sea later carried the earliest Christian mission into Greece, and the Orthodox monastic republic of Mount Athos occupies a peninsula reaching into its northern waters. 2

An Island Kept Pure and an Island That Kept Secrets

The Aegean is a sea full of islands, and Greek religion used two of them in opposite ways.

Delos was held to be Apollo's birthplace, the ground where Leto finally found refuge and bore him and Artemis, and the island was treated as sacred accordingly. Athens conducted purifications of it more than once, and the rule that resulted was extreme: no one was to be born on the island and no one to die there, so the sick and the pregnant were removed to a neighbouring islet. Graves were dug up and moved. The island became a major sanctuary and, later, a commercial free port, so the sacred and the mercantile occupied the same small rock.

Samothrace, in the northern Aegean, held the mysteries of the Great Gods, and it kept them. Initiates were admitted at any time, in two grades, without restriction by status or origin, which was unusual, and they did not disclose what happened; even the names of the gods concerned are given only obliquely in the surviving sources. Sailors sought initiation for protection at sea, which suited a sanctuary on a mountainous island in exposed water.

The great Ionian sanctuaries on the eastern shore, Didyma, Ephesus, Samos, faced the water rather than the interior, and were reached by sea as a matter of course. The Aegean was not an obstacle between Greek communities; it was the road between them.

The Sea Paul Kept Crossing

The Aegean is also the water on which the earliest Christian expansion outside the Levant took place, and the Acts of the Apostles reads in places like a shipping itinerary.

Paul crosses from Asia Minor into Macedonia and works down through Philippi, Thessalonica and Beroea to Athens and Corinth; later journeys take him to Ephesus for an extended stay, back across to Troas, and eventually toward Rome. The congregations founded on those coasts are the recipients of most of the surviving letters, and the arguments in them, about food offered to idols, about the resurrection, about whether gentile converts must keep the law, are arguments taking place in port cities where several religions were already competing for the same audiences.

Ephesus is the clearest case. It held the temple of Artemis, one of the largest religious structures in the Greek world and a major economic institution, and Acts records a riot provoked by silversmiths who made shrines of the goddess and saw their trade threatened. Whatever the details, the account describes a real economy of devotion that a new movement disrupted.

Patmos, a small island off the Ionian coast, is where the book of Revelation places its author, in exile. Its monastery of Saint John, founded in 1088, and the cave identified as the site of the vision have drawn pilgrims for a thousand years, and the island remains an Orthodox destination.
