Arkoi in the context of "Patmos"

The Dodecanese (UK: /ˌdoʊdɪkəˈniːz/, US: /doʊˌdɛkəˈniːz/; Greek: Δωδεκάνησα, Dodekánisa [ðoðeˈkanisa], lit. 'twelve islands') are a group of 15 larger and 150 smaller Greek islands in the southeastern Aegean Sea and Eastern Mediterranean, off the coast of Anatolia, of which 26 are inhabited. This island group generally defines the eastern limit of the Sea of Crete. They belong to the wider Southern Sporades island group.

Rhodes has been the area's dominant island since antiquity. Of the others, Kos and Patmos are historically the most important; the remaining 12 are Agathonisi, Astypalaia, Halki, Kalymnos, Karpathos, Kasos, Leipsoi, Leros, Nisyros, Symi, Tilos, and Megisti. Other islands in the chain include Alimia, Arkoi, Farmakonisi, Gyali, Kinaros, Levitha, Marathos, Nimos, Pserimos, Saria, Strongyli and Syrna.

Agathonísi (Greek: Αγαθονήσι) is a small Greek island and municipality located at the northernmost point of the Dodecanese in Greece. It is surrounded by many smaller islands and is home to two villages, both inland; Megalo Chorio ("Big Village"), and Mikro Chorio ("Small Village"). Between them is the small settlement of Agios Georgios (Saint George), which forms the island's only harbor and consists of a few hotels and restaurants. The island is also locally known as Gaidaro ("Donkey"), or by its ancient name Tragea.

The highest point on the island is 209 metres (686 feet) above sea level. This peak is located close to Mikro Chorio. The island covers an area of 13.5 square kilometres (5.2 square miles). It is made almost entirely of subcrystalline stratified limestones, and is covered with thorny macchia.

Leipsoi (Greek: Λειψοί [lipˈsi]; also: Lipsi; Ancient Greek: Λέψια, Lepsia) is an island south of Samos and to the north of Leros in Greece. It is well served with ferries passing between Patmos and Leros and on the main route for ferries from Piraeus. Leipsoi is a small group of islets at the northern part of the Dodecanese near Patmos island and Leros. The larger Leipsi-Arkoi archipelago consists of some 37 islands and islets of which only three are larger than 1 square kilometre (247 acres): Leipsoi (15.95 square kilometres (6.16 sq mi)), Arkoi (6.7 square kilometres (2.59 sq mi), part of Patmos municipality) and Agreloussa (1.32 square kilometres (0.51 sq mi), part of Patmos municipality). Only Leipsoi, Arkoi, and Marathos are inhabited. Leipsoi is a municipality, part of the Kalymnos regional unit, which is part of the South Aegean region. The municipality has an area of 17.350 square kilometres (6.699 sq mi). In ancient times, it contained a town named Lepsia.

Marathos or Marathi is a small Greek Island in the Aegean Sea lying east of Patmos island, southwest of Arkoi island, and northwest of Leipsoi island. It is part of the Dodecanese archipelago. It is a small island with an area of 36 hectares (89 acres) but there are a couple of tavernas and few rooms to let.
