According to tradition the earliest Greek inhabitants of kos came from Epidaurus, small city on the Argolid Peninsula, bringing with them the worship of Asklepios, for which the island was afterwards celebrated. Herakles was also worshiped on the island, even more than Asklepios because the city was a member of the Dorian Pentapolis. It was therefore also appropriate for Kos to include Herakles on it's coins. In the period of 166-88 B.C., a complete change toke place in the coinage of both Kos and Rhodos. This change is even more apparent for Kos than Rhodos, since the long time honoured Heraklean types of Dorian origin were now abandoned in favour of types related to Asklepios. His worship had gradually passed that of Herakles, and became now the representative divinity of the island. Kos now issued remarkable tetradrachms of Attic weight with Aphrodite on the obverse and Asklepios on the reverse. Example of the remarkable tetradrachm from Kos The smaller denominations however, continued to be minted of Rhodian weight. These coins were characterized by the restoration of the incuse square on the reverse, similar to that of the Rhodian coins and the Lycian league coins on the mainland. The tetrobol issues show the head of Asklepios on the obverse and a coiled serpent on the reverse. The reverse shows one or two magistrate names and the full name of the island: ΚΩΙΩΝ or an abbreviation of it: ΚΩΙ, ΚΩ or ΚΩN. Islands off Caria, Kos. AR Tetrobol.

On the island a famous Asklepion was located, and it was attended by Hippocrates, who was born on Kos ca. 460BC. He took lessons there from the Thracian Physician Herodikos of Selymbria. The Asklepion was build on a site overlooking the town of Kos. Since the buildings are on a slope, the Asklepion was build in several terraces and connected with impressive, free-standing marble staircases. The three terraces of the Asklepion. The lower terrace rooms were located where the patients were staying during their treatment. An inscription found in the southern part of this terrace mentions doctor Gaius Stertinius Xenophon, the personal physician of Claudius, from Kos. It is also interesting to know that two underground spaces have also been found on this terrace. It is assumed that these special rooms were reserved for patients with venereal diseases and Leprosy. A group of buildings were also dedicated to training and housed the doctor's school. The middle terrace is the oldest part of the sanctuary, which dates back to the 4th century BC. It contained the medicinal baths, fed by a source from Mount Dikeos. Also several temples of the Ionian Order dedicated to Asklepios were located there, as well as a later built temple build in the Corinthian Order. On the third (upper) terrace was a large marble temple in the Doric order, an exact copy of the temple in Epidauros, which was dedicated to Asklepios of Kiparissios Apollo. From the upper terrace, a staircase led further to a sacred pine and cypress forest. The forest, dedicated to Apollo, presumably granted immortality to all women living there and prevented them from having children. Post your coins from Kos and coins showing Asklepios!
