Kos (Cos) is a Greek island in the south-east Aegean (ancient) Sporades group which prospered in antiquity due to its location on trade routes between Egypt, Syria, Cyprus, and Anatolia. Settled from the Bronze Age, the island was controlled by a long list of powers over the centuries. One of Kos’ most famous sons was the celebrated physician Hippocrates, who created a school of medicine on the island in the 5th century BCE. Kos particularly flourished both politically and culturally in the 4th century BCE, after which it became a free city as part of the Roman Empire.  

Bronze Age Kos

In Greek mythology, Eurypylos is mentioned as the king of Kos and contributor to the Greek army involved in the Trojan War of Homer’s Iliad. In the same book we are told that Hera removed Hercules to the island when he was trying to return home after his sacking of Troy. The first archaeological evidence of settlements on Kos confirms an even earlier Bronze Age presence (3rd millennium BCE) with burial jars and metal objects such as daggers being excavated. Middle Bronze Age finds also demonstrate an influence from Minoan Crete and contact with Egypt.

The first large settlements, such as Serayia (Seraglio), have fortification walls and tholos tombs dating to the Mycenaean period (1600-1200 BCE). The island was, no doubt, selected as a useful stopping point on the ancient Mediterranean trade routes between the Levant, Egypt, and Anatolia. Kos was also one of the most fertile Aegean islands. Kos-made pottery was traded with other islands and has been discovered at Trianda and Akrotiri on Thera. Following the collapse of the Mycenaean civilization in the late Bronze Age, the island was next occupied by Doric settlers from mainland Greece, probably Epidaurus. The Serayia cemetery, in use from c. 1050 BCE, dates to this period. It was last used c. 750 BCE, indicating a new cultural influence had arrived.

The great physician Hippocrates was born on Kos where he founded a school of medicine which became famed throughout the Greek world.

Archaic & Classical Kos

From the Archaic period the island came under control of various powers – first Persia, then Halicarnassos, and finally Athens. The most important cities on the island were Astypalaea, Cos Meropis, and Halasarna. In the 5th century BCE, the great physician Hippocrates was born on the island where he founded a school of medicine which became famed throughout the Greek world. From this period, Kos also became a noted exporter of wine and minted its own coinage, perhaps the most famous example of which are the silver tridrachmas which depict a discus thrower (discobolus). In the battle of Salamis between Greek and Persian forces, Kos supplied several ships to the Persian cause, in an island fleet commanded by Artemisia I of Caria. According to Herodotus, the tyrant Kadmos gave the people of the island control of government c. 480 BCE.

Kos subsequently came under the control of Athens and became a tribute-paying member of the Delian League. This offered no particular protection to the island as Kos was sacked by the Spartan general Astyochus in 412 BCE after he took advantage of the disorder caused by a recent and devastating earthquake. According to Thucydides, the Athenian general Themistocles responded by building fortifications on the island in 411 BCE. In 366 BCE all the cities of Kos joined together to form a single political entity. A new city was, consequently, founded on the north-east coast, then fortified, and a harbor created. Mausolus, ruler of Caria, invaded the island in the 350s BCE. In 332 BCE Amphoterus, admiral of Alexander the Great, took possession of the island.

Hellenistic & Roman Kos

Following the Successor Wars after Alexander’s death, Kos regained its independence, established a democratic government and constitution, and became an ally of the Ptolemy dynasty based at Alexandria. Kos exported wine, olive oil, and silk to cities across the Aegean and the Black Sea. Its long-lasting trade and cultural ties with Egypt are illustrated by the fact that Ptolemy II was born on the island and Cleopatra II sent her treasury to Kos c. 102 BCE. A period of cultural activity expressed itself in such figures as the influential Kos poet and scholar Philitas (born c. 340 BCE) and his contemporary the poet Herodas. In 242 BCE the island’s games held in honour of Asclepius were given Panhellenic status, like those at other sacred sites such as Delphi and Olympia. Records describe athletes coming from over 50 different cities to participate, and those were just the winner lists.  

Odeion of Kos

When Rome began to expand its empire from the 2nd century BCE, Kos was made a free city (civitas libera). With the fall of the Roman Republic Kos became a part of the province of Asia. Emperor Claudius granted Kos immunitas (immunity from tax or imperial decree) and the island was one again made a free city in the 1st century CE. In late antiquity the island had merely tributary status again.  

The Asclepeion

The island today has substantial archaeological remains from all the periods of its history. These include the agora and gymnasium from the Classical periods, and from Hellenistic times, a temple and altar of Dionysos. The Roman period of Kos is represented by baths, a gymnasium, houses, villas – many with their surviving mosaics -, and an early Christian basilica. By far the most significant remains are from the large Asclepeion complex for which the island was most famous in antiquity.

The Asclepeion is situated four kilometres outside the city and dates from the 4th to 2nd century BCE. It was built on an older site sacred to Apollo Cyparissius (referring to the cypress groves in the area), who was, of course, the father of Asclepius, the Greek god of medicine. Initially, the site had only a modest altar but it developed over the years, next with a small Ionic temple built and dedicated to Asclepius, and then, under the auspices of king Eumenes II of Pergamon in the 2nd century BCE, a large Doric temple was built to Asclepius which copied the design of his temple at Epidaurus.

The Hellenistic Gymnasium, Kos

The complex eventually spread over three distinct but connected terraces to better perform its function as a place where visitors from across the Aegean could seek health remedies. Facilities included latrines and baths (1st century CE), temples, a library, fountains, and stoas (open colonnaded buildings) as well as features common to sacred areas such as monumental gates (propylaea), exedra (a curved seating area), and rooms for patients and priests. In the 2nd century CE, the Romans built a large temple dedicated to Apollo whose reconstructed columns have been re-stood today. In the 3rd century CE another thermal baths was added to the site, which continued to function into the 5th century CE. In the 6th century CE a Christian church was built in place of the pagan temple, and in medieval times the Knights of St. John reused many blocks of masonry for their castle. The site was rediscovered and excavated from the early 20th century CE, first by a German and then an Italian team of archaeologists.
