Thermos   also known as Thermon  ( Greek: Θέρμος) was an ancient Greek sanctuary, which served as the regular meeting place of the Aetolian League.[1] Its focal point was the temple of Apollo Thermios, famous for the archaic terracotta metopes decorated with painted scenes from mythology, which are among the earliest examples of this art form in Greece.

Thermos was already an important regional centre in the prehistoric period: a long apsidal building (with one rounded end: “Megaron A”), elliptical and square houses with finds of pottery in the Middle Helladic tradition together with imports of high quality Mycenaean pottery can all be dated to the Late Helladic IIA period c. 1500 BC. This settlement continued to flourish throughout the Mycenaean period, even after the destruction of the Mycenaean palaces (LH IIIC, 1200-1100 BC) when a fine krater (large bowl) decorated with warriors in the same style as the well-known Warrior Vase found by Heinrich Schliemann at Mycenae was brought to the site.


A large rectangular building (Megaron B) which underlies the Temple of Apollo was long thought to demonstrate the hypothetical development of the Archaic Greek temple form from the Mycenaean palace with the addition of a peristyle (or surrounding colonnade). Recent excavations, however, conducted by Professor I. Papapostolou for the Archaeological Society of Athens (Archaiologike Etairia Athenon) have demonstrated that a) the building is likely to have been constructed after the end of the Mycenaean period c. 1000-900 BC; b) that the curious horseshoe shaped setting of stone slabs which appeared to surround the Megaron was only put in place after the Megaron had gone out of use and c) that the burnt stratum with the typical offerings of the later Geometric period (800-700 BC), attested at many Greek sanctuary sites such as Olympia and Delphi, intervenes between the slabs and the foundations of the Archaic temple which carried the painted metopes. Thus, although the site of the temple was obviously of special importance from at least the end of the Mycenaean period, there is no demonstrable architectural continuity. Thermos was not a city in the sense of a built-up urban centre like Athens, Argos or Corinth and until a late date the Aetolian League was a loose association with a tribal basis rather than a group of city-states. It is not known whether the sanctuary had a formal boundary before the Hellenistic period when substantial fortification walls with gates and towers were built on three sides of the enclosure. At the same time, three long stoas (verandah-like halls) were built within the precinct and the spring just to the south of the temple (perhaps the original reason for the location of the site) was enclosed to form a fine stone-lined pool.


The Aetolians at this period embellished the sanctuary with astonishing numbers of bronze dedicatory statues but today only a few fragments (fingers and toes or horses’ hooves) as well as the marble bases on which they stood, survive to illustrate this wealth. Unfortunate political alliances led to the sack of the site first by the King Philip V of Macedon during the Social War of 220-217 BC and then by the Romans in 189 BC which effectively ended its existence.[2]


Modern village

The ancient name is preserved in the nearby contemporary Greek village of Thermo.

Cosmas of Aetolia, sometimes Kosmas of Aetolia or Cosmas/Kosmas the Aetolian or Patrokosmas “Father Cosmas” (Greek: Κοσμάς Αιτωλός, Kosmas Etolos; born between 1700 and 1714 – died 1779), was a monk in the Greek Orthodox Church.

Saint Cosmas, the “Equal to the Apostles,” was officially proclaimed a Saint by the Orthodox Church of Constantinople on 20 April 1961. His feast day is celebrated on 24 August, the date of his martyrdom.


Cosmas was born in the Greek village Mega Dendron near the town of Thermo in the region of Aetolia.[1] He studied Greek and theology before becoming a monk after a trip to Mount Athos where he also attended the local Theological Academy.

After two years Cosmas left Athos. He studied rhetoric in Constantinople for a time. In 1760 he was authorized by Patriarch Serapheim II (who had marked anti-Ottoman tendencies) to begin missionary tours in the villages of Thrace – later extended to what would form the areas of both West Greece and Northern Greece. The Patriarch had been reportedly worried at the increasing rate of Christians converting to Islam in these areas.

Over sixteen years, Cosmas established many church schools in villages and towns. He called upon Christians to establish schools and learn Biblical Koine Greek, that they might understand the Scriptures better and generally educate themselves.

After the Orlov Revolt of 1770 in the Peloponnese (which was provoked by the Orlov brothers with the support of Catherine II of the Russian Empire), Cosmas started to preach in what is now Southern Albania,[1] then under the rule of Ahmet Kurt Pasha, governor of the Pashalik of Berat.

His preachings had aroused the opposition of the rich and powerful and others who felt their position threatened, such as the kotsampasides (Greek “village elders” whose power and influence was bound up with the Ottoman power).

Cosmas was also viewed with suspicion by officials of the Venetian Republic, then in its final stages of decline, which ruled parts of the territory where he was active. For example, in 1779 he is said to have visited the Venetian-ruled town of Preveza and founded there a Greek school, which would be the only school of the city during the 18th century – an act which the Venetian authorities might have considered as undermining their rule. The Venetians’ suspicions are attested in spy reports about Cosmas preserved in the Venetian archives. In contrast, Cosmas had considerable support from other Christians and even from some Turks.

In his sermons Cosmas often refers negatively to the Jews. Nevertheless, in one of his preachings he stated specifically that: “Those who wrong Christians, Jews or Turks would be paid back for the injustice they committed”.


One effect of his preaching was to transfer the holding of the weekly bazaar (fair) from Sunday to Saturday, which brought economic losses to Jews – barred by their religion from engaging in business on Sabbath. Some researchers believe that for that reason, Jews in Epirus were involved in his conviction by the Ottoman authorities.

Accused of being a Russian agent, he was seized by Ottoman authorities. On 24 August 1779, he was executed at Kolkondas, Fier District, near the mouth of the Seman river (in present-day Albania). There were no formal charges brought against him, nor was he put on trial before being executed – leading to various theories, persisting up to the present, about who might have wanted him dead.

In 1813 Ali Pasha, the de facto independent Muslim Albanian ruler of Ottoman Epirus, southern Albanian and Macedonia, and an enemy of the Sultan – managed to have a church built near the site of Cosmas’ execution, in which the remains of Cosmas were placed. Ali Pasha went as far as having a date of celebration set in Cosmas’ honor. Some other Muslims disliked Ali Pasha’s “giving too much honor to a giaouri”, to which the Pasha reportedly replied: “Bring me a Muslim like him, I would kiss his legs.”. From different French and English writers of his time he was known as a friend and a sustain for Father Cosmas.

Later, in 1984 the remains were transferred from the St. Cosmas’ Monastery in Kolkondas, where he was killed, to the Archaeological Museum of Fier. Other relics of the saint are kept in the Metropolitan Cathedral of Athens. Saint Kosmas’ pilgrimage is also revered by some Greek nationalist circles.[6][5] The later being associated with the Northern Epirus issue and support the annexation of this region to Greece.[7][5][6] Although a hellenizer, Saint Cosmas of Aetolia is still highly regarded by Orthodox Albanians for the message that he gave.

There are numerous popular religious texts attributed to St. Cosmas. Best known are the five “Didaches” and the “Prophecies”. There survive, however, no original manuscript of these texts written personally by St. Cosmas, and none can be dated with certainty. His writings are known only from second or third-hand transcriptions.[8] It is believed that these texts are based on Cosmas’ preachings but were written and copied mostly after his death.
