National Archaeological Museum, Athens in the context of "Dipylon Amphora"

The Antikythera mechanism (/ˌæntɪkɪˈθɪərə/ AN-tik-ih-THEER-ə, US also /ˌæntaɪkɪˈ-/ AN-ty-kih-) is an ancient Greek hand-powered orrery (model of the Solar System). It is the oldest known example of an analogue computer. It could be used to predict astronomical positions and eclipses decades in advance. It could also be used to track the four-year cycle of athletic games similar to an olympiad, the cycle of the ancient Olympic Games.

The artefact was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera in 1901. In 1902, during a visit to the National Archaeological Museum in Athens, it was noticed by Greek politician Spyridon Stais as containing a gear, prompting the first study of the fragment by his cousin, Valerios Stais, the museum director. The device, housed in the remains of a wooden-framed case of (uncertain) overall size 34 cm × 18 cm × 9 cm (13.4 in × 7.1 in × 3.5 in), was found as one lump, later separated into three main fragments which are now divided into 82 separate fragments after conservation efforts. Four of these fragments contain gears, while inscriptions are found on many others. The largest gear is about 13 cm (5 in) in diameter and originally had 223 teeth. All these fragments of the mechanism are kept at the National Archaeological Museum, along with reconstructions and replicas, to demonstrate how it may have looked and worked.

The sculpture of ancient Greece is the main surviving type of fine ancient Greek art as, with the exception of painted ancient Greek pottery, almost no ancient Greek painting survives. Modern scholarship identifies three major stages in monumental sculpture in bronze and stone: Archaic Greek sculpture (from about 650 to 480 BC), Classical (480–323 BC) and Hellenistic thereafter. At all periods there were great numbers of Greek terracotta figurines and small sculptures in metal and other materials.

The Greeks decided very early on that the human form was the most important subject for artistic endeavour. Since they pictured their gods as having human form, there was little distinction between the sacred and the secular in art—the human body was both secular and sacred. A male nude of Apollo or Heracles shows only slight differences in treatment from a sculpture of that year's Olympic boxing champion. The statue (originally single, but by the Hellenistic period often in groups) was the dominant form, although reliefs, often so "high" that they were almost free-standing, were also important.

A shield is a piece of personal armour held in the hand, which may or may not be strapped to the wrist or forearm. Shields are used to intercept specific attacks, whether from close-ranged weaponry like spears or long ranged projectiles such as arrows. They function as means of active blocks, as well as to provide passive protection by closing one or more lines of engagement during combat.

Shields vary greatly in size and shape, ranging from large panels that protect the user's whole body to small models (such as the buckler) that were intended for hand-to-hand-combat use. Shields also vary a great deal in thickness; whereas some shields were made of relatively deep, absorbent, wooden planking to protect soldiers from the impact of spears and crossbow bolts, others were thinner and lighter and designed mainly for deflecting blade strikes (like the roromaraugi or qauata). Finally, shields vary greatly in shape, ranging in roundness to angularity, proportional length and width, symmetry and edge pattern; different shapes provide more optimal protection for infantry or cavalry, enhance portability, provide secondary uses such as ship protection or as a weapon and so on.

Helmets using ivory from boars' tusks were known in the Mycenaean world from the 17th century BC (Shaft Graves, Mycenae) to the 10th century BC (Elateia, Central Greece). The helmet was made through the use of slivers of boar tusks which were attached to a leather base, padded with felt, in rows. A description of a boar's tusk helmet appears in book ten of Homer's Iliad, as Odysseus is armed for a night raid to be conducted against the Trojans.

Fragments of ivory which might have come from helmets of this kind have been discovered on Mycenaean sites (at Dendra, for instance, fragments were found alongside the bronze panoply excavated in 1960) and an ivory plaque, also from a Mycenaean site, represents a helmet of this kind. Although they would not provide protection as good as that of a metal helmet, they may have been worn by some leaders as a status symbol, or a means of identification.

Thermos (/ˈθɜːrmɒs/; also known as Thermon /ˈθɜːrmən/, Thermum; Ancient Greek: Θέρμος or Thermika) was an ancient Greek sanctuary, which served as the regular meeting place of the Aetolian League. Its focal point was the temple of Apollo Thermios of about 630 to 610 BC, "one of the earliest developed Doric temples known and a monument of primary importance for our knowledge of the history of Greek architecture". The most famous survivals are the Archaic terracotta metopes decorated with painted scenes from mythology, which are among the earliest examples of this art form in Greece. What is left of these, and other finds from the site, are now in the museum at Thermos, with a selection of the best pieces in National Archaeological Museum, Athens.

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.

Milos or Melos (/ˈmiːlɒs, -loʊs/; Modern Greek: Μήλος, romanized: Mílos, IPA: [ˈmilos]; Ancient Greek: Μῆλος, romanized: Mêlos) is a volcanic Greek island in the Aegean Sea, just north of the Sea of Crete. It is the southwestern-most island of the Cyclades group.

The Venus de Milo (now in the Louvre), the Poseidon of Melos (now in the NAMA) and the Asclepius of Milos (now in the British Museum) were all found on the island, as was an archaic Apollo now in Athens. Milos is a popular tourist destination during the summer. The municipality of Milos also includes the uninhabited offshore islands of Antimilos and Akradies. The combined land area is 160.147 square kilometres (61.833 sq mi) and at the 2021 census the population was 5,193 inhabitants.

Klinai (Greek; sg.: κλίνη klinē), known in Latin as lectus triclinaris, were a type of ancient furniture used by the ancient Greeks in their symposia and by the ancient Romans in their somewhat different convivia.

In the later part of the Hellenistic period, an arrangement of three klinai positioned in a 'U' shape developed, which together formed the triclinium. Each kline of a triclinium offered room for three diners. The seating arrangement of the reclining dinner guests was given a strict significance.
