Answer the following question: Information:  - The Dionysian Mysteries were a ritual of ancient Greece and Rome which used intoxicants and other trance-inducing techniques (like dance and music) to remove inhibitions and social constraints, liberating the individual to return to a natural state. It also provided some liberation for those marginalized by Greek society: women, slaves and foreigners. In their final phase the Mysteries shifted their emphasis from a chthonic, underworld orientation to a transcendental, mystical one, with Dionysus changing his nature accordingly. By its nature as a mystery religion reserved for the initiated, many aspects of the Dionysian cult remain unknown and were lost with the decline of Greco-Roman polytheism; modern knowledge is derived from descriptions, imagery and cross-cultural studies.  - Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek.  - Plato ( also Plato Comicus ; Ancient Greek :   ) was an Athenian comic poet and contemporary of Aristophanes . None of his plays survive intact , but the titles of thirty of them are known , including a Hyperbolus ( c. 420 - 416 BC ) , Victories ( after 421 ) , Cleophon ( in 405 ) , and Phaon ( probably in 391 ) . The titles suggest that his themes were often political . In 410 BC , one of his plays took first prize at the City Dionysia . Phaon included a scene ( quoted in the Deipnosophistae of Athenaeus ) in which a character sits down to study a poem about gastronomy ( in fact mostly about aphrodisiacs ) and reads some of it aloud . The poem is in hexameters , and therefore sounds like a lampoon of the work of Archestratus , although the speaker calls it `` a book by Philoxenus '' , meaning either the poet Philoxenus of Cythera , the glutton Philoxenus of Leucas , or both indiscriminately .  - In Ancient Greece, a deme or demos was a suburb of Athens or a subdivision of Attica, the region of Greece surrounding Athens. Demes as simple subdivisions of land in the countryside seem to have existed in the 6th century BC and earlier, but did not acquire particular significance until the reforms of Cleisthenes in 508 BC. In those reforms, enrollment in the citizen-lists of a deme became the requirement for citizenship; prior to that time, citizenship had been based on membership in a phratry, or family group. At this same time, demes were established in the city of Athens itself, where they had not previously existed; in all, at the end of Cleisthenes' reforms, Attica was divided into 139 demes to which one should add Berenikidai, established in 224/223 BC, Apollonieis (201/200 BC) and Antinoeis (126/127). The establishment of demes as the fundamental units of the state weakened the gene, or aristocratic family groups, that had dominated the phratries.  - Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th-9th centuries BC to the end of antiquity (AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the period of Archaic Greece and colonization of the Mediterranean Basin. This was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. The Hellenistic period came to an end with the conquests and annexations of the eastern Mediterranean world by the Roman Republic, which established the Roman province of Macedonia in Roman Greece, and later the province of Achaea during the Roman Empire.  - Mycenaean Greek is the most ancient attested form of the Greek language, on the Greek mainland, Crete and Cyprus in Mycenaean Greece (16th to 12th centuries BCE), before the hypothesised Dorian invasion, often cited as the "terminus post quem" for the coming of the Greek language to Greece. The language is preserved in inscriptions in Linear B, a script first attested on Crete before the 14th century. Most inscriptions are on clay tablets found in Knossos, in central Crete, as well as in Pylos, in the southwest of the Peloponnese. Other tablets have been found at Mycenae itself, Tiryns and Thebes and at Chania, in Western Crete. The language is named after Mycenae, one of the major centres of Mycenaean Greece.  - The Hellenistic period covers the period of ancient Greek (Hellenic) history and Mediterranean history between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire as signified by the Battle of Actium in 31 BC and the subsequent conquest of Ptolemaic Egypt the following year. At this time, Greek cultural influence and power was at its peak in Europe, Africa and Asia, experiencing prosperity and progress in the arts, exploration, literature, theatre, architecture, music, mathematics, philosophy, and science. It is often considered a period of transition, sometimes even of decadence or degeneration, compared to the enlightenment of the Greek Classical era. The Hellenistic period saw the rise of New Comedy, Alexandrian poetry, the Septuagint and the philosophies of Stoicism and Epicureanism. Greek Science was advanced by the works of the mathematician Euclid and the polymath Archimedes. The religious sphere expanded to include new gods such as the Greco-Egyptian Serapis, eastern deities such as Attis and Cybele and the Greek adoption of Buddhism.  - The Dionysia was a large festival in ancient Athens in honor of the god Dionysus, the central events of which were the theatrical performances of dramatic tragedies and, from 487 BC, comedies. It was the second-most important festival after the Panathenaia. The Dionysia actually consisted of two related festivals, the Rural Dionysia and the City Dionysia, which took place in different parts of the year. They were also an essential part of the Dionysian Mysteries.  - The Peloponnesian War (431404 BC) was an ancient Greek war fought by Athens and its empire against the Peloponnesian League led by Sparta. Historians have traditionally divided the war into three phases. In the first phase, the Archidamian War, Sparta launched repeated invasions of Attica, while Athens took advantage of its naval supremacy to raid the coast of the Peloponnese and attempt to suppress signs of unrest in its empire. This period of the war was concluded in 421 BC, with the signing of the Peace of Nicias. That treaty, however, was soon undermined by renewed fighting in the Peloponnese. In 415 BC, Athens dispatched a massive expeditionary force to attack Syracuse in Sicily; the attack failed disastrously, with the destruction of the entire force, in 413 BC. This ushered in the final phase of the war, generally referred to either as the Decelean War, or the Ionian War. In this phase, Sparta, now receiving support from Persia, supported rebellions in Athens' subject states in the Aegean Sea and Ionia, undermining Athens' empire, and, eventually, depriving the city of naval supremacy. The destruction of Athens' fleet at Aegospotami effectively ended the war, and Athens surrendered in the following year. Corinth and Thebes demanded that Athens should be destroyed and all its citizens should be enslaved, but Sparta refused.  - Aristophanes (or  ; c. 446  c. 386 BC), son of Philippus, of the deme Kydathenaion, was a comic playwright of ancient Athens. Eleven of his forty plays survive virtually complete. These, together with fragments of some of his other plays, provide the only real examples of a genre of comic drama known as Old Comedy, and are used to define it.  - Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.  Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki.  - Hyperbolus ("Hyperbolos") was an Athenian politician active during the first half of the Peloponnesian war, coming to particular prominence after the death of Cleon.  - Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study.  - Old Comedy ("archaia") is the first period of the ancient Greek comedy, according to the canonical division by the Alexandrian grammarians. The most important Old Comic playwright is Aristophanes  whose works, with their daring political commentary and abundance of sexual innuendo, effectively define the genre today. Aristophanes satirized and lampooned the most prominent personalities and institutions of his time, as can be seen, for example, in his scurrilous portrayal of Socrates in "The Clouds", and in his racy anti-war farce "Lysistrata". Aristophanes was only one of a large number of comic poets, however, working in Athens in the late 5th century BC; his biggest rivals were Hermippus and Eupolis.  - Dionysus ("Dionysos") is the god of the grape harvest, winemaking and wine, of ritual madness, fertility, theatre and religious ecstasy in ancient Greek religion and myth. Wine played an important role in Greek culture, and the cult of Dionysus was the main religious focus for its unrestrained consumption. He may have been worshipped as early as c. 15001100 BC by Mycenean Greeks; traces of Dionysian-type cult have also been found in ancient Minoan Crete. His origins are uncertain, and his cults took many forms; some are described by ancient sources as Thracian, others as Greek. In some cults, he arrives from the east, as an Asiatic foreigner; in others, from Ethiopia in the South. He is a god of epiphany, "the god that comes", and his "foreignness" as an arriving outsider-god may be inherent and essential to his cults. He is a major, popular figure of Greek mythology and religion, becoming increasingly important over time, and included in some lists of the twelve Olympians, as the last of their number, and the only god born from a mortal mother. His festivals were the driving force behind the development of Greek theatre.
