Hades in the context of "Demeter"

Poseidon (/pəˈsaɪdən, pɒ-, poʊ-/; Ancient Greek: Ποσειδῶν, romanised: Poseidôn) is one of the twelve Olympians in ancient Greek religion and mythology, presiding over the sea, storms, earthquakes and horses. He was the protector of seafarers and the guardian of many Hellenic cities and colonies. In pre-Olympian Bronze Age Greece, Poseidon was venerated as a chief deity at Pylos and Thebes, with the cult title "earth shaker"; in the myths of isolated Arcadia, he is related to Demeter and Persephone and was venerated as a horse, and as a god of the waters. Poseidon maintained both associations among most Greeks: he was regarded as the tamer or father of horses, who, with a strike of his trident, created springs (the terms for horses and springs are related in the Greek language). His Roman equivalent is Neptune.

Homer and Hesiod suggest that Poseidon became lord of the sea when, following the overthrow of his father Cronus, the world was divided by lot among Cronus' three sons; Zeus was given the sky, Hades the underworld, and Poseidon the sea, with the Earth and Mount Olympus belonging to all three. In Plato's Timaeus and Critias, the legendary island of Atlantis was Poseidon's domain. In Homer's Iliad, Poseidon supports the Greeks against the Trojans during the Trojan War. In the Odyssey, during the sea-voyage from Troy back home to Ithaca, the Greek hero Odysseus provokes Poseidon's fury by blinding his son, the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, causing the complete loss of his ship and numerous of his companions, and delaying his return by ten years.

Early Greek cosmology refers to beliefs about the origins, development, and structure of the universe in Ancient Greece that existed before the development of Ancient Greek astronomy. The basic elements of this early cosmology included a flat earth, heaven, a cosmic ocean, the afterworld (Hades), and the netherworld (Tartarus). The first three were represented by the gods Gaia, Uranus, and Oceanus (or sometimes Pontus). Ancient Greek cosmology was related to ancient Near Eastern cosmology, and was ultimately replaced by a more systematic and demythologized approach found in ancient Greek astronomy. Its main sources are the poetry of Homer (the Iliad and the Odyssey), Hesiod (the Theogony and the Works and Days), and surviving fragments from Mimnermus.

Beginning in the 5th century BC, elements of the traditional Greek cosmos began to be modified and challenged. One of the earliest of these challenges came from the emergence of the view that the cosmos as a whole was spherical (advocated by Xenophanes, Parmenides, Empedocles, and others). The rotation of the spherical cosmos was said to explain the visible rotation of the stars (an idea called "vortex"). Soon, a spherical model of the earth itself was proposed, which gradually gained acceptance, although the flat earth view never entirely disappeared during either classical antiquity or late antiquity, continuing to receive support from geographers and others like Ctesias, Ephorus, Strabo, Tacitus, and the Epicureans. The last Greek advocate of the traditional cosmology was Cosmas Indicopleustes.

In ancient Greek mythology and religion, Persephone (/pərˈsɛfəniː/ pər-SEF-ə-nee; Greek: Περσεφόνη, romanized: Persephónē, classical pronunciation: [per.se.pʰó.nɛː]), also called Kore (/ˈkɔːriː/ KOR-ee; Greek: Κόρη, romanized: Kórē, lit. 'the maiden') or Cora, is the daughter of Zeus and Demeter. She became the queen of the underworld after her abduction by her uncle Hades, the king of the underworld, who would later take her into marriage. The myth of her abduction, her sojourn in the underworld, and her cyclical return to the surface represents her functions as the embodiment of spring and the personification of vegetation, especially grain crops, which disappear into the earth when sown, sprout from the earth in spring, and are harvested when fully grown.

In Classical Greek art, Persephone is invariably portrayed robed, often carrying a sheaf of grain. She may appear as a mystical divinity with a sceptre and a little box, but she was mostly represented in the process of being carried off by Hades.

Serapis or Sarapis is a Graeco-Egyptian god. A syncretic deity derived from the worship of the Egyptian Osiris and Apis, Serapis was extensively popularized in the third century BC on the orders of Greek Pharaoh Ptolemy I Soter, as a means to unify the Greek and Egyptian subjects of the Ptolemaic Kingdom.

The cultus of Serapis was spread as a matter of deliberate policy by subsequent Ptolemaic kings. Serapis continued to increase in popularity during the Roman Empire, often replacing Osiris as the consort of Isis in temples outside Egypt.Alongside his Egyptian roots he gained attributes from other deities, such as chthonic powers linked to the Greek Hades and Demeter, and benevolence derived from associations with Dionysus.

Ancient Greek art is the visual and applied arts, as well as the architecture, produced by the Hellenes or Greek peoples from the start of the Iron Age to the Hellenistic period, ending with Roman conquest of Greece at the Battle of Corinth in 146 BCE. It stands out among that of other ancient cultures for its development of naturalistic but idealized depictions of the human body, in which largely nude male figures were generally the focus of innovation. The rate of stylistic development between about 750 and 300 BC was remarkable by ancient standards, and in surviving works is best seen in sculpture. There were important innovations in painting, which have to be essentially reconstructed due to the lack of original survivals of quality, other than the distinct field of painted pottery.

Greek architecture, technically very simple, established a harmonious style with numerous detailed conventions that were largely adopted by Roman architecture and are still followed in some modern buildings. It used a vocabulary of ornament that was shared with pottery, metalwork and other media, and had an enormous influence on Eurasian art, especially after Buddhism carried it beyond the expanded Greek world created by Alexander the Great. The social context of Greek art included radical political developments and a great increase in prosperity; the equally impressive Greek achievements in philosophy, literature and other fields are well known.

The Eleusinian Mysteries (Greek: Ἐλευσίνια Μυστήρια, romanized: Eleusínia Mystḗria) were initiations held every year for the cult of Demeter and Persephone based at the Panhellenic Sanctuary of Eleusis in ancient Greece. They are considered the "most famous of the secret religious rites of ancient Greece". Their basis was a Bronze Age agrarian cult, and there is some evidence that they were derived from the religious practices of the Mycenean period. The Mysteries represented the myth of the abduction of Persephone from her mother Demeter by the king of the underworld Hades, in a cycle with three phases: the descent (loss), the search, and the ascent, with the main theme being the ascent (ἄνοδος) of Persephone and the reunion with her mother. It was a major festival during the Hellenic era, and later spread to Rome.

The rites, ceremonies, and beliefs were kept secret and consistently preserved from antiquity. For the initiated, the rebirth of Persephone symbolized the eternity of life which flows from generation to generation, and they believed that they would have a reward in the afterlife. There are many paintings and pieces of pottery that depict various aspects of the Mysteries. Since the Mysteries involved visions and conjuring of an afterlife, some scholars believe that the power and longevity of the Eleusinian Mysteries, a consistent set of rites, ceremonies and experiences that spanned two millennia, came from psychedelic drugs . The name of the town, Eleusis, seems to be pre-Greek, and is likely a counterpart with Elysium and the goddess Eileithyia.

In Greek mythology, the underworld or Hades (Ancient Greek: ᾍδης, romanized: Háidēs) is a distinct realm (one of the three realms that make up the cosmos) where an individual goes after death. The earliest idea of afterlife in Greek myth is that, at the moment of death, an individual's essence (psyche) is separated from the corpse and transported to the underworld. In early mythology (e.g., Homer's Iliad and Odyssey) the dead were indiscriminately grouped together and led a shadowy post-existence; however, in later mythology (e.g., Platonic philosophy) elements of post-mortem judgment began to emerge with good and bad people being separated (both spatially and with regards to treatment).

The underworld itself—commonly referred to as Hades, after its patron god, but also known by various metonyms—is described as being located at the periphery of the earth, either associated with the outer limits of the ocean (i.e., Oceanus, again also a god) or beneath the earth. Darkness and a lack of sunlight are common features associated with the underworld and, in this way, provide a direct contrast to both the 'normality' of the land of the living (where the sun shines) and also with the brightness associated with Mount Olympus (the realm of the gods). The underworld is also considered to be an invisible realm, which is understood both in relation to the permanent state of darkness but also a potential etymological link with Hades as the 'unseen place'. The underworld is made solely for the dead and so mortals do not enter it – with only a few heroic exceptions (who undertook a mythical catabasis: Heracles, Theseus, Orpheus, possibly also Odysseus, and in later Roman depictions Aeneas).

In Greek mythology, the Titans (Ancient Greek: Τιτᾶνες, Tītânes; singular: Τιτάν, Tītā́n) were the deities that preceded the Olympians. According to the Theogony of Hesiod, they were the twelve children of the primordial deities Uranus (Sky) and Gaia (Earth). The six male Titans were Oceanus, Coeus, Crius, Hyperion, Iapetus, and Cronus, and the six female Titans (called the Titanesses; Ancient Greek: Τιτανίδες, Tītānídes; singular: Τιτανίς, Tītānís) were Theia, Rhea, Themis, Mnemosyne, Phoebe, and Tethys.

After Cronus married his sister Rhea, she bore the first generation of Olympians: the six siblings Zeus, Hera, Poseidon, Demeter, Hades, and Hestia. Certain other children of the Titans, such as Prometheus, Atlas, Helios, and Leto, are sometimes also called Titans.
