Greek underworld in the context of "Erebus"

In Greek mythology, Styx (/ˈstɪks/ ; Ancient Greek: Στύξ [stýks]; lit. "Shuddering"), also called the River Styx, is a goddess and one of the rivers of the Greek Underworld. Her parents were the Titans Oceanus and Tethys, and she was the wife of the Titan Pallas and the mother of Zelus, Nike, Kratos, and Bia. She sided with Zeus in his war against the Titans, and because of this, to honor her, Zeus decreed that the solemn oaths of the gods be sworn by the water of Styx.

Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the god of freshwater and the sea in the Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-inspired tradition, he is a brother of Jupiter and Pluto, with whom he presides over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife.

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, Neptunalia, took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, Neptunus equestris, who was also a patron of horse-racing.

In ancient Greek religion and mythology, Demeter (/dɪˈmiːtər/; Attic: Δημήτηρ Dēmḗtēr [dɛːmɛ́ːtɛːr]; Doric: Δαμάτηρ Dāmā́tēr) is the Olympian goddess of the harvest and agriculture, presiding over crops, grains, food, and the fertility of the earth. Although Demeter is mostly known as a grain goddess, she also appeared as a goddess of health, birth, and marriage, and had connections to the Underworld. She is also called Deo (Δηώ Dēṓ).

In Greek tradition, Demeter is the second child of the Titans Rhea and Cronus, and sister to Hestia, Hera, Hades, Poseidon, and Zeus. Like her other siblings except Zeus, she was swallowed by her father as an infant and rescued by Zeus. Through Zeus, she became the mother of Persephone, a fertility goddess and resurrection deity. One of the most notable Homeric Hymns, the Homeric Hymn to Demeter, tells the story of Persephone's abduction by Hades and Demeter's search for her. When Hades, the King of the Underworld, wished to make Persephone his wife, he abducted her from a field while she was picking flowers, with Zeus's leave. Demeter searched everywhere to find her missing daughter to no avail until she was informed that Hades had taken her to the Underworld. In response, Demeter neglected her duties as goddess of agriculture, plunging the earth into a deadly famine where nothing would grow, causing mortals to die. Zeus ordered Hades to return Persephone to her mother to avert the disaster. However, because Persephone had eaten food from the Underworld, she could not stay with Demeter forever, but had to divide the year between her mother and her husband, explaining the seasonal cycle as Demeter does not let plants grow while Persephone is gone.

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.

Hades (/ˈheɪdiːz/; Ancient Greek: ᾍδης, romanized: Hā́idēs, Attic Greek: [háːi̯dεːs], later [háːdeːs]), in the ancient Greek religion and mythology, is the god of the dead and riches and the King of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although this also made him the last son to be regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated, overthrew, and replaced their father's generation of gods, the Titans, and claimed joint sovereignty over the cosmos. Hades received the underworld, Zeus the sky, and Poseidon the sea, with the solid earth, which was long the domain of Gaia, available to all three concurrently. In artistic depictions, Hades is typically portrayed holding a bidentand wearing his helm with Cerberus, the three-headed guard-dog of the underworld, standing at his side.

Roman-era mythographers eventually equated the Etruscan god Aita,and the Roman gods Dis Pater and Orcus, with Hades, and merged all these figures into Pluto, a Latinisation of Plouton (Ancient Greek: Πλούτων, romanized: Ploútōn), itself a euphemistic title (meaning "the rich one") often given to Hades.

Aeacus (/ˈiːəkəs/; also spelled Eacus; Ancient Greek: Αἰακός) was a king of the island of Aegina in Greek mythology. He was a son of Zeus and the nymph Aegina, and the father of the heroes Peleus and Telamon. According to legend, he was famous for his justice, and after he died he became one of the three judges in the underworld alongside Minos and Rhadamanthus. In another story, he assisted Poseidon and Apollo in building the walls of Troy.

He had sanctuaries in Athens and Aegina, and the Aeginetan festival of the Aeacea (Αἰάκεια) was celebrated in his honour.

In Greek mythology, Minos (/ˈmaɪnɒs, -nəs/ ; Greek: Μίνως, [mǐːnɔːs]) was a king of Crete, son of Zeus and Europa. Every nine years, he made King Aegeus pick seven young boys and seven young girls to be sent to Daedalus's creation, the labyrinth, to be eaten by the Minotaur. After his death, King Minos became a judge of the dead in the underworld alongside Rhadamanthus and Aeacus.

Archeologist Sir Arthur Evans used King Minos as the namesake for the Minoan civilization of Crete. The Minoan palace at Knossos is sometimes referred to as the Palace of Minos though there is no evidence that Minos was a real person.

In Greek mythology, Orpheus (/ˈɔːrfiːəs, ˈɔːrfjuːs/ ; Ancient Greek: Ὀρφεύς, classical pronunciation: [or.pʰeú̯s]) was a bard, legendary musician and prophet. He was also a renowned poet and, according to legend, travelled with Jason and the Argonauts in search of the Golden Fleece, and descended into the underworld to recover his lost wife, Eurydice.

The major stories about him are centered on his ability to charm all living things and even stones with his music (the usual scene in Orpheus mosaics), his attempt to retrieve his wife Eurydice from the underworld, and his death at the hands of the maenads of Dionysus, who got tired of his mourning for his late wife Eurydice. As an archetype of the inspired singer, Orpheus is one of the most significant figures in the reception of classical mythology in Western culture, portrayed or alluded to in countless forms of art and popular culture including poetry, film, opera, music, and painting.
