Hestia in the context of "Greek primordial deities"

Religious practices in ancient Greece encompassed a collection of beliefs, rituals, and mythology, in the form of both popular public religion and cult practices. The application of the modern concept of "religion" to ancient cultures has been questioned as anachronistic. The ancient Greeks did not have a word for 'religion' in the modern sense. Likewise, no Greek writer is known to have classified either the gods or the cult practices into separate 'religions'. Instead, for example, Herodotus speaks of the Hellenes as having "common shrines of the gods and sacrifices, and the same kinds of customs".

Most ancient Greeks recognized the twelve major Olympian gods and goddesses—Zeus, Hera, Poseidon, Demeter, Athena, Ares, Aphrodite, Apollo, Artemis, Hephaestus, Hermes, and either Hestia or Dionysus—although philosophies such as Stoicism and some forms of Platonism used language that seems to assume a single transcendent deity. The worship of these deities, and several others, was found across the Greek world, though they often have different epithets that distinguished aspects of the deity, and often reflect the absorption of other local deities into the pan-Hellenic scheme.

In ancient Greek religion and mythology, the twelve Olympians are the major deities of the Greek pantheon, commonly considered to be Zeus, Poseidon, Hera, Demeter, Aphrodite, Athena, Artemis, Apollo, Ares, Hephaestus, Hermes, and either Hestia or Dionysus. They were called Olympians because, according to tradition, they resided on Mount Olympus.

Besides the twelve Olympians, there were many other cultic groupings of twelve gods.

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.

Vesta (Classical Latin: [ˈwɛs.ta]) is the virgin goddess of the hearth, home, and family in Roman religion. She was rarely depicted in human form, and was more often represented by the fire of her temple in the Forum Romanum. Entry to her temple was permitted only to her priestesses, the Vestal Virgins. Their virginity was deemed essential to Rome's survival; if found guilty of inchastity, they were buried or entombed alive. As Vesta was considered a guardian of the Roman people, her festival, the Vestalia (7–15 June), was regarded as one of the most important Roman holidays. During the Vestalia privileged matrons walked barefoot through the city to the temple, where they presented food-offerings. Such was Vesta's importance to Roman religion that following the rise of Christianity, hers was one of the last non-Christian cults still active, until it was forcibly disbanded by the Christian emperor Theodosius I in AD 391.

The myths depicting Vesta and her priestesses were few; the most notable of them were tales of miraculous impregnation of a virgin priestess by a phallus appearing in the flames of the sacred hearth — the manifestation of the goddess combined with a male supernatural being. In some Roman traditions, Rome's founders Romulus and Remus and the benevolent king Servius Tullius were conceived in this way. Vesta was among the Dii Consentes, twelve of the most honored gods in the Roman pantheon. She was the daughter of Saturn and Ops, and sister of Jupiter, Neptune, Pluto, Juno, and Ceres. Her Greek equivalent is Hestia.

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.

In Greek mythology, Rhea, Rhia or Rheia (/ˈriːə/; Ancient Greek: Ῥέα [r̥é.aː] or Ῥεία [r̥ěː.aː]) was one of the Titans, the children of Uranus (Sky) and Gaia (Earth). She was the sister and wife of Cronus, and by him, the mother of the six Olympians: Hestia, Demeter, Hera, Hades, Poseidon, and Zeus.

When Cronus learnt that he was destined to be overthrown by one of his children like his father before him, he swallowed all the children Rhea bore as soon as they were born. When Rhea had her sixth and final child, Zeus, she spirited him away and hid him in Crete, giving Cronus a rock to swallow instead, thus saving her youngest son who would go on to challenge his father's rule and rescue the rest of his siblings. Following Zeus's defeat of Cronus and the rise of the Olympian gods into power, Rhea withdraws from her role as the queen of the gods to become a supporting figure on Mount Olympus. She has some roles in the new Olympian era. She attended the birth of her grandson Apollo and raised her other grandson Dionysus. After Persephone was abducted by Hades, Rhea was sent to Demeter by Zeus. In the myth of Pelops, she resurrects the unfortunate youth after he has been slain.

In Greek and Roman mythology, several goddesses are distinguished by their perpetual virginity. These goddesses included the Greek deities Hestia, Athena, and Artemis, along with their Roman equivalents, Vesta, Minerva, and Diana. In some instances, the inviolability of these goddesses was simply a detail of their mythology, while in other cases virginity was also associated with their worship and religious rites.
