Hephaestus in the context of "Iphistiadai"

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.

Zeus (/zjuːs/, Ancient Greek: Ζεύς) is the chief deity of the Greek pantheon. He is a sky and thunder god in ancient Greek religion and mythology, who rules as king of the gods on Mount Olympus.

Zeus is the child of Cronus and Rhea, the youngest of his siblings to be born, though sometimes reckoned the eldest as the others required disgorging from Cronus's stomach. In most traditions, he is married to Hera, by whom he is usually said to have fathered Ares, Eileithyia, Hebe, and Hephaestus. At the oracle of Dodona, his consort was said to be Dione, by whom the Iliad states that he fathered Aphrodite. According to the Theogony, Zeus's first wife was Metis, by whom he had Athena. Zeus was also infamous for his erotic escapades. These resulted in many divine and heroic offspring, including Apollo, Artemis, Hermes, Persephone, Dionysus, Perseus, Heracles, Helen of Troy, Minos, and the Muses.

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 Greek mythology, Kratos (Ancient Greek: Κράτος, lit. 'power, strength') also known as Cratus or Cratos, is the divine personification of strength. He is the son of Pallas and Styx. Kratos and his siblings Nike ('Victory'), Bia ('Force'), and Zelus ('Glory') are all the personification of a specific trait. Kratos is first mentioned alongside his siblings in Hesiod's Theogony. According to Hesiod, Kratos and his siblings dwell with Zeus because their mother Styx came to him first to request a position in his regime, so he honored her and her children with exalted positions. Kratos and his sister Bia are best known for their appearance in the opening scene of Aeschylus' Prometheus Bound. Acting as agents of Zeus, they lead the captive Titan Prometheus on stage. Kratos compels the mild-mannered blacksmith god Hephaestus to chain Prometheus to a rock as punishment for his theft of fire.

Kratos is characterized as brutal and merciless, repeatedly mocking both Hephaestus and Prometheus' advocacy against the use of unnecessary violence. He defends Zeus' oppressive rule and predicts that Prometheus will never escape his bonds. In Aeschylus' Libation Bearers, Electra calls upon Kratos, Dike ("Justice"), and Zeus to aid her brother Orestes in avenging the murder of their father Agamemnon. Kratos and Bia appear in a late fifth-century BC red-figure Attic skyphos of the punishment of Ixion, possibly based on a scene from a lost tragedy by Euripides. They also appear in late eighteenth and nineteenth-century Romantic depictions and adaptations of the binding of Prometheus.

In Greek mythology and later Roman mythology, the Cyclopes (/saɪˈkloʊpiːz/ sy-KLOH-peez; Greek: Κύκλωπες, Kýklōpes, "Circle-eyes" or "Round-eyes"; singular Cyclops /ˈsaɪklɒps/ SY-klops; Κύκλωψ, Kýklōps) are giant one-eyed creatures. Three groups of Cyclopes can be distinguished. In Hesiod's Theogony, the Cyclopes are the three brothers, Brontes, Steropes, and Arges, who made Zeus's weapon, the thunderbolt. In Homer's Odyssey, they are an uncivilized group of shepherds, the brethren of Polyphemus encountered by Odysseus. A third group of Cyclopes reputedly built the Cyclopean walls of Mycenae and Tiryns.

In Cyclops, the fifth-century BC play by Euripides, a chorus of satyrs offers comic relief based on the encounter of Odysseus and Polyphemus. The third-century BC poet Callimachus makes the Hesiodic Cyclopes the assistants of smith-god Hephaestus, as does Virgil in the Latin epic Aeneid, where he seems to equate the Hesiodic and Homeric Cyclopes.

Vulcan (Latin: Vulcanus, in archaically retained spelling also Volcanus, both pronounced [wʊɫˈkaːnʊs]) is the god of fire including the fire of volcanoes, deserts, metalworking and the forge in ancient Roman religion and myth. He is often depicted with a blacksmith's hammer. The Vulcanalia was the annual festival held August 23 in his honor. His Greek counterpart is Hephaestus, the god of fire and smithery. In Etruscan religion, he is identified with Sethlans.

Vulcan belongs to the most ancient stage of Roman religion: Varro, the ancient Roman scholar and writer, citing the Annales Maximi, records that king Titus Tatius dedicated altars to a series of deities including Vulcan.

In Greek mythology, Pandora was the first human woman created by Hephaestus on the instructions of Zeus. As Hesiod related it, each god cooperated by giving her unique gifts. Her other name—inscribed against her figure on a white-ground kylix in the British Museum—is Anesidora (Ancient Greek: Ἀνησιδώρα), "she who sends up gifts" (up implying "from below" within the earth).

The Pandora myth is a kind of theodicy, addressing the question of why there is evil in the world, according to which, Pandora opened a jar (pithos; commonly referred to as "Pandora's box") releasing all the evils of humanity. It has been argued that Hesiod's interpretation of Pandora's story went on to influence both Jewish and Christian theology and so perpetuated her bad reputation into the Renaissance. Later poets, dramatists, painters and sculptors made her their subject.
