Vulcan (mythology) in the context of Roman mythology

Hephaestus (UK: /hɪˈfiːstəs/ hih-FEE-stəs, US: /hɪˈfɛstəs/ hih-FES-təs; eight spellings; Ancient Greek: Ἥφαιστος, romanized: Hḗphaistos) is the Greek god of artisans, blacksmiths, carpenters, craftsmen, fire, metallurgy, metalworking, sculpture, and volcanoes. In Greek mythology, Hephaestus was the son of Hera, either on her own or by her husband Zeus. He was cast off Mount Olympus by his mother Hera because of his lameness, the result of a congenital impairment; or in another account, by Zeus for protecting Hera from his advances (in which case his lameness would have been the result of his fall rather than the reason for it).

As a smithing god, Hephaestus created all the weapons of the gods in Olympus. He served as the blacksmith of the gods, and was worshipped in the manufacturing and industrial centres of Greece, particularly Athens. The cult of Hephaestus was based in Lemnos. Hephaestus's symbols are a smith's hammer, anvil, and a pair of tongs. In Rome, he was equated with Vulcan.

Juno (English: /ˈdʒuːnoʊ/ JOO-noh; Latin: Iūnō [ˈjuːnoː]) is a goddess in the ancient Roman religion, the protector and special counsellor of the state. She equates to Hera, queen of the gods in Greek mythology and a goddess of love and marriage. A daughter of Saturn and Ops, she is the sister and wife of Jupiter and the mother of Mars, Vulcan, Bellona, Lucina and Juventas. Like Hera, her sacred animal is the peacock. Her Etruscan counterpart is Uni, and she was said to also watch over the women of Rome. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("Queen") and is a member of the Capitoline Triad (Juno Capitolina), centered on the Capitoline Hill in Rome, with also includes Jupiter, and Minerva, goddess of wisdom.

Juno's own warlike aspect among the Romans is apparent in her attire. She was often shown armed and wearing a goatskin cloak. The traditional depiction of this warlike aspect was assimilated from the Greek goddess Athena, who bore a goatskin, or a goatskin shield, called the Aegis. Juno was also shown wearing a diadem.

Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological, geophysical and geochemical phenomena (volcanism). The term volcanology is derived from the Latin word vulcan. Vulcan was the ancient Roman god of fire.

A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions. Volcanologists frequently visit volcanoes, especially active ones, to observe volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples. One major focus of enquiry is the prediction of eruptions; there is currently no accurate way to do this, but predicting or forecasting eruptions, like predicting earthquakes, could save many lives.

In Etruscan mythology, Sethlans was the god of fire, the forge, metalworking, and by extension craftsmanship in general, the equivalent, though their names share no etymology, to Greek Hephaestus, Egyptian Ptah and the Roman Vulcan. Sethlans is one of the indigenous Etruscan gods. In Etruscan arts Sethlans may be identified by his tools, the hammer and tongs of the blacksmith, and by the pileus or conical cap he wears.

His association with order and technical skill made him essential to rituals involving material production, such as weapon or tool creation, reflecting the Etruscan reverence for divine precision and manual labor.

The Phlegraean Fields (Italian: Campi Flegrei, Italian: [ˈkampi fleˈɡrɛi]; Neapolitan: Campe Flegree) is a large volcanic caldera west of Naples, Italy. The Neapolitan Yellow Tuff eruption (about 12ka BP) produced just 50 cubic kilometers. It is, however, one of relatively few volcanoes large enough to form a caldera. It is part of the Campanian volcanic arc, which includes Mount Vesuvius, about 9 km (6 miles) east of Naples. The Phlegraean Fields is monitored by the Vesuvius Observatory. Part of the city of Naples is built over it.The Phlegraean Fields' largest known eruptions have an estimated volcanic explosivity index (VEI) of 7. It is often called a supervolcano in popular media, although the accepted definition for that term is a volcano that has had an eruption with a VEI of 8, the highest level.

The area of the caldera consists of 24 craters and volcanic edifices. Most of them lie under the Gulf of Naples. There are effusive gaseous manifestations in the Solfatara crater, which was believed in ancient Rome to be the home of Vulcan, the god of fire. The area features bradyseismic phenomena, which are most evident at the Macellum of Pozzuoli, misidentified by 18th-century excavators as a temple of Serapis: bands of boreholes left by marine molluscs on marble columns show that the level of the site in relation to sea level has varied. Hydrothermal activity can still be observed at Lucrino, Agnano and the town of Pozzuoli.

Sacred mountains are central to certain religions, and are usually the subjects of many legends. For many, the most symbolic aspect of a mountain is the peak because it is believed that it is closest to heaven or other religious realms. Many religions have traditions centered on sacred mountains, which either are or were considered holy (such as Mount Olympus in Greek mythology) or are related to famous events (like Mount Sinai in Judaism and descendant religions or Mount Kailash, Mount Meru in Hinduism). In some cases, the sacred mountain is purely mythical, like the Hara Berezaiti in Zoroastrianism. Mount Kailash is believed to be the abode of the deities Shiva and Parvati, and is considered sacred in four religions: Hinduism, Bon, Buddhism, and Jainism. Volcanoes, such as Mount Etna in Italy, were also considered sacred, Mount Etna being believed to have been the home of Vulcan, the Roman god of fire and the forge.
