Vulcan

Also Known As: Latin *Volcanus*, later *Vulcanus*; consort *Maia Volcani* in the priestly prayer books; the imperial cult title *Volcanus Quietus*, “Vulcan at rest”; Etruscan smith-god *Sethlans*
Region/Culture: Southern Europe
Mythos: Roman Mythology
Primary Type/Nature: Gods and Deities
Mythical Attributes: He is fire in its destroying form, the fire that takes a city rather than the fire that cooks a dinner.
Role in Mythos: He is the god Rome housed outside its own walls on purpose, gave the burnt arms of defeated enemies, and asked every August to accept a substitute life instead of a human one.
Relation to Humans: On his festival the people threw living animals into a fire on their own behalf, buying themselves off. In the port of Ostia his priest outranked every other religious official in the town and decided what could and could not be built.

On the twenty-third of August the Romans lit a fire and threw living animals into it. Varro, listing the festivals, explains the day in a single clause and does not soften it: the people cast animals into the fire *pro se*, on their own behalf. A later tradition specifies small fish taken live from the Tiber, offered in place of human lives. Either way the logic is the same and it is not a metaphor. Fire takes what it wants. You give it something first, and hope the substitution holds.

That is Vulcan, and it explains almost everything odd about how Rome handled him. He is not a craftsman with a workshop. He is the fire that goes through a district of wooden apartment blocks in a summer wind, and Roman religion treated him as a hazard to be managed rather than a patron to be courted.

The management is visible in the town plan. Vitruvius, laying out the rules for siting temples, says that shrines of Vulcan should be placed outside the city, so that the power presiding over that element is drawn away by its rites and sacrifices. Mars goes outside too, and Venus by the gate. His temple in Rome stood in the Campus Martius, beyond the sacred boundary, and it was already old enough by 214 BC to be recorded as struck by lightning. The one Vulcan site inside the old city was not a temple at all but an open-air altar with a walled precinct at the foot of the Capitol, the Volcanal, whose foundation the antiquarians credited variously to Romulus and to Titus Tatius. It held a statue of Horatius Cocles, a bronze four-horse chariot Romulus was said to have brought back from Cameria, and a lotus tree that Pliny thought was as old as the city itself. Excavation there found a cut rock platform under four metres by three, probably the altar. Dionysius adds that in the earliest period the kings and the senate held their assemblies in the shrine of Vulcan a little above the Forum, which puts one of Rome’s oldest political spaces around an altar to the thing that could destroy it.

His Roman consort is not Venus, and the pairing everyone knows never appears in Roman worship at all. Aulus Gellius copied out the divine partners named in the pontiffs’ books and the old prayer collections, and the entry there is Maia of Vulcan. Beside her, in the same functional territory, stands Stata Mater, the Mother who stops, a goddess whose whole business was arresting fires. Her statue was set up in the Forum to protect the new pavement from burning, and her cult spread through the neighbourhoods; after Augustus reorganised the wards she is second only to the Lares in the local inscriptions. One of those inscriptions names her alongside Volcanus Quietus, Vulcan at rest. That epithet is the entire Roman theology in two words. The good version of this god is the one who is not doing anything.

Where Vulcan does receive something willingly, it is destruction put to Roman use. After defeating the Sabines, Tarquin burned the captured arms in a huge heap because the spoils had been vowed to Vulcan. The rule survived into the law of the battlefield: Livy records that a commander who has devoted himself and the enemy line to the underworld has the right to vow the enemy’s arms to Vulcan or to another god. Burning what you have taken is a way of making the destruction deliberate, and giving it to the god whose element it is.

There is also a strange and very local sweetness to him. Every June the praetor in charge of the city’s courts held games on the plain across the Tiber on behalf of the river fishermen, who kept the day as a holiday, and the small fish caught then went not to the market but to Vulcan’s own precinct. In Ostia, Rome’s port, the priest of Vulcan held an office with no real parallel: he was chosen for life, he outranked every other religious official in the town, he had junior magistrates under him, and permission to erect a new sacred building or a new statue of a foreign god had to come from him. A town whose entire wealth sat in wooden warehouses full of grain put the fire god at the head of its religion, which is either piety or actuarial sense.

His origins are genuinely obscure and the honest answer is that nobody has settled them. The Etruscan smith Sethlans wears the same kit, the conical cap, the hammer and the tongs, and shares nothing with him by name. An old proposal linked *Volcanus* to a Cretan Velchanos, but it rests on the resemblance between two words and on a suggestion made in the 1930s, and the Cretan figure is a vegetation deity who does not fit. Indo-European and Etruscan derivations are both still argued and neither has won. What can be said is that he is old at Rome: he has one of the twelve minor flaminates, a priest of his own, and a festival in the archaic calendar, which is more than Mercury or Venus can show.

The Greek Vulcan arrived on schedule with the rest. In 217 BC the Sibylline Books laid six couches for twelve gods, and the pairing they gave him is worth noticing: Vulcan with Vesta. Not with Venus, who was put on Mars’s couch. The Roman scheme read him as fire alongside the hearth, which is the right reading of what the Roman cult was about. The forge under the volcano, the net thrown over the adulterous lovers, the lame god thrown out of heaven, all of that is Greek and reaches Latin through poetry; Virgil’s version, where the Cyclopes hammer out the shield of Aeneas in a cavern under the Aeolian islands, is Augustan literature written for a purpose. Even the small habit that gets quoted as a Roman custom, working by lamplight from the twenty-third of August, turns out on inspection to be one man’s routine: the younger Pliny says his uncle began studying before dawn from the Volcanalia, and adds that it was not for any religious reason, he simply wanted the hours.

His power is total within its own element and useless outside it. He can take a warehouse district, an army’s captured weapons or the whole Forum, and Roman practice assumed he would, sooner or later. What he cannot do is anything else. He has no myth in Rome, no role in the foundation, no place in either triad, no oracle and no favour to grant beyond staying quiet. The only leverage anyone had over him was substitution, which is why the rite that survives him best is a crowd on a hot August evening putting something living into a fire and asking to be let off.

Frequently Asked Questions

Who was Vulcan in Roman mythology?

Vulcan was the Roman god of destructive fire, worshipped chiefly to keep him quiet. He had one of the twelve minor flaminates, an archaic open-air shrine called the Volcanal at the foot of the Capitol, and a festival on 23 August. His Roman consort in the priestly prayer books is Maia, not Venus.

Is Vulcan the same as Hephaestus?

They were identified, but the Roman cult is about fire as a danger rather than about metalworking. Roman religion sited his temples outside the walls to draw the fire risk away, gave him burned enemy weapons, and paired him with Vesta rather than Venus when the gods were arranged in couples in 217 BC. The forge under the volcano, the net and the fall from heaven are Greek stories that reached Latin through poetry.

What happened at the Volcanalia?

On 23 August the Romans threw living animals into a fire on their own behalf, offering them in place of themselves. Varro records the rite plainly, and a later tradition specifies small live fish taken from the Tiber. The Elder Pliny is also said to have begun his pre-dawn study by lamplight from this date, though his nephew notes that this was habit rather than religion.

Why were Vulcan’s temples built outside the city?

Vitruvius states the reason directly: shrines of Vulcan belong outside the walls so that the power presiding over fire is drawn away from the city by its own rites and sacrifices. His Roman temple stood in the Campus Martius beyond the sacred boundary. The one exception inside the old city was the Volcanal, an open-air altar rather than a roofed temple.

Who was Vulcan’s wife in Roman religion?

In the pontiffs’ prayer formulas recorded by Aulus Gellius, Vulcan’s consort is Maia. The marriage to Venus belongs to Greek stories about Hephaestus and Aphrodite and had no place in Roman worship. A related Roman figure is Stata Mater, the goddess who stops fires, who appears in one inscription alongside the title Volcanus Quietus, Vulcan at rest.
