What this dot point is asking
NESA expects you to describe Roman state religion in Pompeii and Herculaneum, the imperial cult and its civic role, the practice of household religion through the lararium, and the presence of foreign cults including Isis, Sabazius, and (more contentiously) early Judaism or Christianity. Strong answers cite specific temples, inscriptions, and household shrines, and engage with Mary Beard's reading of Pompeian religion as syncretic.
The answer
State religion: the Capitoline Triad and the Forum temples
The Roman state religion centred on the Capitoline Triad: Jupiter Optimus Maximus, Juno, and Minerva. At Pompeii, the Capitolium (also called the Temple of Jupiter) stood at the north end of the Forum. After the AD 62 earthquake it was severely damaged and still under reconstruction in AD 79.
Other Forum temples include:
- The Temple of Apollo (oldest, with Greek origins, Tuscan-Doric mix)
- The Temple of the Genius of Augustus (financed by Mamia, the public priestess)
- The Temple of Vespasian (under construction in AD 79)
- The Sanctuary of the Lares Publici
Outside the Forum, the Temple of Venus on the south-west cliff overlooking the sea reflected Venus's role as patron deity of Pompeii (Venus Pompeiana, "Venus of Pompeii"). The temple was severely damaged in AD 62.
The imperial cult
Following the principate of Augustus, the imperial cult became central to civic religion. The Building of Eumachia on the east side of the Forum was dedicated to Concordia Augusta and Pietas; its dedicatory inscription names Eumachia, public priestess, as the donor. The Temple of the Genius of Augustus housed images of the emperor's protective deity.
Freedmen could not hold magistracies but could become Augustales, priests of the imperial cult. The Hall of the Augustales at Herculaneum preserves the painted frescoes (Hercules and Achelous) commissioned by this freedmen's organisation. The Augustalia was a recognised civic body in both cities.
Household religion: the lararium
Almost every Pompeian house preserves a lararium, the household shrine for the Lares (guardian deities of the household and crossroads), the Penates (gods of the storeroom), and the Genius of the paterfamilias (the spirit of the head of household).
The lararium of the House of the Vettii is the most famous example. The painted shrine shows two dancing Lares flanking the Genius in a toga, holding a patera (offering bowl). Two serpents (agathodaimones, good spirits of the place) flank an altar at the base.
Less wealthy households had simpler painted niches or freestanding bronze figurines. Carbonised garlands, traces of incense, and food offerings have been recovered at several lararia. Daily worship was a family affair; Petronius (Satyricon 60) describes the freedman Trimalchio's household devotions with comic exaggeration.
Compitalia shrines (street-corner shrines) marked neighbourhood crossroads and were maintained by local vici (neighbourhood associations).
The cult of Isis
The Temple of Isis was rebuilt after the AD 62 earthquake. The dedicatory inscription is among the most-quoted Pompeian inscriptions:
"N(umerius) Popidius N(umerii) f(ilius) Celsinus aedem Isidis terrae motu conlapsam a fundamento p(ecunia) s(ua) restituit. Hunc decuriones ob liberalitatem cum esset annorum sex ordini suo gratis adlegerunt."
("Numerius Popidius Celsinus, son of Numerius, restored from the foundations at his own expense the Temple of Isis that had collapsed in the earthquake. In return for his generosity, the decurions enrolled him in their order free of charge, although he was only six years old.")
The dedication reveals that wealthy freedmen used religious benefaction to acquire civic status for their children. The temple itself includes a porticoed courtyard, a sacrarium, an underground initiation chamber (megaron), and elaborate frescoes of Isiac processions, the Nile, priests, and Egyptian symbols (sistra, ibis, lotus).
The cult of Isis was an officially recognised foreign religion (sacra peregrina) and combined Egyptian iconography with Roman mystery-cult practice. The "isiaci" (devotees of Isis) appear in the electoral programmata endorsing candidates.
Other foreign cults
Sabazius. Bronze "Hands of Sabazius" (votive hands covered with religious symbols including a serpent, pine cone, and frog) have been found at Pompeii. Sabazius was a Phrygian-Thracian deity syncretised with Jupiter in the Roman period.
Cybele (Magna Mater). Some inscriptions and frescoes attest a presence, though the cult is less archaeologically visible than Isis.
Mithras. A claimed Mithraeum at Pompeii has not been securely identified. The cult was beginning to spread in the western empire in the late 1st century AD but is more visible at Roman frontier sites.
Judaism. A few graffiti suggest Jewish presence ("Sodoma, Gomora"; possible Jewish names in inscriptions). The evidence is fragmentary.
Christianity. A contested "Christianos" graffito and a possible cross-shape impression in stucco at Herculaneum have led to debate about early Christian presence. Mary Beard treats the evidence as suggestive but not conclusive.

Historiography
Mary Beard (Pompeii, 2008; SPQR, 2015) treats Pompeian religion as syncretic. The Roman state cult, household worship, the imperial cult, and Isis coexisted; "Pompeian religion" is a category of overlapping practices, not a single system.
Alison Cooley (Pompeii and Herculaneum: A Sourcebook, 2014) provides the canonical translation of the religious inscriptions.
John Bodel (Household and Family Religion in Antiquity, 2008) emphasises the centrality of household religion in everyday Roman piety.
How to read a source on this topic
Section I sources on religion typically include photographs of lararia, the Vettii painted shrine, the Temple of Isis frescoes, the Eumachia inscription, or the Isis dedicatory inscription. Three reading habits.
First, identify the religious register. State religion (Capitoline Triad), imperial cult (Augustales, Eumachia building), household worship (lararium), and foreign cult (Isis) are distinct categories with different evidence types. State which applies.
Second, decode the dedicatory formula. The Isis temple inscription (Numerius Popidius Celsinus, age 6) reveals freedman social mobility through religious benefaction. The Eumachia inscription reveals female public benefaction. The formula carries the social meaning.
Third, weigh the cult's prominence. Isis at Pompeii is unusually well-evidenced; this does not mean Isis was the dominant cult. Most Pompeians worshipped at the lararium daily and visited Forum temples on civic occasions. Don't overstate the foreign cults.
Common exam traps
Treating Isis as marginal. The Temple of Isis is one of the best-preserved religious buildings at Pompeii and is asked about repeatedly. Know the Celsinus inscription verbatim.
Confusing Lares and Penates. Lares: guardian deities (household + crossroads). Penates: storeroom and prosperity deities. Both appear at the lararium.
Skipping the AD 62 earthquake. Almost every Forum temple was damaged; reconstruction was incomplete in AD 79. This is essential context for any "religion" question.
Overclaiming Christianity. The evidence is fragmentary and contested. State it as such; don't treat the Christianos graffito as decisive.
In one sentence
Religion in Pompeii and Herculaneum combined the Capitoline Triad and Forum temples of Roman state cult, the imperial cult centred on the Eumachia building and the Augustales freedmen priesthood, near-universal household worship at the lararium (with the House of the Vettii as the iconic example), and a notable foreign cult of Isis whose temple was restored after the AD 62 earthquake by the six-year-old freedman's son Numerius Popidius Celsinus, in a syncretic religious landscape that Beard and Cooley have reconstructed from inscriptions, archaeology, and household shrines.

2021 HSC (verbatim)5 marksOutline the features of household religion in Pompeii. Support your response using Source A.Show worked answer →
A 5-mark response on household religion needs three to four features with named evidence.
The lararium. Most houses had a household shrine called a lararium, either a niche in the wall (more common in modest houses) or an elaborate aedicula in the form of a miniature temple. The lararium of the House of the Vettii is the most famous example: a painted shrine showing two Lares (guardian deities) flanking the Genius (the spirit of the head of household) in a toga.
The household deities. The Lares (guardians of the household and crossroads), the Penates (gods of the storeroom and the household's prosperity), and the Genius of the paterfamilias were the core domestic deities. Offerings of incense, wine, garlands, and food were placed daily at the shrine.
The serpent imagery. The serpent in the lararium painting represents the agathodaimon (good spirit) of the place. The lararium of the Vettii includes two such serpents at the base of the painted altar.
Crossroads shrines. Beyond the household, street-corner shrines (compitalia shrines) marked neighbourhood boundaries. Several have been preserved in situ along the Pompeian streets.
Daily practice. Petronius (Satyricon 60) describes Trimalchio's household worship; the literary parallel matches the archaeological evidence. The historian John Bodel (Household and Family Religion in Antiquity, 2008) treats the lararium as the most reliable evidence of mass religious practice in Roman society.
Markers reward the lararium, named deities (Lares, Penates, Genius), the Vettii example, and at least one historian or ancient source.
Practice (NESA)7 marksExplain the evidence for foreign cults in Pompeii. Support your response using one source.Show worked answer →
A 7-mark response on foreign cults needs three to four cults with named sites and evidence.
The Temple of Isis. Re-erected after the AD 62 earthquake (the dedicatory inscription names the six-year-old Numerius Popidius Celsinus, whose freedman father funded the restoration; the inscription records the son's reward of decurional status). The temple includes a sacrarium, a courtyard, painted frescoes of Egyptian motifs (Isis, Osiris, the Nile), and a megaron (initiation chamber). Wall paintings of Isis processions survive.
The Sabazius cult. Bronze "Hands of Sabazius" (votive hands covered with religious symbols) have been found at Pompeii. The cult of Sabazius (a Phrygian-Thracian god syncretised with Jupiter) is attested across the Roman empire but rare archaeologically; the Pompeian bronze hands are an important survival.
The cult of the Vesonius family Mithra (debated). A mithraeum has been claimed at Pompeii but not securely identified; the cult was rising in the western empire during the late 1st century AD.
Judaism and Christianity. A graffito reading "SODOMA GOMORA" and the contested "Christianos" graffito raise the question of an early Christian or Jewish presence. The evidence is fragmentary and disputed. Mary Beard treats the evidence as suggestive but not conclusive.
Foreign motifs in domestic decoration. Egyptian-style frescoes appeared in several houses (the House of Loreius Tiburtinus has Isis imagery; the Villa of the Mysteries combines Dionysiac imagery with Egyptian motifs).
Historian. Alison Cooley (Pompeii: A Sourcebook, 2014) catalogues the inscriptions for foreign cults. Markers reward the Isis temple, at least one other cult, and a named historian.
