The Priest of Jupiter
Supreme Pontiff
In the intricate religious hierarchy of ancient Rome, the Flamen Dialis held the esteemed position of the high priest dedicated to Jupiter, the king of the gods. This role was not merely ceremonial; it placed the Flamen Dialis at the apex of Roman religious authority, second only to the Rex Sacrorum (King of Sacrifices) and above other major priestly colleges like the Pontifices and Augurs.
Sacred Origins
Tradition attributes the establishment of the Flamen Dialis, along with the other flamines maiores (major priests), to Numa Pompilius, the second king of Rome. This lineage suggests an ancient and foundational role in Roman religious practice, deeply intertwined with the very origins of the city's sacred institutions. Numa himself is said to have performed many of the rites associated with this office.
Hierarchical Standing
The Flamen Dialis occupied a unique position within the ordo sacerdotum (ranking of priests). While the Rex Sacrorum held precedence, the Flamen Dialis was officially ranked second. This elevated status was further emphasized by his proximity in rank to other flamines maiores such as the Flamen Martialis and Flamen Quirinalis, and the Pontifex Maximus, underscoring his critical importance in the Roman pantheon.
The Selection Process
Patrician Nomination
The path to becoming the Flamen Dialis was highly specific. When a vacancy arose, three individuals of patrician descent were nominated. A crucial requirement was that their parents must have been married according to the strict rites of confarreatio, the most formal and traditional Roman marriage ceremony. This ensured lineage and adherence to ancient customs.
Inauguration and Marriage
From the nominated candidates, one was selected by the Comitia (popular assembly). The chosen individual was then formally consecrated by the Pontifex Maximus. Furthermore, the candidate had to be married, and critically, married to a virgin, with their union also requiring the confarreatio ceremony. This dual requirement of lineage and marital purity was paramount.
Emancipation and Status
Upon consecration, the Flamen Dialis was emancipated from the authority of his father, becoming sui juris (legally independent). This granted him significant personal autonomy, reflecting his elevated status as a direct servant of Jupiter, detached from ordinary familial obligations and subject only to the divine and the sacred laws.
Distinguished Honors
Symbols of Office
The Flamen Dialis was distinguished by several unique honors. He alone among priests wore the apex, a distinctive conical hat symbolizing his office. He was also entitled to a lictor, an attendant who carried the fasces, signifying magisterial authority, and the right to wear the toga praetexta, a toga bordered with purple, indicating high status.
Senate and Banquets
The Flamen Dialis held an ex officio seat in the Roman Senate, a privilege asserted by Gaius Valerius Flaccus in 209 BC. This right, though sometimes contested, placed him among the highest echelons of Roman governance. At banquets, he held a position of honor, reclining above most others, second only to the Rex Sacrorum.
Sanctuary and Clemency
His house offered a unique form of sanctuary. If a person in bonds sought refuge, their chains were immediately removed and cast out. Similarly, if a condemned criminal encountered him, they were granted a respite for that day. These privileges highlighted the sacred inviolability and the perceived divine protection afforded to the high priest of Jupiter.
Sacred Restrictions & Taboos
Confinement and Purity
The Flamen Dialis was bound by numerous, often peculiar, restrictions designed to maintain his absolute purity and constant devotion to Jupiter. He could not be out of the city for more than a single night, a rule later modified by Augustus to allow two nights' absence. He was forbidden to sleep away from his own bed for three consecutive nights, effectively precluding him from governing a province.
Aversion to Iron and Horses
He was forbidden to mount or even touch a horse, reflecting an ancient aversion to cavalry and perhaps a connection to the earthly realm rather than the celestial. Similarly, he was forbidden to touch iron, a material associated with warfare and the mundane world, emphasizing his separation from secular affairs. He could not look upon an army marshalled outside the city's sacred boundary (the pomerium).
Daily Life Prohibitions
His daily life was governed by strict rules: he could not wear a ring unless it was plain and without stones, nor could he strip himself naked in the open air. Knots were forbidden in any part of his attire, and he could not walk paths overhung by vines. He was prohibited from touching flour, leaven, or leavened bread, and could not be present at a table without food, ensuring he never appeared wanting.
Contact with Death and Animals
The Flamen Dialis was forbidden to touch a dead body or enter a burial place, though he could attend a funeral procession. He was also prohibited from naming certain animals, including dogs and she-goats, and specific plants like ivy. Raw flesh was also forbidden. These prohibitions likely stemmed from ancient Indo-European traditions emphasizing ritual purity.
Ritual Hair and Burial
His hair could only be cut by a free man, and the clippings, along with his nail parings, were buried beneath an arbor felix (an auspicious tree). His bedstead had specific requirements, including being smeared with fine clay, and a box containing sacrificial cakes could not touch it. These meticulous details underscore the profound sacredness and isolation of his role.
The Flaminica Dialis
Wife of the High Priest
The Flaminica Dialis was the wife of the Flamen Dialis. Their union was central to the performance of certain rituals. Like her husband, she had to be a virgin at the time of their wedding, which had to be conducted through the strict confarreatio ceremony, a requirement shared by the wives of the other flamines maiores.
Shared Restrictions
The Flaminica Dialis was subject to restrictions similar to those of her husband. She was prohibited from mounting a staircase with more than three steps, possibly to prevent her ankles from being seen. Her hair was plaited in a conical form (tutulus) and could not be combed or arranged when she participated in specific rituals, such as that of the Argei.
Indissoluble Union
The marriage between the Flamen and Flaminica Dialis was traditionally indissoluble. Divorce was not permitted. If the Flaminica died, the Flamen Dialis was obliged to resign his office, highlighting the integral nature of their partnership in maintaining the sacred rites dedicated to Jupiter.
Notable Officials
Early Appointments
The office of Flamen Dialis was established early in Roman history, traditionally by Numa Pompilius. Historical records mention several individuals who held the post, though the exact dates and circumstances can be complex due to the nature of ancient records.
- Publius Cornelius Sulla (c. 279–270 BC)
- Lucius Quinctius (mid-3rd century BC)
- Publius Cornelius Scipio (appointed 174 BC)
- Lucius Cornelius Merula (late 2nd century BC)
The Julian and Later Periods
The office remained significant through the Republic and into the early Empire. Gaius Julius Caesar was chosen as Flamen Dialis, though his tenure is debated. After a long hiatus, the office was revived.
- Gaius Julius Caesar (chosen late 87 BC)
- Servius Cornelius Lentulus Maluginensis (c. 15 BC)
- Cornelius Lentulus Maluginensis (AD 23)
- Terentius Gentianus (last known holder, consul AD 211)
The removal of some traditional restrictions allowed later holders to pursue political careers, such as consulship.
