Glossary

The vocabulary of Caesar's world — offices, assemblies, military units, and religious terms, each defined as the Romans used them.

Aedile

Magistrate in charge of public games, markets, and the city’s upkeep. Caesar’s lavish aedileship (65 BC) bought him enormous popularity — and enormous debt.

Augur

Priest who interpreted the will of the gods from birds and other signs. No major action — including Caesar’s assassination-day Senate meeting — proceeded without consulting them.

Auctoritas and dignitas

Auctoritas: personal prestige and influence. Dignitas: standing, honor, worth. Caesar named his dignitas as the cause of the civil war — the Senate’s demands, he argued, were an intolerable insult to it.

Client / patron (cliens / patronus)

The web of mutual obligation binding Roman society: patrons protected clients, clients voted and fought for patrons. Caesar’s generosity was patronage at industrial scale.

Commentarii

Literally “notebooks” — unadorned memoranda. Caesar’s title is a pose of modesty: the works are polished political literature pretending to be rough notes.

Consul

The Republic’s highest regular office: two elected annually, holding supreme civil and military authority. Caesar held it in 59 BC — and the consulship’s eclipse under his dictatorship was itself a symbol of the Republic’s end.

Curia

A Senate meeting-house. Caesar was killed in the Curia of Pompey (in the Theatre of Pompey complex), not the Curia Julia — his own new Senate house was still unfinished.

Dictator

A republican emergency office: absolute power for six months to handle a crisis. Sulla and then Caesar stretched it past recognition — Caesar’s dictator perpetuo (dictator for life) made the emergency permanent, which was the point the conspirators could not accept.

Divi filius

“Son of the deified (Julius)” — Octavian’s title after Caesar’s deification in 42 BC. The slogan that turned a teenage heir into a god’s son.

Equites

The equestrian order — wealthy non-senators: businessmen, tax-farmers, officers. A political constituency Caesar cultivated against the senatorial old guard.

Imperator

Originally an acclamation for a victorious general by his troops — not “emperor.” Caesar was hailed imperator repeatedly; the word’s later meaning grew out of his name and his heir’s title.

Ides

The 13th (or, in March, May, July, October, the 15th) of the month. The Ides of March — 15 March 44 BC — became history’s most famous date.

Legion

Rome’s core military unit: ~4,800–5,000 heavy infantry plus auxiliaries. Caesar’s legions — especially the Tenth (Legio X Equestris) — were famously loyal to him personally.

Lupercalia

Ancient fertility festival (15 February). At the Lupercalia of 44 BC, Antony offered Caesar a royal diadem before the crowd; Caesar refused it. The episode fed the kingship rumors.

Novus homo

“New man” — the first of his family to reach the consulship (like Cicero). Caesar, a patrician, was the opposite — but he built his career on popular support against the nobilitas.

Optimates and populares

Not parties but political styles: optimates (“the best men”) defended senatorial privilege; populares used the people’s assemblies against the Senate. Caesar was the most successful popularis in Roman history.

Pontifex maximus

Chief priest of Rome — a hugely prestigious lifetime post Caesar won in 63 BC against senior rivals. It gave him a house on the Via Sacra and a platform for decades.

Praetor

Senior magistrate below the consuls, with judicial and military authority. Caesar was praetor in 62 BC.

Proconsul / propraetor

A former consul or praetor whose command was extended over a province. Caesar governed Gaul as proconsul, 58–50 BC — the legal basis of his army.

Quaestor

The first rung of the senatorial career ladder, handling finances. Caesar was quaestor in 69 BC.

Senate (senatus)

Rome’s council of ex-magistrates — nominally advisory, effectively the government of the Republic. Caesar expanded it (notably with provincials) and then bypassed it; the rump that remained murdered him.

Tribune of the plebs

Magistrates with the power to veto. In January 49 BC Caesar’s tribunes fled Rome to his camp — his public justification for war: the people’s representatives had been violated.

Triumph

The Republic’s supreme military honor: a parade through Rome with spoils, captives, and placards. Caesar celebrated four in one month (46 BC) — Gallic, Egyptian, Pontic, African — plus the Spanish triumph later. The veni vidi vici placard appeared in the Pontic one.
