Augustus transformed Rome from a republic into an empire through sweeping reforms that stabilized the government, expanded territories, and ushered in the Pax Augusta. This period of relative peace and prosperity also produced a cultural renaissance in literature, art, and architecture that defined Roman civilization for centuries.
Augustan Reforms and Pax Augusta
Political and Social Reforms
After decades of civil wars, Augustus set out to restore stability and traditional Roman values. His reforms touched nearly every part of public life.
He revived the censorship office to conduct a census and review the Senate's rolls, trimming its membership from 900 to 600. This gave him tighter control over who held political influence.
To address declining birth rates among the upper classes, he passed marriage and family laws known as the Lex Julia and the Lex Papia Poppaea, which penalized unmarried citizens and rewarded families with multiple children.
Augustus also promoted a religious revival:
- Restored 82 temples across Rome
- Revived ancient festivals and ceremonies, including the Ludi Saeculares in 17 BCE
- Assumed the title of pontifex maximus, making himself the chief priest of Roman state religion and linking political authority directly to religious authority
Pax Augusta and Imperial Expansion
The Pax Augusta (Augustan Peace) refers to the long stretch of relative peace and stability during Augustus' reign (27 BCE–14 CE). Augustus expanded Roman territory through a combination of military conquest and diplomacy:
- Egypt became a Roman province in 30 BCE after the defeat of Mark Antony and Cleopatra
- Roman control expanded across Hispania (Spain), Gaul (France), and parts of Germania, with the Rhine and Danube rivers secured as natural frontiers
- Through diplomacy rather than war, Augustus negotiated the return of Roman military standards lost to the Parthians when Crassus was defeated in 53 BCE. This was a major symbolic victory that he publicized widely
Economic Reforms and Imperial Coinage
Augustus overhauled Rome's finances and public services. He established new taxes, including a 1% sales tax (centesima rerum venalium) and a 5% inheritance tax (vicesima hereditatium) on Roman citizens.
He also regularized the cura annonae, the grain dole that provided free grain to roughly 200,000 of Rome's poorest citizens. To keep the city safe and functional, he created two new forces:
- The vigiles, a firefighting brigade
- The cohortes urbanae, an urban police force
His standardized coinage system used gold (aureus), silver (denarius), and bronze (sestertius) coins stamped with his portrait. These coins did double duty: they facilitated trade across the empire and spread Augustus' image and authority to every province.
Augustan Literature
Golden Age of Latin Literature
The Augustan Age is considered the golden age of Latin literature. The stability of the Pax Augusta and direct patronage from Augustus' inner circle created ideal conditions for writers and poets.
Augustus' close friend and advisor Gaius Maecenas played a central role, financially supporting many of the era's most famous writers, including Virgil, Horace, and Propertius. Augustan literature frequently celebrated traditional Roman values, the greatness of Rome, and Augustus' own achievements.
Epic Poetry: Virgil's Aeneid
Virgil (70–19 BCE) is widely regarded as Rome's greatest epic poet. His masterpiece, the Aeneid, tells the story of Aeneas, a Trojan hero who escapes the fall of Troy, journeys to Italy, and becomes the legendary ancestor of the Romans.
The poem deliberately draws parallels between Aeneas and Augustus, casting both as founders and protectors of Rome and emphasizing the idea that Roman greatness was divinely ordained. Virgil also wrote the Eclogues (pastoral poems about rural life) and the Georgics (a didactic poem about agriculture).
Lyric Poetry: Horace's Odes
Horace (65–8 BCE) was Rome's leading lyric poet, best known for his Odes, Satires, and Epistles. His Odes range across themes of love, friendship, patriotism, and Augustan ideals, and they're admired for their wit, elegance, and skillful adaptation of Greek lyric meters.
Augustus personally commissioned Horace to write the Carmen Saeculare, a hymn performed at the Ludi Saeculares in 17 BCE. This commission shows how closely literature and political power were intertwined during this period.
Historical Writing: Livy's Ab Urbe Condita
Livy (59 BCE–17 CE) was the most prominent historian of the Augustan Age. His massive work Ab Urbe Condita (From the Founding of the City) traced Rome's history from its legendary founding by Romulus in 753 BCE all the way to his own time.
The original work spanned 142 books, though only 35 survive today. Livy wasn't always strictly accurate by modern standards. His real focus was on moral lessons and exemplary behavior, using history to promote traditional Roman virtues and reinforce the idea of Roman greatness.
Augustan Architecture and Art
Augustan Building Program
Augustus launched a massive building program across Rome. He famously boasted, "I found Rome a city of bricks and left it a city of marble."
Major construction projects included:
- The Temple of Apollo on the Palatine Hill
- The Temple of Mars Ultor (Mars the Avenger) in the new Forum Augustum, which also featured statues of great Roman heroes
- Restoration of 82 older temples and structures that had fallen into disrepair
- Public works like the Aqua Virgo aqueduct and the Porticus Octaviae, which served as a public library and art gallery
Ara Pacis: Monument to Augustan Peace
The Ara Pacis Augustae (Altar of Augustan Peace) is one of the most important surviving artworks from this period. Dedicated in 9 BCE, it commemorated Augustus' return from campaigns in Gaul and Hispania and celebrated the peace he had established.
The altar is covered in intricate marble reliefs that include:
- Mythological scenes tied to Rome's founding
- Allegorical figures representing Pax (Peace), Roma, and Tellus (Earth)
- A procession showing the imperial family and Roman dignitaries
These reliefs blend classical Greek artistic style with Roman political messaging. The Ara Pacis is a prime example of how Augustus used art and architecture to promote his image as a bringer of peace and stability.
Portraiture and Propaganda
Augustan art consistently served a political purpose, promoting Augustus' ideals and legitimizing his rule.
The most famous example is the Prima Porta Augustus, an idealized statue depicting him as youthful, powerful, and heroic, even though it was created when he was much older. The statue's cuirass (breastplate) features reliefs showing his diplomatic triumph over the Parthians and his role as peacemaker.
Portraits of Augustus were distributed across the empire in many forms: statues, coins, and carved gemstones. Two notable cameos further reinforced his image:
- The Gemma Augustea, which depicts Augustus enthroned like Jupiter
- The Grand Camée de France, showing the imperial family in a scene that emphasizes divine favor
Together, these works promoted Augustus' near-divine status and established the legitimacy of the Julio-Claudian dynasty that would rule after him.
