Identification and Purpose of Roman Material Remains

To construct this safely, the architects used concrete with graduated aggregates. They placed heavy travertine at the base, lighter tufa and brick in the middle, and ultralight volcanic pumice at the top. The dome features an oculus (a 9-metre circular opening) at its peak, which provided the only light source and significantly reduced the structural weight. The building's purpose was to honour "all gods" and project the Emperor's universal power. The logistical feat of transporting 60-ton Egyptian granite columns across the Mediterranean physically demonstrated Rome's dominance over its empire.

Located in the Forum Boarium, the Temple of Portunus (god of harbours) offers a different architectural statement. It is a pseudoperipteral structure, meaning it has free-standing columns on its front porch, but only attached half-columns along the side and rear walls of the cella (inner sanctuary). Unlike Greek temples, which have steps on all sides, Roman temples sit on a raised podium with a single frontal staircase. This fusion of Greek aesthetic columns with Etruscan frontal design suited the tight urban spaces of Rome.

Imperial Propaganda: Statues and Monuments

Every time a new emperor took power, they needed to convince the public they deserved to rule. Augustus mastered this through carefully curated iconography.

• Augustus of Prima Porta: Found at the Villa of Livia, this 2.08m marble statue depicts Augustus in an adlocutio (military address) pose. It is sculpted in an idealised, youthful style. The breastplate details a Parthian returning Roman standards, framing diplomacy as military victory. A Cupid riding a dolphin sits at his bare feet, symbolising his divine descent from Venus and his naval triumph at Actium.
• Augustus as Pontifex Maximus: Found near the Via Labicana, this statue shows Augustus holding the title of chief priest. He is depicted capite velato (with his toga pulled over his head), a traditional pose demonstrating pietas (religious devotion). A capsa (document box) sits at his feet. Interestingly, the body uses Italian Luna marble, but the head uses Greek Pentelic marble, suggesting a specialist Greek master carved the portrait.

Analysing Material Choices for Propaganda: The original purpose of a monument directly dictated its materials. Augustus chose newly available Carrara (Luna) marble for the Ara Pacis Augustae (Altar of Peace) in the Campus Martius. This brilliant white stone symbolised a pure "Golden Age" and promoted Roman self-sufficiency, proving Rome no longer relied on Greek imports. Conversely, when Domitian built the Arch of Titus on the Summa Sacra Via to commemorate his brother's victories and subsequent apotheosis (deification), he deliberately imported Pentelic marble from Athens. By using the exact stone of the Parthenon, Domitian elevated his "new" Flavian dynasty to the timeless, divine status of classical antiquity.

Roman Mass Media: Prescribed Coins

Before the internet or television, coins were the only way most citizens ever saw their leader's face. The obverse (heads) typically featured the emperor, while the reverse (tails) broadcasted political messaging.

Coin	Obverse Features	Reverse Messaging & Original Purpose
Aureus of Augustus (2 BC – AD 4)	Laureate head of Augustus, labelled "Father of the Fatherland".	Shows his grandsons Gaius and Lucius resting on shields. Created as dynastic propaganda to establish them as his legitimate successors.
Denarius of Augustus (19 BC)	Bare head of Augustus.	Shows Mars Ultor (Mars the Avenger) inside a circular temple holding a recovered standard. It justified peace with Parthia as a "vengeful" military victory.
Aureus of Claudius (AD 46–47)	Laureate head of Claudius with imperial titles.	Features a triumphal arch reading DE BRITANN. Claudius used this to legitimise his unstable rule by celebrating the conquest of Britain.

City Life: Housing, Spectacle, and Daily Voices

Roman society was strictly divided by wealth, and their architecture reflected this inequality physically.

The wealthy lived in sprawling homes like the House of Menander in Pompeii, which featured a peristyle garden, private baths, and a grand reception hall called an atrium. In contrast, the urban poor in cities like Ostia lived in the Insula of Diana. This was a multi-storey apartment block built from opus latericium (brick-faced concrete). The walls were deliberately built thinner on the upper floors to prevent collapse, and the ground floor contained tabernae (shops).

Public leisure was also a tool for social control. The Colosseum (Flavian Amphitheatre) used 100,000 cubic metres of travertine to house 50,000 spectators. It featured 80 vomitoria (arched exit passages) to manage crowd flow. Games were staged to appease the masses, but seating was strictly segregated: the elite sat at the bottom on marble seats, while the poor sat at the top on wooden benches.

The voices of ordinary Romans survive through graffiti. Inscription CIL IV 5296 from Pompeii is a rare, delicate love poem written by a woman to another woman, lamenting how daylight separates lovers. Other inscriptions, like CIL IV 1679, show tavern patrons complaining about bad service. These scribbles prove that literacy was surprisingly common across different social classes.

The Mechanics of Warfare

Understanding military dominance explains why Rome maintained its borders for centuries. The Roman fortress of Deva Victrix (Chester) was laid out in a strict "playing card" grid. It included horrea (granaries) raised on stilts to keep grain dry, and a headquarters containing a shrine for the legion's eagle standard.

The standard legionary was highly equipped. They wore lorica segmentata (articulated plate armour) and carried a scutum (curved rectangular shield). Their primary throwing weapon was the pilum, a javelin engineered with a thin metal shank. Upon striking an enemy's shield, the shank would bend, making the shield unbearably cumbersome and preventing the enemy from throwing the weapon back.
