In this episode of NPR's Book of the Day, Scott Simon speaks with author Robert Harris about his new historical novel centered on Marcus Agrippa, a powerful yet historically obscure figure in ancient Rome. Harris explores Agrippa's remarkable rise from plebeian origins to become Augustus's closest ally, three-time consul, military commander, and master engineer—despite leaving virtually no personal letters or speeches behind. This absence of personal documentation makes Agrippa an ideal subject for historical fiction, offering creative freedom while maintaining historical authenticity.
The conversation extends beyond Agrippa's story to examine why ancient Rome continues to captivate modern audiences. Harris and Simon discuss Rome's influence on Western civilization, particularly its impact on America's founding principles, and explore parallels between the Roman Republic's collapse into autocracy and contemporary political dynamics. Harris observes how modern political figures employ imagery reminiscent of Roman emperors, creating renewed interest in understanding Rome's enduring lessons about power, democracy, and governance.

Agrippa's name comes from "Agrippartum," marking his difficult birth in which his mother died. This tragic origin seems to have shaped his combative identity—he's depicted as brooding, strong, and wary, like a fighter who learned early to defend himself. Despite his plebeian origins, Agrippa was enrolled at around age 13 or 14 in a prestigious Palatine Hill school reserved for senators' sons. There, he met Octavius, Julius Caesar's great-nephew and eventual adopted son, forming a pivotal friendship that would shape both their lives and Rome's future.
After Caesar's victory at Munda, both young men were transported on Caesar's flagship to Apollonia to prepare for an Eastern campaign—a clear sign of special favor. Their bond was strengthened by contrasting qualities: Octavius was sickly and slight, while Agrippa was physically imposing, often serving as his friend's protector. Caesar's assassination in 44 BC halted their rise but opened new political opportunities as they navigated the turbulent aftermath.
Agrippa's talents propelled him to serve as consul three times and to become the effective co-ruler of Rome alongside Augustus. His military genius secured crucial victories strengthening Augustus's regime, while his engineering feats included Rome's aqueducts and the Pantheon, which still bears his name. Speculation suggests Agrippa may have been Caesar's illegitimate son—Caesar was in Rome the year before Agrippa's birth and was notorious for affairs. This theory could explain Agrippa's elite school admission alongside Caesar's closest male relative, his remarkable talents, and the deliberate suppression of biographical details about his early life.
Despite Agrippa's enormous influence as a three-time consul, co-ruler, brilliant general, and master builder, he remains mysteriously anonymous in historical records. He left no letters or speeches, and few of his remarks are documented. For a historical novelist, this scarcity of personal documentation offers remarkable creative freedom. Agrippa appears in other Roman narratives—as the aqueduct builder in "Pompeii" and as Octavius's menacing consigliere in the Cicero trilogy—providing sufficient historical context while leaving his motivations and inner life open to interpretation.
Scott Simon and Robert Harris explore why ancient Rome continues to captivate modern audiences, even becoming a cultural meme. This fascination stems from Rome's profound influence on Western civilization and its resonances with modern leadership and democracy.
Harris highlights Rome's epic achievements in poetry, oratory, philosophy, and architecture as unparalleled accomplishments that continue to inspire. He notes that America's Founding Fathers deliberately drew upon Roman Republican principles when designing the U.S. Constitution, embedding ideas like separation of powers and checks and balances. Harris asserts that Rome is "the foundation of our modern Western world," with Roman influence embedded in Western cultural DNA.
Harris's novel spans the fifty-year collapse of Rome's Republic into oligarchic rule and imperial autocracy. He describes this as a "standing warning" for modern societies, demonstrating democracy's susceptibility to decay. Harris cautions that vigilance and protection of democratic norms are crucial, as no system is immune to fragility.
Harris observes how modern leaders adopt tactics reminiscent of Roman emperors. He notes President Trump's use of triumphal arches, gladiator-style spectacles, and monumental buildings emblazoned with his name—all evoking the theatrical grandeur of Rome's rulers. These parallels between contemporary politics and Roman imperial practices spark renewed fascination with ancient Rome, inviting society to reflect on the enduring legacies of power, spectacle, and statecraft.
1-Page Summary
Agrippa’s name is a shortened form of “Agrippartum,” reflecting his difficult birth. His mother died delivering him, marking the origin of his unusual name. This legacy seems to have imprinted itself on his character, conditioning him from an early age to defend himself. In descriptions and artistic depictions, Agrippa carries the look of a fighter—brooding, strong, wary—much like a heavyweight boxer or nightclub bouncer. The taunts and adversity stemming from his humble beginnings and tragic birth likely instilled a combative streak that would serve him throughout his life.
Despite being born into a plebeian family with little money or social standing, Agrippa was sent at the age of about 13 or 14 to a prestigious school on the Palatine Hill reserved for the sons of senators and Rome’s elite. The exact reason for this remarkable access is unclear, but it positioned Agrippa in the heart of Rome’s power structure.
At this elite school, Agrippa met Octavius, the great-nephew and eventual adopted son of Julius Caesar. This relationship was pivotal, as the two became close friends—an alliance that would shape both their lives and the fate of Rome.
After Caesar’s victory at the Battle of Munda, both Agrippa and Octavius were brought back to Rome on Caesar’s flagship, a sign of special favor. They were then sent together to Apollonia, in modern Albania, to await Caesar for a planned campaign in the East. Both young men had come under Julius Caesar’s wing, marking the start of their entwined political paths.
Their bond was strengthened by their contrasting qualities. Octavius was sickly, slight, and needed built-up shoes for his stature; Agrippa, on the other hand, was physically imposing and often acted as a protector or bodyguard for his friend.
Julius Caesar’s assassination in 44 BC halted his plans, but for Agrippa and Octavius, it opened the way to new political opportunities as they navigated the tumultuous aftermath of Caesar’s death.
Agrippa’s talents propelled him to the height of Roman power. He served as consul three times, and for much of his career was the effective co-ruler of the Roman world alongside Augustus (Octavius).
Agrippa's Rise: From Plebeian to Augustus' Ally and Powerful Roman Figure
Marcus Agrippa holds a unique position in world history as an immensely powerful and important figure. He was consul three times, an effective co-ruler of the Roman world, and a brilliant general who played a significant role in shaping the Roman Empire. As a master builder, Agrippa’s works included not only vital aqueducts but also the Pantheon in Rome, which to this day bears his name above the entrance.
Yet, despite this enormous influence, Agrippa remains shrouded in mystery. He left no letters or speeches, and very few of his remarks are reported in historical sources. This absence of personal documentation stands in stark contrast to his achievements and impact. The records about him are almost anonymous, creating a notable gap that invites speculative exploration.
For a historical novelist, Agrippa is an ideal subject precisely because so little is concretely known about his personal life and inner thoughts. Without the constraints of extensive personal documentation, a novelist gains significant creative freedom to craft a compelling narrative about his life.
Agrippa does appear in other Roman historical narratives, which provide suffi ...
Why Agrippa Is Ideal for Historical Fiction: His Importance & Scarcity of Records
Scott Simon and Robert Harris reflect on why so many remain enthralled by ancient Rome, a fascination that has permeated culture to the extent that it has become a meme—especially among men who reportedly think about Rome frequently. This obsession is rooted in Rome’s profound and lasting influence on Western civilization, its political legacy, and its resonances with modern leadership and democracy.
Robert Harris highlights the epic scale of Roman achievements, citing their poetry, oratory, philosophy, architecture, and military prowess as unparalleled accomplishments that continue to inspire admiration. These cultural and intellectual riches form a bedrock for Western art, learning, and civic life.
Harris notes that America's Founding Fathers deliberately drew upon the Roman Republic when designing the U.S. Constitution. Principles ranging from the separation of powers to checks and balances echo Roman governance, embedding Roman republican ideals in the foundation of American democracy.
According to Harris, Rome is "the foundation of our modern Western world." He asserts that Roman influence is embedded in Western cultural DNA, reflecting back modern values and systems and offering a mirror to contemporary society.
Harris’s novel spans the fifty-year period that saw Rome’s Republic crumble, replaced by oligarchic rule and imperial autocracy. He describes this collapse as a "standing warning" for modern societies, demonstrating democracy’s susceptibility to decay and subversion.
Harris cautions that although history cannot be overdrawn for direct parallels, the narrative of Rome’s gradual decline holds clear lessons for contemporary democracies: vigilance and the protection of democratic norms are crucial, as no system is immune to fragility or the ambitions of a few.
