Arbiter Elegantiarum

Arbiter Elegantiarum is the title associated with Petronius as Rome’s judge of elegance. It signifies more than social polish: his command of taste gives him influence at Nero’s court, but that distinction also provokes the emperor’s vanity and marks the limits of Petronius’s safety under imperial power.

Meaning and Courtly Standing

The title identifies Petronius as an unusually authoritative judge of style and artistic merit. In his rivalry with Tigellinus, it becomes politically charged: Nero is irritated by the honor because he considers himself the proper arbiter, while Tigellinus recognizes that he cannot equal Petronius in polish, wit, or learning. Instead of competing on those terms, Tigellinus seeks to secure favor through lavish service and spectacle.

Petronius’s authority is not simply a matter of ceremonial reputation. When Nero reads a new book of the Troyad, the emperor watches Petronius’s face for a genuine response. Petronius listens closely, praises or criticizes, and suggests corrections; Nero gradually turns to him for discussion because Petronius appears to judge the poetry on its merits rather than flatter the ruler. The title therefore names an expertise that can still command attention inside the court, even when the emperor resents the independence that comes with it.

Public Recognition

The title also travels beyond the palace. During the unrest after the fire, Petronius rides into a hostile crowd, whose members recognize him and call out, “Petronius! Arbiter Elegantiarum! Petronius! Petronius!” Their response changes the mood: the crowd’s faces become less threatening and the uproar less savage. Petronius’s standing with the people rests partly on his reputation for humanity, strengthened by his opposition to the collective death sentence imposed on the slaves of Pedanius Secundus. The designation thus carries a public meaning as well as a courtly one: the crowd recognizes in the celebrated judge of taste a figure it considers humane.

At Nero’s gathering, Tigellinus uses the title pointedly when greeting Petronius and asking whether he still denies that the Christians burned Rome. Petronius answers with a remark about Tigellinus’s inability to offer a worthwhile opinion on Nero’s poetry. The exchange makes aesthetic judgment a form of political contest: Tigellinus invokes Petronius’s status, while Petronius’s reply exposes the gap between courtly flattery and informed criticism.

Irony and Final Use

Petronius’s own reflections complicate the prestige of the title. He argues that even powerful wrongdoing tries to preserve the appearance of truth, justice, and virtue, calling that effort an involuntary homage to virtue. He then turns the argument into self-mockery, presenting himself as virtue incarnate because his action toward Lygia can be made to seem beautiful. The speech shows how aesthetic language can sharpen insight while also serving as a self-serving excuse.

At the end, Petronius reads aloud a letter of farewell to Nero. It mocks the emperor’s crimes and, more particularly, his poetry, music, and public performances; Petronius says these have become intolerable to him and closes by identifying himself as “the—Arbiter Elegantiæ.” The title that once expressed standing at court becomes the signature of his final judgment on the ruler. Its irony is complete: Nero possesses imperial power, but Petronius claims the last word on whether that power has taste.
