Under Cæsars' Shadow — Inside the Classic

A Preacher's Cadence

Colby's sentences often build toward a judgment. In the Caligula excerpt, he lists the emperor's achievements—completing the temple, enlarging the palace, erecting the obelisk—then pivots with "But Caligula was so jealous..." The but signals a shift from neutral record to indictment. This pattern recurs: a paragraph on Caligula's extravagant banquets ("brains of peacocks and the tongues of nightingales") is followed by one on his cruelty ("he seemed to delight in causing suffering"). The effect is a seesaw between the impressive and the repulsive, forcing the reader to oscillate between admiration and disgust. Colby rarely lets a fact stand without a moral gloss; even the obelisk's current location near St. Peter's is noted with a parenthetical "not very far, indeed, from the locality where he placed it," a quiet nod to historical continuity that feels almost like a stage direction.

The Emperor as Character

Colby shapes each emperor as a distinct personality through selective detail. For Caligula, he emphasizes physical grotesquerie: a "face was ghastly pale with a look of insanity," "ill-shaped head," "legs thin and his feet misshapen." This description, attributed to Seneca, is paired with Caligula's own dismissal of Seneca's writings as "sand without lime." The exchange turns the biography into a duel of wits. Colby also uses anecdotes to dramatize character: Caligula forbids Virgil and Livy, threatens to abolish laws, and nearly executes Seneca until a whisper saves him. These vignettes compress complex reigns into memorable scenes. The pacing is brisk—each chapter covers a life in roughly twenty pages—but Colby lingers on moments that reveal moral failure, such as Caligula's destruction of Augustus's statues, which he describes with a specificity ("broken that the names could not be restored") that underscores petty malice.

Pacing Between the Lines

The book's rhythm is not uniform. The Augustus chapter, as the first and longest, likely sets a stately pace; the Caligula chapter, by contrast, accelerates into a cascade of vices. Colby uses lists to quicken tempo: "stones, sword, fire, and Caius" (from Seneca) or "the brains of peacocks and the tongues of nightingales and flamingoes." These catalogs create a breathless effect, as if the author is overwhelmed by the emperor's excesses. Yet he also inserts slower, reflective passages, such as the note that Seneca "withdrew into obscurity for the rest of the reign of Caius and devoted himself to his studies and meditations." This pause offers relief from the frenzy. The overall pacing thus mirrors the moral arc: calm exposition, then a rush of depravity, then a quiet aftermath. The excerpts do not reveal whether this pattern holds for Tiberius, Claudius, and Nero, but the Caligula chapter suggests a deliberate alternation between accumulation and reflection.

Readers approaching Under Cæsars' Shadow should attend to Colby's rhetorical shifts—the moments when he steps back from chronicle to commentary. His voice is that of a moralist who believes character shapes history, and his prose gains force from this conviction. The genealogical chart at the start is worth consulting: it maps the familial entanglements that Colby assumes his audience knows. For those unfamiliar with the Julio-Claudian dynasty, the book may feel dense; for others, its brisk judgments and vivid anecdotes offer a portrait gallery painted in strong, opinionated strokes.

There’s something about Colby’s pacing, the way he lets Nero’s ruin unfold slowly, that reminds me of reading about Germany’s long, troubled becoming—not as lessons, but as quiet witnesses to how power wears down a people. I found myself tracing that same shadow in The Evolution of an Empire: A Brief Historical Sketch of Germany — Themes and Context, and it lingers differently than I expected.
