Casca (series)

Lore & Background

Casca Rufio Longinus is a Roman soldier born around AD 2 in the village of Falerno in the Tuscan hills. After his family dies during a pestilence, he enlists in the 7th Legion at Livorno around AD 21. He later serves with the 10th Legion and, by AD 33, is stationed in Jerusalem, where he is assigned to the execution of Jesus of Nazareth. At Golgotha, Casca pierces Jesus with his spear in an attempt to end his suffering. Jesus condemns Casca to remain as he is until they meet again, leaving Casca unable to die or permanently age. This event establishes the central premise of the series, with Casca condemned to wander through history as an immortal soldier.

Some time later, Casca discovers the nature of his immortality after being stabbed during an altercation with a superior officer. Although he continues to feel pain and can be injured, his wounds heal rapidly and he cannot be killed.

Reader's Guide

The Casca series, created by Barry Sadler in 1979, blends historical fiction with fantasy through the premise of an immortal soldier cursed to wander history. Sadler wrote the original novels until his death in 1989, with The Mongol published posthumously in 1990. Following Sadler's death, the series was continued under his estate through other writers, including Paul Dengelegi and Tony Roberts, who became the principal writer beginning with Halls of Montezuma in 2006. In 2026, John L. Thompson joined Roberts as a co-writer, beginning with The Guardian, the 64th entry in the series. The series has been translated into Swedish and Japanese, with British paperback editions published by Star Books in the mid-1980s. Reception has varied: The Eternal Mercenary achieved strong initial sales, reaching 100,000 copies after approximately one month in bookstores, and was reviewed in Science Fiction Review in 1981 as a fast-paced historical war novel. Later entries by Tony Roberts, such as The Conqueror and The Anzac, received positive reviews from the military history website History of War for their focused plots and historical settings. The series' significance lies in its long-running exploration of an immortal protagonist's encounters with historical events and figures, sustained across decades by multiple authors.

Origins & Core Premise

Barry Sadler, an American writer, launched what would become one of the longest-running historical fantasy series in 1979 with The Eternal Mercenary. The novel introduces Casca Rufio Longinus, a Roman legionary stationed in Jerusalem during the execution of Jesus of Nazareth. At Golgotha, Casca drives his spear into Jesus's side to end his suffering, an act for which Jesus condemns him to remain unchanged until their next meeting. This single event sets Casca on an endless path: he cannot die, cannot permanently age, and is bound to serve as a soldier through every era until the Second Coming. The premise deliberately channels the ancient Longinus legend and the broader Wandering Jew motif, reframing them through the lens of military adventure. The book's commercial success was immediate—Radio & Records reported 100,000 copies sold within roughly a month of its arrival in bookstores, while Sadler himself traveled to Nashville for promotional events. Science-fiction outlets soon took notice, with Mark Willard's 1981 review in Science Fiction Review calling it a fast-paced reworking of the Wandering Jew story and praising Sadler's competent prose despite noting the novel's modest ambitions.

Authorship & Continuity

Barry Sadler personally authored the Casca novels from the series' 1979 inception until his death in 1989. His final work, The Mongol, reached readers posthumously in 1990. After Sadler's passing, the series survived through his estate, which entrusted the character to a succession of new writers. Paul Dengelegi stepped in with The Liberator in 1999 and The Defiant in 2001, bridging the gap before Tony Roberts assumed the principal writer role beginning with Halls of Montezuma in 2006. Roberts went on to produce numerous entries, several of which earned favorable attention from military-history readers. The series reached its sixtieth milestone in 2026, when John L. Thompson joined Roberts as a co-writer on The Guardian, the sixty-fourth installment, followed by The Seeker. Thompson brings a dual role to the franchise: in addition to co-authoring new novels, he has served as the graphic designer responsible for the series' book covers since 2015, giving the ongoing publication a consistent visual identity even as the writing chair shifts between contributors.

Casca's Character & Historical Journey

Casca Rufio Longinus was born around AD 2 in the small village of Falerno, nestled in the Tuscan hills. After a pestilence claimed his family, the young man enlisted in the 7th Legion at Livorno around AD 21, later transferring to the 10th. By AD 33 he found himself in Jerusalem, assigned to the execution detail for Jesus of Nazareth. The spear thrust at Golgotha—meant to end Jesus's suffering—became the curse that defined every subsequent year of Casca's existence. He first recognized his unnatural resilience after a superior officer stabbed him in a dispute; the wound healed, and he could no longer age. Expelled from the legion and condemned to mine slavery, he was eventually sold into the gladiatorial arena, where he concealed his regenerative ability to climb the ranks and earn his freedom. From that point forward, Casca's life became a perpetual military campaign. Arizona State University highlighted in a 2023 feature how the series places him alongside Genghis Khan, Attila the Hun, Marco Polo, Hernán Cortés, Blackbeard, George Washington, Robert E. Lee, and even Adolf Hitler, threading a single fictional soldier through nearly two millennia of real conflict.

Supporting Cast & Antagonists

Beyond Casca himself, the series builds its narrative architecture around two key supporting elements. Julius Goldman, a U.S. Army major serving as a surgeon at the 8th Field Hospital in Nha Trang during the Vietnam War, first encounters the immortal when a severely wounded soldier named Casey Romain begins healing at an impossible rate. Once Goldman recognizes Romain as Casca, he becomes the character's modern confidant and the voice through which Casca's past adventures are recorded. Later entries, such as The Persian, return to Goldman and his former colleague Robert Landries to frame new stories, while Danny Landries—Robert's son—takes on a similar chronicler role in Devil's Horseman. On the antagonistic side, the Brotherhood of the Lamb serves as Casca's recurring enemy across centuries. Governed by an Elder and an Inner Circle of twelve chosen members, the sect clutches the Spear of Longinus as its most sacred relic. A 2012 announcement for a proposed television adaptation underscored how central this centuries-long rivalry is to the franchise's identity.
