To those of us who spend our weekends squinting through loupes at the remnants of the 4th century, there is a distinct shift that occurs when we move from the visionary, solar-inspired coins of Constantine the Great to the more rigid, militaristic issues of his middle son, Flavius Julius Constantius, better known to history as Constantius II. If his father was the architect who designed the new Roman house, Constantius II was the grim-faced guardian who spent twenty-four years patrolling its hallways with a spear, refusing to let the structure collapse under the weight of civil war and heresy.
A Child of the Frontiers
Born on August 7, 317, in the fortress city of Sirmium, Constantius was a child of the barracks. He was named after his grandfather, the “Pale Emperor” Constantius Chlorus, and from his earliest days, his life was a curated public performance. While his father was busy dismantling the last vestiges of the Tetrarchy, young Constantius was being groomed as a Christian prince in a world that still smelled of pagan incense.
In 324 AD, at the tender age of seven, he was raised to the rank of Caesar. For a numismatist, these early coins are charmingly deceptive. They feature a youthful, draped bust with large, soulful eyes, a style often referred to as the “heavenward look,” mimicking his father’s later portraits. Yet, beneath that innocent copper or gold surface lay the steel of a man who would eventually oversee the execution of nearly his entire extended family to secure his grip on the throne.
The Blood-Soaked Succession
When the Great Constantine died in 337 AD, the “Restoration of Happy Times” promised by the imperial mints began with a massacre. To ensure the succession of Constantine’s three sons, the military purged potential rivals, including uncles and cousins. Constantius II inherited the East, a vast, wealthy, and volatile territory encompassing Greece, Asia Minor, Syria, and Egypt.
This era ushered in a fascinating numismatic transition. The silver denarius was a distant memory, replaced by the billon centenionalis and the gold solidus. On the reverses of these coins, we see the first tentative steps into a truly Christian imperial iconography. While the “Unconquered Sun” had finally set, the Chi-Rho, the monogram of Christ, began to appear with more frequency, often tucked into the field of the coin or held aloft by a personification of Victory.
The Spear and the Falling Horseman
The reign of Constantius II was defined by the relentless pressure of the Sassanid Persian Empire under the long-lived Shapur II. Year after year, Constantius had to defend the eastern borders, a struggle that required a massive output from the mints at Antioch and Constantinople to pay the legions.
It was during this time, around 348 AD, that the most iconic coin of the mid-4th century was struck, the “Falling Horseman” type. The reverse legend proudly proclaims FEL TEMP REPARATIO (The Restoration of Happy Times), but the imagery is brutally realistic. It depicts a Roman soldier spearing a barbarian rider who has been unseated from his horse. To a collector, these coins are a window into the state’s psyche. Constantius wasn’t selling a dream of peace, he was selling the reality of survival through military dominance. Every time a merchant in Alexandria or a soldier in Britain handled one of these bronzes, they were reminded that the Emperor’s spear was the only thing standing between them and the “barbarian” chaos.
The Arian Emperor and the Battle of Creeds
Beyond the battlefield, Constantius II was a theological warrior. He was a fervent supporter of Arianism, the branch of Christianity that argued Jesus was subordinate to God the Father. This put him in direct conflict with the Nicene Creed established by his father at the Council of Nicaea.
He didn’t just debate theology, he used the machinery of the state to enforce it. He exiled defiant bishops like Athanasius of Alexandria and convened councils to rewrite the faith in his image. In the coins of this period, we see a move toward a more “standardized” imperial bust. The portraits become less like individual people and more like symbols of the Office of the Emperor, reflecting his view that he was the “Bishop of Bishops,” an autocrat whose word was law in both the forum and the church.
The Final Gambit and the Rise of Julian
After the deaths of his brothers Constantine II and Constans, Constantius II became the sole Augustus of the Roman world. He was a man of three marriages, the most influential being to Eusebia, whose own rare coinage is a prize for any collector, but he lacked a male heir.
In a moment of necessity, he appointed his last surviving cousin, Julian, as Caesar of the West in 355 AD. Julian proved to be a spectacular success, perhaps too much so. When Julian’s troops proclaimed him Augustus in 360 AD, Constantius prepared for one last civil war. He turned his veteran eastern armies back toward the West, ready to crush his cousin as he had crushed so many usurpers before.
However, the “Pale Fever” caught him before the legions could meet. Constantius II died on November 3, 361, in Mopsuestia. On his deathbed, he supposedly named Julian his successor, a final act of cold, administrative logic to prevent the empire from fracturing. He was buried in the Church of the Holy Apostles, the last son of the Great Constantine to hold the world together by sheer, grinding persistence.
