Roman circus

• 1. Introduction

  ›

  The Roman circus was a place where an entire civilization gathered to feel at home. Writing at the start of the 5th century AD, the historian Edward Gibbon recorded that the Roman people still considered the Circus as their home, their temple, and the seat of the republic. That was a remarkable thing to say about a racetrack. How did a long oval of packed dirt and timber become the symbolic heart of Roman public life? And what exactly went on inside these enormous structures that dotted the empire from Britain to Lebanon to Libya?

  The word circus itself comes from the Latin for circle, though the venues were anything but round. They were vast, elongated rectangles, engineered for spectacle at a scale that most modern sports arenas cannot match. The largest of them, the Circus Maximus in Rome, stretched roughly 621 metres in length and could seat somewhere between 150,000 and 250,000 people. That is a crowd comparable to a modern city. And the Circus Maximus was not the only one. By a count dated to 2012, at least 63 Roman circuses have been identified across three continents.

• 2. The Track and Its Parts

  ›

  At the centre of every circus ran a raised median strip called the spina. This was not merely a divider. It was decorated with ornate columns, statues, and commemorative obelisks, turning the middle of a racetrack into an open-air gallery of Roman civic pride. At each end of the spina, conical poles called metae marked the turning points where chariots swung around at full speed.

  The track itself was shaped by the demands of the race. Two long straight sections ran parallel, separated by the spina along roughly two thirds of the circuit's length. One end curved into a semicircle; the other terminated at the carceres, the starting gates. The carceres were not a straight wall but a distinctive, slightly curved, slanted structure. The angle was deliberate. It compensated for the fact that starting positions farther from the inside of the track would otherwise cover more distance before reaching the first straight. Races ran anticlockwise around the spina.

  Seating climbed upward along both long sides and around the curved end, broken occasionally by access passages and viewing platforms for dignitaries. One circus at Antinoöpolis in Egypt shows a striking gap of around 50 metres between the carceres and the first row of ascending seating, a feature that appears to have no parallel elsewhere among the known sites.

• 3. Scale and Variation

  ›

  Track lengths across the known circuses vary considerably, from around 245 metres at Gerasa in modern Jordan to the 621-metre expanse of the Circus Maximus in Italy. Seating capacity follows a similarly wide range. Gerasa could hold roughly 15,000 spectators. The Circus Maximus, depending on the estimate, held between 150,000 and 250,000.

  Measuring that seating is harder than measuring the track. Track length can be confirmed with small excavations at either end of the centreline, even when the rest of the circus lies buried under later construction. Seating capacity requires knowing the original height and angle of the inclined stands, and in many cases that evidence has been lost or destroyed. So the figures scholars cite vary, and for good reason.

  Not every circus followed the standard rectangular plan. The circus at Emerita Augusta in Mérida, Spain, replaced the flat carceres end with a slightly curved finish, its straight sides joining to rounded corners of ascending seating. A small number of circuses went further and curved both ends into an oval. The examples at Nicopolis in Greece and Aphrodisias in Turkey fall into this category, and the source notes they are typically small enough that they are better understood as stadia rather than true circuses.

  Orientation also varied freely. Circuses across the empire point in every direction of the compass: north at Gerasa, northeast at Antinoöpolis, east at the Circus of Maxentius and at Colchester, southeast at the Circus Maximus, south at Tyrus in Lebanon, southwest at Gortyn in Greece, and west at the Circus of Nero in Rome.

• 4. Deep Roots, Long Construction

  ›

  The Circus Maximus may have existed in some form from as early as around 500 BC, though it would not have resembled what we picture today. Many circuses began as nothing more than a cleared track in open ground. Wooden seating structures followed, and those burned down or rotted away and were rebuilt across multiple generations. Stone construction came last, and it came slowly. The main period of circus construction ran from around 200 BC to 200 AD, roughly four centuries during which the empire's appetite for chariot racing drove a wave of building across its territories.

  The form of the carceres seems to have been standardised empire-wide. The close resemblance among starting gates at circuses of very different sizes suggests builders were working from a shared set of proportional formulas, though when that standardisation began and whether any written records of those formulas survive is not known. Some of the clearest surviving examples of carceres stand at Gerasa in Jordan and the Circus of Maxentius just outside Rome.

  The Circus of Nero, also known as the Circus of Caligula or the Vatican Circus, is one of the more historically charged sites in the list. Its location just south of what is now St. Peter's Basilica is well established, though the exact boundaries and orientation remain uncertain. The one surviving element from its spina is an obelisk brought from Egypt in 37 AD. That obelisk was relocated to Saint Peter's Square in 1586, where it still stands today.

  The only known chariot-racing track in Britain was discovered in 2004 by Colchester Archaeological Trust at Colchester, the Roman Camulodunum. The track ran roughly 450 metres long and 75 metres wide, with evidence of eight starting gates and a central archway at the western end. A spina about 239 metres long divided the arena, and tiered seating stands ringed the circuit with passages through them for spectator access.

  In Jordan, the circus at Gerasa survives well enough to be among the better-documented examples, with much of its structure still standing and no modern buildings occupying the track. In Lebanon, the Tyre hippodrome preserves a clearly visible U-shaped form with a track of around 435 metres and about 80 metres in width, likewise free of later construction. In Libya, the circus at Leptis Magna sits parallel to the sea, its track running around 445 metres, about 1.5 kilometres outside the ancient city walls.

  Some circuses are now buried entirely under functioning towns. The circus at Córdoba in Spain lies completely beneath the existing city centre, with virtually no remains visible above ground. At Sirmium in modern Serbia, the structure lies buried 2 to 4 metres beneath the current town, with only very small sections ever excavated. In Lisbon, excavations beneath what is now the Rossio square uncovered a section of the spina.

  The Hippodrome of Constantinople, built under Septimius Severus, is estimated to have been around 450 metres long and 130 metres wide. Today, aside from a few monuments that once stood on the spina, the structure is almost entirely invisible. Much of it is thought to lie buried about 2 metres beneath the present ground surface.

• 6. What Survived

  ›

  The best-preserved examples of Roman circuses are spread across six countries. The source identifies Emerita Augusta in Spain, Caesarea Maritima on the Israeli coast, the Circus of Maxentius in Italy, Gerasa in Jordan, Tyrus in Lebanon, and Leptis Magna in Libya as standing in the best condition among the known sites.

  The circus at Aphrodisias in Turkey is double U-shaped, substantially preserved, and notably smaller than most other circuses. At around 220 metres long and 35 metres wide, it sits closer in scale to a stadium than to the great racing venues of Rome or Carthage. The circus at Carthage itself ran around 500 metres in length and 90 metres in width, though little of it remains visible and parts have been built over by modern construction.

  In France, the only surviving element of the circus at Vienna is a monumental arched structure topped by a tall, narrow pyramid, which once stood on the spina. At Bovillae near Rome, three stone arches belonging to the carceres are the sole visible remains of a track that measured 328.5 metres long. These fragments, spread across decades and continents of research, are what scholars use to reconstruct a picture of an institution that was once as central to Roman life as Gibbon described it: a place that an empire called home.
