The Appian Way, also known by its Latin and Italian name, Via Appia, is one of the earliest and strategically most important Roman roads of the ancient republic. It connected Rome to Brindisi, in southeast Italy. Its importance is indicated by its common name, recorded by Statius, of Appia longarum... regina viarum ('the Appian Way, the queen of the long roads'). The road is named after Appius Claudius Caecus, the Roman censor who, during the Samnite Wars, began and completed the first section as a military road to the south in 312 BC.
In July 2024, the Appian Way entered the UNESCO World Heritage List.
Origins
Development
The Appian Way was a Roman road that the Republic used as a main route for military supplies for its conquest of southern Italy in 312 BC and for improvements in communication.
The Appian Way — essential to the Romans — was the first long road built specifically to transport troops outside the smaller region of greater Rome. The few roads outside the early city were Etruscan and went mainly to Etruria.
The Samnite Wars
Romans had an affinity for the people of Campania, who, like themselves, traced their backgrounds to the Etruscans. The Samnite Wars were instigated by the Samnites when Rome attempted to ally itself with the city of Capua in Campania. The Italic speakers in Latium had long ago been subdued and incorporated into the Roman state. They were responsible for changing Rome from a primarily Etruscan to a primarily Italic state.
Dense populations of sovereign Samnites remained in the mountains north of Capua, which is just north of the Greek city of Neapolis. Around 343 BC, Rome and Capua attempted to form an alliance. The Samnites reacted with military force.
The barrier of the Pontine Marshes
Between Capua and Rome lay the Pontine Marshes (Pomptinae paludes), a swamp infested with malaria. A tortuous coastal road wound between Ostia at the mouth of the Tiber and Neapolis. The Via Latina followed its ancient and scarcely more accessible path along the foothills of Monti Laziali and Monti Lepini, which are visible towering over the former marsh.
In the First Samnite War (343–341 BC) the Romans found they could not support or resupply troops in the field against the Samnites across the marsh. A revolt of the Latin League drained their resources further. They gave up the attempted alliance and settled with Samnium.
Colonization to the southeast
The Romans were only biding their time while they looked for a solution. The first answer was the colonia, a "cultivation" of settlers from Rome, who would maintain a permanent base of operations. The Second Samnite War (327–304 BC) erupted when Rome attempted to place a colony at Cales in 334 BC and again at Fregellae in 328 BC on the other side of the marshes. The Samnites, now a major power after defeating the Greeks of Tarentum, occupied Neapolis to try to ensure its loyalty. The Neapolitans appealed to Rome, which sent an army and expelled the Samnites from Neapolis.
Appius Claudius' beginning of the works
In 312 BC, Appius Claudius Caecus became censor at Rome. He was of the gens Claudia, who were patricians descended from the Sabines taken into the early Roman state. He had been given the name of the founding ancestor of the gens, Appius Claudius (Attus Clausus in Sabine). He was a populist, i.e., an advocate of the common people. A man of discernment and perception, in the years of success he was said to have lost his eyesight and thus acquired the name caecus, 'blind'. In antique literature, blindness was sometimes associated with great vision, cf. Homer.
Without waiting to be told what to do by the Senate, Appius Claudius began bold public works to address the supply problem. An aqueduct (the Aqua Appia) secured the water supply of the city of Rome. By far the best known project was the road, which ran across the Pontine Marshes to the coast northwest of Naples, where it turned north to Capua. On it, any number of fresh troops could be sped to the theatre of operations, and supplies could be moved en masse to Roman bases without hindrance by either enemy or terrain. It is no surprise that, after his term as censor, Appius Claudius became consul twice, subsequently held other offices, and was a respected consultant to the state even during his later years.
Success of the road
The road achieved its purpose. The outcome of the Second Samnite War was at last favorable to Rome. In a series of blows the Romans reversed their fortunes, bringing Etruria to the table in 311 BC, the very year of their revolt, and Samnium in 304 BC. The road was the main factor that allowed them to concentrate their forces with sufficient rapidity and to keep them adequately supplied, whereafter they became a formidable opponent.
Construction
The main part of the Appian Way was started and completed in 312 BC.
The road began as a leveled dirt path on which small stones and mortar were laid. This base was covered with gravel, and finally topped with tightly fitting, interlocking stones to create a flat and durable surface. The historian Procopius remarked that the stones fit together so securely and precisely that they appeared to have grown together rather than been set by hand. The road was cambered in the middle to allow for water runoff and flanked by ditches on either side, which were protected by retaining walls.
Between Rome and Lake Albano
The road began in the Forum Romanum, passed through the Servian Wall at the porta Capena, went through a cutting in the clivus Martis, and left the city. For this stretch of the road, the builders used the Via Latina. The building of the Aurelian Wall centuries later required the placing of another gate, the Porta Appia. Outside of Rome the new Via Appia went through well-to-do suburbs along the Via Norba, the ancient track to the Alban Hills, where Norba was situated. The road at the time was a via glarea, a gravel road. The Romans built a high-quality road, with layers of cemented stone over a layer of small stones, cambered, drainage ditches on either side, low retaining walls on sunken portions, and dirt pathways for sidewalks. The Via Appia is believed to have been the first Roman road to feature the use of lime cement. The materials were volcanic rock. The surface was said to have been so smooth that you could not distinguish the joints. The Roman section still exists and is lined with monuments of all periods, although the cement has eroded out of the joints, leaving a very rough surface.
Across the marsh
The road concedes nothing to the Alban Hills, but goes straight through them over cuts and fills. The gradients are steep. Then it enters the former Pontine Marshes. A stone causeway of about 31 kilometers (19 mi) led across stagnant and foul-smelling pools blocked from the sea by sand dunes. Appius Claudius planned to drain the marsh, taking up earlier attempts, but he failed. The causeway and its bridges subsequently needed constant repair. In 162 BC, Marcus Cornelius Cathegus had a canal constructed along the road to relieve the traffic and provide an alternative when the road was being repaired. Romans preferred using the canal.
Along the coast
The Via Appia picked up the coastal road at Tarracina (Terracina). However, the Romans straightened it somewhat with cuttings, which form cliffs today. From there the road swerved north to Capua, where, for the time being, it ended. The Caudine Forks were not far to the north. The itinerary was Aricia (Ariccia), Tres Tabernae, Forum Appii, Tarracina, Fundi (Fondi), Formiae (Formia), Minturnae (Minturno), Suessa, Casilinum and Capua, but some of these were colonies added after the Samnite Wars. The length of the Appian Way from Rome to Capua was 132 Roman miles (195.4 kilometers (121.4 mi)) and from Capua to Brindisi (244 BC) it was 233 Roman miles (344.8 km; 214.2 mi). The original road had no milestones, as they were not yet in use. A few survive from later times, including a first milestone near the Porta Appia.
Extension to Beneventum
The Third Samnite War (298–290 BC) is perhaps misnamed. It was an all-out attempt by all the neighbors of Rome: Italics, Etruscans and Gauls, to check the power of Rome. The Samnites were the leading people of the conspiracy. Rome dealt the northerners a crushing blow at the Battle of Sentinum in Umbria in 295. The Samnites fought on alone. Rome now placed 13 colonies in Campania and Samnium. It must have been during this time that they extended the Via Appia 35 miles beyond Capua past the Caudine Forks to a place the Samnites called Maloenton, "passage of the flocks". The itinerary added Calatia, Caudium and Beneventum (not yet called that). Here also ended the Via Latina.
Extension to Apulia and Calabria
By 290 BC, the sovereignty of the Samnites had ended. The heel of Italy lay open to the Romans. The dates are somewhat uncertain and there is considerable variation in the sources, but during the Third Samnite War the Romans seem to have extended the road to Venusia, where they placed a colony of 20,000 men. After that they were at Tarentum.
Roman expansion alarmed Tarentum, the leading city of the Greek presence (Magna Graecia) in southern Italy. They hired the mercenary King Pyrrhus of Epirus in neighboring Greece to fight the Romans on their behalf. In 280 BC the Romans suffered a defeat at the hands of Pyrrhus at the Battle of Heraclea on the coast west of Tarentum. The battle was costly for both sides, prompting Pyrrhus to remark "One more such victory and I am lost." Making the best of it, the Roman army turned on Greek Rhegium and effected a massacre of Pyrrhian partisans there.
Rather than pursue them, Pyrrhus went straight for Rome along the Via Appia and then the Via Latina. He knew that if he continued on the Via Appia he could be trapped in the marsh. Wary of such entrapment on the Via Latina also, he withdrew without fighting after encountering opposition at Anagni. Wintering in Campania, he withdrew to Apulia in 279 BC, where, pursued by the Romans, he won a second costly victory at the Battle of Asculum. Withdrawing from Apulia for a Sicilian interlude, he returned to Apulia in 275 BC and started for Campania up the Roman road.
Supplied by that same road, the Romans successfully defended the region against Pyrrhus, crushing his army in a two-day fight at the Battle of Beneventum in 275 BC. The Romans renamed the town from "Maleventum" ("site of bad events") to Beneventum ("site of good events") as a result. Pyrrhus withdrew to Greece, where he died in a street fight in Argos in 272 BC. Tarentum fell to the Romans that same year, who proceeded to consolidate their rule over all of Italy.
The Romans pushed the Via Appia to the port of Brundisium in 264 BC. The itinerary from Beneventum was now Aeculanum, Forum Aemilii, Venusia, Silvium, Tarentum, Uria and Brundisium. The Roman Republic was the government of Italy, for the time being. Appius Claudius died in 273, but in extending the road a number of times, no one has tried to displace his name upon it.
Rediscovery
The Appian Way's path across today's regions Lazio and Campania has always been well known, but the exact position of the part located in Apulia (the original one, not the extension by Trajan) was long unknown, since there were no visible remains of the Appian Way in that region.
In the first half of the 20th century, the professor of ancient Roman topography Giuseppe Lugli managed to discover, with the then-innovative technique of photogrammetry, what probably was the route of the Appian Way from Gravina in Puglia (Silvium) up to Taranto. When analysing aerophotogrammetric shots of the area, Lugli noticed a path (Italian: tratturo) named la Tarantina, whose direction was still largely influenced by the centuriation; this, according to Lugli, was the path of the Appian Way. This path, as well as the part located in today's Apulia region, was still in use in the Middle Ages. A further piece of evidence for Lugli's proposed path is the presence of a number of archaeological remains in that region, among them the ancient settlement of Jesce.
