The Roman Forum (), also known by its Latin name Forum Romanum, is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the centre of the city of Rome. Citizens of the ancient city referred to this space, originally a marketplace, as the , or simply the .

For centuries, the Forum was the centre of day-to-day life in Rome: the site of triumphal processions and elections; the venue for public speeches, criminal trials and gladiatorial matches; and the nucleus of commercial and legal affairs. Here statues and monuments commemorated the city's leaders. The heart of ancient Rome, it has been called the most celebrated meeting place in the world, and in all history.Grant, Michael (1970), The Roman Forum, London: Weidenfeld & Nicolson; Photos by Werner Forman, p. 11. Located in the small valley between the Palatine and Capitoline Hills, the Forum today is a sprawling ruin of architectural fragments and intermittent archaeological excavations attracting 4.5 million or more sightseers yearly.

Many of the oldest and most important structures of the ancient city were located on or near the Forum. The Roman Kingdom's earliest shrines and temples were located on the southeastern edge. These included the ancient former royal residence, the Regia (8th century BC), and the Temple of Vesta (7th century BC), as well as the surrounding complex of the Vestal Virgins, all of which were rebuilt after the rise of imperial Rome.

Other archaic shrines to the northwest, such as the Umbilicus Urbis and the Vulcanal (Shrine of Vulcan), developed into the Republic's formal Comitium (assembly area). This is where the Senate—as well as Republican government itself—began. The Senate House, government offices, tribunals, temples, memorials and statues gradually cluttered the area.

Over time, the archaic Comitium was replaced by the larger adjacent Forum, and the focus of judicial activity moved to the new Basilica Aemilia (179 BC), formally Basilica Fulvia. Some 130 years later, Julius Caesar built the Basilica Julia, along with the new Curia Julia, refocusing both the judicial offices and the Senate itself. This new Forum, in what proved to be its final form, then served as a revitalized city square where the people of Rome could gather for commercial, political, judicial and religious pursuits in ever greater numbers.

Eventually, much economic and judicial business would transfer away from the to the larger and more extravagant structures (Trajan's Forum and the Basilica Ulpia) to the north. The reign of Constantine the Great saw the construction of the last major expansion of the Forum complex—the Basilica of Maxentius (312 AD). This returned the political centre to the Forum until the fall of the Western Roman Empire almost two centuries later.

Description

Unlike the later imperial fora in Rome—which were self-consciously modelled on the ancient Greek plateia (πλατεῖα) public plaza or town square—the Roman Forum developed gradually, organically, and piecemeal over many centuries., p. 22. This is the case despite attempts, with some success, to impose some order there, by Sulla, Julius Caesar, Augustus and others. By the Imperial period, the large public buildings that crowded around the central square had reduced the open area to a rectangle of about 130 by 50 meters.A more generous estimate, including the surrounding buildings, would be about 200 by 75 meters.

Its long dimension was oriented northwest to southeast and extended from the foot of the Capitoline Hill to that of the Velian Hill. The Forum's basilicas during the Imperial period—the Basilica Aemilia on the north and the Basilica Julia on the south—defined its long sides and its final form. The Forum proper included this square, the buildings facing it and, sometimes, an additional area (the Forum Adjectum) extending southeast as far as the Arch of Titus.Grant, 1970, p. 43.

Originally, the site of the Forum had been a marshy lake where waters from the surrounding hills drained. This was drained by the Tarquins with the Cloaca Maxima. Because of its location, sediments from both the flooding of the Tiber and the erosion of the surrounding hills have been raising the level of the Forum floor for centuries. Excavated sequences of remains of paving show that sediment eroded from the surrounding hills was already raising the level in early Republican times.

As the ground around buildings rose, residents simply paved over the debris that was too much to remove. Its final travertine paving, still visible, dates from the reign of Augustus. Excavations in the 19th century revealed one layer on top of another. The deepest level excavated was 3.60 meters above sea level. Archaeological finds show human activity at that level with the discovery of carbonized wood.

An important function of the Forum, during both Republican and Imperial times, was to serve as the culminating venue for the celebratory military processions known as Triumphs. Victorious generals entered the city by the western Triumphal Gate (Porta Triumphalis) and circumnavigated the Palatine Hill (counterclockwise) before proceeding from the Velian Hill down the Via Sacra and into the Forum.Grant, 1970, p. 16.

From here, they would mount the Capitoline Rise (Clivus Capitolinus) up to the Temple of Jupiter Optimus Maximus on the summit of the Capitol. Lavish public banquets ensued back down on the Forum. (In addition to the Via Sacra, the Forum was accessed by several storied roads and streets, including the Vicus Jugarius, Vicus Tuscus, Argiletum, and Via Nova.)

History

Pre-Roman Period Pottery deposits discovered in the Forum, Palatine and Capitoline demonstrated that humans occupied these areas in the Final Bronze Age (1200–975 BC).Lomas, Kathryn, 2018 (hardcover in 2017), Rise of Rome: From the Iron Age to the Punic Wars, 1000 BC – 264 BC, London: Profile Books, p. 38. In the early Iron Age an area of the future Forum, close to the site of Temple of Antoninus and Faustina, was used as a cemetery (10th century BC), possibly by the communities based on the Palatine and Capitoline hills.Fulminante, Francesca, 2014, The Urbanisation of Rome and Latium Vetus. From the Bronze Age to the Archaic Era, Cambridge: Cambridge University Press, pp. 72–74. Most of the burials were cremations of the same type which is also found in the other sites in Latium. The urn containing the ashes of the deceased was placed inside a large earthenware jar, along with grave goods, and then buried in a cavity cut into the ground and covered with a capstone.Lomas, 2018, p. 39. There were also a small number of inhumation burials. On current evidence, it is likely that burials in the Forum ceased in the late 9th century BC and that the Esquiline Necropolis replaced them.

The first archaeological finds on the sites of the key public buildings point to a transformation of the Forum from a cemetery to a public site in the 8th century BC.Lomas, 2018, pp. 40–42. Part of the Forum was paved over. The earliest finds in the sites of the Comitium and Vulcanal were votive offerings. They indicate that the area was dedicated to a celebration of religious cults.Lomas, 2018, p. 41.

Roman Kingdom

Roman historical tradition

According to Roman historical tradition, the Forum's beginnings are connected with the alliance between Romulus, the first king of Rome controlling the Palatine Hill, and his rival, Titus Tatius, who occupied the Capitoline Hill. An alliance formed after combat had been halted by the prayers and cries of the Sabine women. Because the valley lay between the two settlements, it was the designated place for the two peoples to meet. Since the early Forum area included pools of stagnant water, the most easily accessible area was the northern part of the valley which was designated as the Comitium. It was here at the Vulcanal that, according to the story, the two parties laid down their weapons and formed an alliance.

The Forum was outside the walls of the original Sabine fortress, which was entered through the Porta Saturni. These walls were mostly destroyed when the two hills were joined. The original Forum functioned as an open-air market abutting on the Comitium, but eventually outgrew its day-to-day shopping and marketplace role. As political speeches, civil trials, and other public affairs began to take up more and more space in the Forum, additional fora throughout the city began to emerge to expand on specific needs of the growing population. Fora for cattle, pork, vegetables and wine specialised in their niche products and the associated deities.

Rome's second king, Numa Pompilius (r. 715–673 BC), is said to have begun the cult of Vesta, building its house and temple as well as the Regia as the city's first royal palace. Later Tullus Hostilius (r. 673–642 BC) enclosed the Comitium around the old Etruscan temple where the Senate would meet at the site of the Sabine conflict. He is said to have converted that temple into the Curia Hostilia close to where the Senate originally met in an old Etruscan hut. In 600 BC Tarquinius Priscus had the area paved for the first time.

Archaeological evidence

Originally a low-lying, grassy wetland, the Forum was drained in the 7th century BC with the building of the first structures of Cloaca Maxima, a large covered sewer system that emptied into the Tiber, as more people began to settle between the two hills. Archaeological evidence shows that by the end of the 7th century BC, the ground level of the Forum was raised significantly in some places to overcome the problems of poor drainage and provide a foundation for a pebble-paved area.Ammerman, Albert J., 1990, “On the Origins of the Forum Romanum”, American Journal of Archaeology, Vol. 94, No. 4 (Oct., 1990), p. 627–645.Lomas, 2018, pp. 90–95. In the middle of the 7th century BC thatch-and-timber huts were demolished on the route of the Via Sacra and rectangular stone buildings began to replace them.Wiseman, Timothy Peter, 2008, Unwritten Rome, Exeter: University of Exeter Press, p. 2.

The earliest structures in the Forum were discovered in two separate locations: the site of the Comitium and the group of sanctuaries of Regia (House of the kings), House of the Vestals and Domus Publica. Around 650–630 BC the area of the Comitium was excavated into a deep triangular depression. The area was paved with a beaten earth pavement and later replaced with a more substantial gravel one. Nearby was located an archaic sanctuary dedicated to Vulcan known as Vulcanal (also Volcanal): a small rectangular pit and elliptical basin carved out of an outcrop of tuff.Filippi, Dunia, 2017 (edition in Italian in 2012), 'Region VIII. Forum Romanum Magnum', in Andrea Carandini, Paola Carafa, The Atlas of Ancient Rome. Biography and Portraits of the City. Vol. 1. Text and Images, Princeton and Oxford: Princeton University Press, pp. 151–152.Lomas, 2018, p. 91. It has been suggested that the earliest ancient materials collected in the area of the Vulcanal are from the second half of the 8th century BC.Carafa, Paolo, 2005, ‘Il Volcanal e il Comizio’, Workshop di Archeologia Classica 2, p. 135. It appears that the Romans were aware of the sites’ archaic origins: the foundation of the Comitium and Vulcanal were attributed to Romulus himself while the first Curia (senate house), which was located nearby, to Tullus Hostilius.Dionysius of Halicarnassus, Roman Antiquities, 2.50.2 (attributes the foundation of the Vulcanal to Romulus and Titus Tatius); Varro, On the Latin Language, 5.74 (attributes the institution of the Vulcanal to Titus Tatius alone); Plutarch, Life of Romulus, 19.27.6 (mentions that Romulus was supposedly killed by the senators next to the Vulcanal).
