Basilica Julia

The Lacus Curtius ("Lake Curtius") was a mysterious pit or pool in the ground in the Forum Romanum. The area where the Forum would later be built was originally likely a lake, as the area it was in is known to have been surrounded by brooks and marshes. One part of the area was never drained, but gradually became smaller until only a basin, known as the Lacus Curtius, was left. Its nature and significance in Rome's early history is uncertain, and several conflicting stories exist about its history. The name of the place is likely connected with the Curtia gens, a very old Roman Family with Sabine origins.

The Roman Forum, also known by its Latin name Forum Romanum (Italian: Foro Romano), is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the center of the city of Rome. Citizens of the ancient city referred to this space, originally a marketplace, as the Forum Magnum, or simply the Forum. For centuries the Forum was the center 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 affairs. Here statues and monuments commemorated the city's great men. The teeming heart of ancient Rome, it has been called the most celebrated meeting place in the world, and in all history. 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). 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 Forum Romanum 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 center to the Forum until the fall of the Western Roman Empire almost two centuries later.

The Column of Phocas (Italian: Colonna di Foca) is a Roman monumental column in the Roman Forum of Rome, Italy, built when Rome was part of the Eastern Roman Empire after reconquest from the Kingdom of the Ostrogoths. Erected in front of the Rostra and dedicated or rededicated in honour of the Eastern Roman Emperor Phocas on August 1, 608 AD, it was the last addition made to the Forum Romanum. The fluted Corinthian column stands 13.6 m (44 ft) tall on its cubical white marble socle. On stylistic grounds, the column seems to have been made in the 2nd century for an unknown structure, and then recycled for the present monument. Likewise, the socle was recycled from its original use supporting a statue dedicated to Diocletian; the former inscription was chiselled away to provide a space for the later text. The base of the column was uncovered in 1813, and the inscription on it reads, in Latin: Optimo clementiss[imo piissi]moque / principi domino n[ostro] / F[ocae imperat]ori / perpetuo a d[e]o coronato, [t]riumphatori / semper Augusto / Smaragdus ex praepos[ito] sacri palatii / ac patricius et exarchus Italiae / devotus eius clementiae / pro innumerabilibus pietatis eius beneficiis et pro quiete / procurata Ital[iae] ac conservata libertate / hanc sta(tuam maiesta)tis eius / auri splend(ore fulge)ntem huic / sublimi colu(m)na(e ad) perennem / ipsius gloriam imposuit ac dedicavit / die prima mensis Augusti, indict[ione] und[icesima] / p[ost] c[onsulatum] pietatis eius anno quinto The English translation is as follows: To the best, most clement and pious ruler, our lord Phocas the perpetual emperor, crowned by God, the forever august triumphator, did Smaragdus, former praepositus sacri palatii and patricius and Exarch of Italy, devoted to His Clemency for the innumerable benefactions of His Piousness and for the peace acquired for Italy and its freedom preserved, this statue of His Majesty, blinking from the splendor of gold here on this tallest column for his eternal glory erect and dedicate, on the first day of the month of August, in the eleventh indiction in the fifth year after the consulate of His Piousness. The precise occasion for this signal honour is unknown, though Phocas had formally donated the Pantheon to Pope Boniface IV, who rededicated it to all the martyrs and Mary (Sancta Maria ad Martyres). Atop the column's capital was erected by Smaragdus, the Exarch of Ravenna, a "dazzling" gilded statue of Phocas (which probably only briefly stood there). Rather than a demonstration to mark papal gratitude as it is sometimes casually declared to be, the gilded statue on its column was more likely an emblem of the imperial sovereignty over Rome, which was rapidly fading under pressure from the Lombards, and a personal mark of gratitude from Smaragdus, who had been recalled by Phocas from a long exile and was indebted to the Emperor for retrieving his position of power at Ravenna. In October 610, Phocas was overthrown and killed; his statues everywhere were overthrown. The monument remains today in its original location (in situ). Its isolated, free-standing position among the ruins has always made it a landmark in the Forum, and it often appears in vedute and engravings. The rise in ground level due to silt and debris had completely buried the socle by the time Giuseppe Vasi and Giambattista Piranesi made engravings and etchings of the column in the mid-18th century. The square foundation of brick (illustration, right) was not originally visible, the present level of the Forum not having been excavated down to its earlier Augustan paving until the 19th century.

The Lapis Niger (Latin, "Black Stone") is an ancient shrine in the Roman Forum. Together with the associated Vulcanal (a sanctuary to Vulcan) it constitutes the only surviving remnants of the old Comitium, an early assembly area that preceded the Forum and is thought to derive from an archaic cult site of the 7th or 8th century BC. The black marble paving (1st century BC) and modern concrete enclosure (early 20th century) of the Lapis Niger overlie an ancient altar and a stone block with one of the earliest known Old Latin inscriptions (c. 570–550 BC). The superstructure monument and shrine may have been built by Julius Caesar during his reorganization of the Forum and Comitium space. Alternatively, this may have been done a generation earlier by Sulla during one of his construction projects around the Curia Hostilia. The site was rediscovered and excavated from 1899 to 1905 by Italian archaeologist Giacomo Boni. Mentioned in many ancient descriptions of the Forum dating back to the Roman Republic and the early days of the Roman Empire, the significance of the Lapis Niger shrine was obscure and mysterious to later Romans, but it was always discussed as a place of great sacredness and significance. It is constructed on top of a sacred spot consisting of much older artifacts found about 5 ft (1.5 m) below the present ground level. The name "black stone" may have originally referred to the black stone block (one of the earliest known Latin inscriptions) or it may refer to the later black marble paving at the surface. Located in the Comitium in front of the Curia Julia, this structure survived for centuries due to a combination of reverential treatment and overbuilding during the era of the early Roman Empire.

The Temple of Divus Augustus was a major temple originally built to commemorate the deified first Roman emperor, Augustus. It was built between the Palatine and Capitoline Hills, behind the Basilica Julia, on the site of the house that Augustus had inhabited before he entered public life in the mid-1st century BC. It is known from Roman coinage that the temple was originally built to an Ionic hexastyle design. However, its size, physical proportions and exact site are unknown. Provincial temples of Augustus, such as the much smaller Temple of Augustus in Pula, now in Croatia, had already been constructed during his lifetime. Probably because of popular resistance to the notion, he was not officially deified in Rome until after his death, when a temple at Nola in Campania, where he died, seems to have been begun. Subsequently, temples were dedicated to him all over the Roman Empire.

The Plutei of Trajan (Latin Plutei Traiani; often called the Anaglypha Traiani) are carved stone balustrades built for the Roman emperor Trajan. They are on display inside the Curia Julia in the Forum Romanum today, but are not part of the original structure. It is unknown exactly where Trajan erected them. They are believed to have been built either on the edge of the Rostra or on the sides of the black pavement marking the underground "Tomb of Romulus". In spite of this uncertainty, they are of great historical value because the carvings show the full length of both sides of the Forum at the time they were erected.

The rostra (Italian: Rostri) was a large platform built in the city of Rome that stood during the republican and imperial periods. Speakers would stand on the rostra and face the north side of the comitium towards the senate house and deliver orations to those assembled in between. It is often referred to as a suggestus or tribunal, the first form of which dates back to the Roman Kingdom, the Vulcanal.It derives its name from the six rostra (plural of rostrum, a warship's ram) which were captured following the victory which ended the Latin War in the Battle of Antium in 338 BC and mounted to its side. Originally, the term meant a single structure located within the Comitium space near the Forum and usually associated with the Senate Curia. It began to be referred to as the Rostra Vetera ("Elder Rostra") in the imperial age to distinguish it from other later platforms designed for similar purposes which took the name "Rostra" along with its builder's name or the person it honored.

The Five-Columns monument is a dedicatory addition to the Rostra in the Roman Forum dating to the early fourth century CE. This monument was part of the Tetrarchy’s expansion of the Forum and is connected to the tenth anniversary of the Caesares within the four-ruler system. It is also referred to as the Fünfsäulendenkmal as well as the four-column monument, depending on Jupiter’s inclusion.

The Arch of Septimius Severus (Italian: Arco di Settimio Severo) at the northeastern end of the Roman Forum is a white marble triumphal arch dedicated in 203 A.D. to commemorate the Parthian victories of Emperor Septimius Severus and his two sons, Caracalla and Geta, in the two campaigns against the Parthians of 194-195 A.D. and 197–199 A.D. After the death of Septimius Severus, his sons Caracalla and Geta were initially joint emperors. Caracalla had Geta assassinated in 212 A.D.; Geta's memorials were destroyed and all images or mentions of him were removed from public buildings and monuments. Accordingly, Geta's image and inscriptions referring to him were removed from the arch.

The Comitium (Italian: Comizio) was the original open-air public meeting space of Ancient Rome, and had major religious and prophetic significance. The name comes from the Latin word for "assembly". The Comitium location at the northwest corner of the Roman Forum was later lost in the city's growth and development, but was rediscovered and excavated by archaeologists at the turn of the twentieth century. Some of Rome's earliest monuments; including the speaking platform known as the Rostra, the Columna Maenia, the Graecostasis and the Tabula Valeria were part of or associated with the Comitium. The Comitium was the location for much of the political and judicial activity of Rome. It was the meeting place of the Curiate Assembly, the earliest Popular assembly of organised voting divisions of the Republic. Later, during the Roman Republic, the Tribal Assembly and Plebeian Assembly met there. The Comitium was in front of the meeting house of the Roman Senate – the still-existing Curia Julia and its predecessor, the Curia Hostilia. The Curia Julia is associated with the Comitium by both Livy and Cicero.Most Roman cities had a similar comitium for public meetings (L. contiones) or assemblies for election], councils and tribunals. As part of the forum, where temples, commerce, judicial, and city buildings were located, the comitium was the center of political activity. Romans tended to organize their needs into specific locations within the city. As the city grew, the larger Comitia Centuriata met on the Campus Martius, outside the city walls. The comitium remained of importance for formal elections of some magistrates; however, as their importance decayed after the end of the republic, so did the importance of the comitium.

The Umbilicus Urbis Romae (Classical Latin: [ʊmbɪˈliːkʊs ˈʊrbɪs ˈroːmae̯])—"Navel of the City of Rome"—was the symbolic centre of the city from which, and to which, all distances in Ancient Rome were measured. It was situated in the Roman Forum where its remnants can still be seen. These remains are located beside the Arch of Septimius Severus and the Vulcanal, behind the Rostra. Originally covered in marble, the Umbilicus is now a forlorn-looking brick core some 2 metres high and 4.45 metres in diameter.

The Shrine of Vulcan (Italian: Volcanale), or Vulcanal, or Volcanal, was an 8th-century BC sacred precinct on the future site of the Roman Forum in Rome, modern Italy. Dedicated to Vulcan, the Roman god of fire, it was traditionally considered to commemorate the spot where the legendary figures Romulus and Tatius concluded the peace treaty between the tribes known as the Latins — on the Palatine Hill — and the Sabines — on the Quirinal and Esquiline. This famous merger of the hill-villages was said to be the foundation of the Roman state.
