Comitium

The Graecostasis was a platform in the Comitium near the Roman Forum, located to the west of the Rostra. The name refers to the Greek ambassadors for whom the platform was originally built after the Roman Republic conquered Greece. Placed at the southwest end of the Comitium, the platform was the designated spot for all representatives of foreign nations and dignitaries from the republic and empire's domain. Visiting outsiders were not permitted within the Senate House or Curia and instead may have stood on this platform while waiting to meet with senators or to hear orations from the Rostra to its east side. Although one scholar has disputed this interpretation and argues that it may have served as a viewing platform for entertainment.

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 Curia Hostilia was one of the original senate houses or "curiae" of the Roman Republic. It was believed to have begun as a temple where the warring tribes laid down their arms during the reign of Romulus (r. c. 771–717 BC). During the early monarchy, the temple was used by senators acting as a council to the king. Tullus Hostilius (r. 673–641 BC) was believed to have replaced the original structure after fire destroyed the converted temple. It may have held historic significance as the location of an Etruscan mundus and altar. The Lapis Niger, a series of large black marble slabs, was placed over the altar (known as the Volcanal) where a series of monuments was found opposite the Rostra. This curia was enlarged in 80 BC by Lucius Cornelius Sulla during his renovations of the comitium. That building burned down in 52 BC when the supporters of the murdered Publius Clodius Pulcher used it as a pyre to cremate his body.

Santi Sergio e Bacco al Foro Romano (Italian: Saints Sergius and Bacchus at the Roman Forum) also called Santi Sergio e Bacco sub Capitolio (Saints Sergius and Bacchus under the Capitoline) was an ancient titular church in Rome, now lost. Located in the ruins of the Roman Forum, it had been one of the ancient diaconiae of the city and a collect church for one of the station days of Lent, but it was demolished in the sixteenth century.

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.

Sant'Adriano al Foro was a church in Rome, formerly in the Curia Julia in the Forum Romanum and a cardinal-deaconry (a titular church for a Cardinal-deacon).

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.

Santi Luca e Martina is a church in Rome, Italy, situated between the Roman Forum and the Forum of Caesar and close to the Arch of Septimus Severus.

The Curia Julia (Latin: Curia Iulia, Italian: Curia Iulia) is the third named curia, or senate house, in the ancient city of Rome. It was built in 44 BC, when Julius Caesar replaced Faustus Cornelius Sulla's reconstructed Curia Cornelia, which itself had replaced the Curia Hostilia. Caesar did so to redesign both spaces within the Comitium and the Roman Forum. The alterations within the Comitium reduced the prominence of the Senate and cleared the original space. The work, however, was interrupted by Caesar's assassination at the Curia of Pompey of the Theatre of Pompey, where the Senate had been meeting temporarily while the work was completed. The project was eventually finished by Caesar's successor, Augustus Caesar, in 29 BC.The Curia Julia is one of a handful of Roman structures that survive mostly intact. This is due to its conversion into the basilica of Sant'Adriano al Foro in the 7th century and several later restorations. However, the roof, the upper elevations of the side walls and the rear façade are modern and date from the remodeling of the deconsecrated church, in the 1930s.

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.
