The Forum of Caesar (Foro di Cesare) was built by Julius Caesar near the Forum Romanum in Rome in 46 BC. Caesar decided to construct a forum bearing his name in the northeast section of the Forum Romanum, of which he purchased a very expensive, select amount of parcels of land in that area. The Forum spanned from the Argiletum on the southeast side of the Forum Romanum to the Atrium Libertatis and spanned 160 meters by 75 meters. As part of the dedication, lavish games were offered and funded by Caesar, indicating the staggering cost and thus the personal interest that Caesar had invested in the project.
The Forum of Caesar originally meant an expansion of the Forum Romanum. The Forum, however, evolved so that it served two additional purposes. As Caesar became more and more involved in this project, the Forum became a place for public business that was related to the Senate in addition to a shrine for Caesar himself as well as Venus Genetrix.
Before his assassination, Caesar would have the Senate meet him before his temple, an act deemed very unpopular by the Senate. The Forum of Caesar also had an effect on the Curia, which Caesar began to reconstruct in 44 BC. This reconstruction moved the Forum of Caesar much closer to the Curia. The ten tabernae located on the western side of the Forum and its now close approximation to the Senate house symbolized the unity that Caesar felt between himself and the Senate.
Caesar also placed a statue of his favourite horse in front of the temple. Following his assassination, a statue of Caesar riding this horse was added. The Temple of Venus Genetrix was completed after Caesar's assassination by Roman senators, which included lavish games in reference to Caesar's original dedication to the Forum. Caesar had plans for this temple well in advance, having dedicated the construction of a temple to Venus Victrix at the climactic Battle of Pharsalus in 48 BC, though never being able to see its completion. This original dedication was done because it was Pompey's favourite goddess, and Caesar hoped to gain the goddess's favour before the battle against Pompey.
The temple was re-built after the removal of the gap between the Capitoline Hill and the Quirinal Hill, under the reigns of Domitian and Trajan; during the adaptation of the gap, a second floor of tabernae was created behind the west portico of the square and a building with pillars made of tuff blocks, named Basilica Argentaria, was erected. The new temple was inaugurated in the same day as the Trajan's Column, on May 12, 113.
Following the reigns of Caesar and Augustus, a total reconstruction of the Forum took place, headed by the Roman Emperor Domitian. Why this reconstruction occurred is not exactly known. Under the reign of Titus, a massive fire ravaged the city in AD 80, including the Forum Romanum. The Forum of Caesar was not rebuilt until AD 95, however, indicating that perhaps Domitian had a personal interest in the reconstruction. This could be seen in the separation of the Curia from the Forum, symbolizing a reversal of Caesar's wish to have the Senate closely connected with him. Not much senatorial business took place in the Forum afterwards, except for the secretarium senatus in the 4th century.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
