The diribitorium was a public voting hall situated on the campus Martius in Ancient Rome.
 In this building, the votes cast by the people were counted by election officials.
 Construction of the building was started by Marcus Agrippa but finished by Augustus in 7 BC.
 According to Cassius Dio, the diribitorium was among a number of public buildings that were destroyed by fire in 80 AD, and subsequently rebuilt by emperor Titus.
Agrippa Postumus (26 June 12 BC – 20 August AD 14), also referred to as Postumus Agrippa, was a son of Marcus Vipsanius Agrippa and Julia the Elder.
 He was originally named Marcus Vipsanius Agrippa Postumus in honor of his father, who died shortly before Postumus' birth.
 After the deaths of his older brothers, Lucius (d. AD 2) and Gaius Caesar (d. AD 4), Postumus was adopted by his maternal grandfather, the Roman emperor Augustus.
 In accordance with Roman naming conventions, Postumus' name was changed to Marcus Julius Caesar Agrippa Postumus.
 At the time Augustus considered Postumus as a potential successor, but banished him from Rome in 9AD, for reasons that remain unknown.
 This, in effect, though not in law, cancelled his adoption and virtually assured Tiberius' position as Augustus' sole heir.
 Postumus was ultimately executed by his own guards shortly after Augustus' death in AD 14.
In Greco-Roman mythology, Agrippa (said to have reigned 914-873 BC) ( ) was a descendant of Aeneas and King of Alba Longa, the capital of Latium, southeast of Rome.

 Some speculate that this was done in order to give prestige to Augustus' friend and son in law Marcus Vipsanius Agrippa.
 He was also great great great great grandfather to the famous founders of Rome, Romulus and Remus.
The Baths of Agrippa (Latin: Thermae Agrippae) was a structure of ancient Rome, built by Marcus Vipsanius Agrippa.
 It was the first of the great thermae constructed in the city, and also the first Imperial Bath.

Marcus Vipsanius Agrippa ( ; 64/62 BC – 12 BC) was a Roman consul, statesman, general and architect.
 He was a close friend, son-in-law, and lieutenant to Octavian and was responsible for the construction of some of the most notable buildings in the history of Rome and for important military victories, most notably at the Battle of Actium in 31 BC against the forces of Mark Antony and Cleopatra.
 As a result of these victories Octavian became the first Roman Emperor, adopting the name of Augustus.
 Agrippa assisted Augustus in making Rome a city of marble and renovating aqueducts to give all Romans, from every social class, access to the highest quality public services.
 He was responsible for the creation of many baths, porticoes and gardens, as well as the original Pantheon.
 Agrippa was also father-in-law to the second Emperor Tiberius, maternal grandfather to Caligula, and maternal great-grandfather to the Emperor Nero.
Cydias (Greek: Κυδίας ), a native of Cythnus, who was living in 364 BC, may be presumed to have been a painter of considerable ability, as one of his pictures, representing 'Jason and his followers embarking for Colchis, in search of the Golden Fleece,' was purchased at Rome by the orator Hortensius for 144,000 sesterces.
 Afterwards the work was bought by Marcus Agrippa and placed in the Porticus of Neptune to commemorate his naval victories.
The Pantheon ( or ; Latin: "Pantheon" , from Greek "Πάνθειον Pantheion" meaning "[temple] of every god") is a former Roman temple, now a church, in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD).
 The present building was completed by the emperor Hadrian and probably dedicated about 126 AD.
 He retained Agrippa's original inscription, which has confused its date of construction as the original Pantheon burnt down so it is not certain when the present one was built.
