The Cloaca Circi Maximi or Cloaca Circi was one of the three main sewers in ancient Rome. Alongside the Cloaca Maxima and Chiavicone dell'Olmo[1]
History
The Cloaca Circi Maximi was built in the Augustan Period to clear Rome of unhealthy bodies of water.[2] It was originally a small stream fed by various sources from around the Porta Capena right through the valley between the Palatine Hill and Aventine Hill, running down to the river Tiber.[3] According to tradition, games and horse races were held in this valley from right after the founding of Rome in the 8th century.[citation needed]
Over the centuries the Circus Maximus was built over the stream, with a channel named Euripus running across it halfway and two bridges carrying the track over it. This sewer would drain the area around the Circus Maximus. [4] It also served as the spina down the middle of the track.[citation needed]
Under Julius Caesar and Augustus the circus and its surroundings were greatly enlarged, covering over the channel, which became a sewer. It was connected to a tunnel modelled on that of the Cloaca Maxima and now terminated on the Tiber upstream of the Cloaca Maxima.[citation needed]
