In the middle of the picture, here is the Euripus of Agrippa going through the Campus Martius. The Euripus is a straight between Beotia and the Isle of Evia. The narrow channel was presenting an inversion of the stream, which used to fascinate the ancient Greeks. The Romans named as such all the narrow canals dug in their cities. Here was a construction ordered in 27 B.C. by Marcus Agrippa, Augustus’ brother-in-law. It originated in Agrippa’s great Lake, fed itself by the Aqua Virgo. The Euripus discharged its water into the Tiber, between Nero’s bridge and Ælius’ bridge. Its purpose must have been to regulate the level of the water in Agrippa’s Lake.




One of the characteristics of the Euripus is the presence of numerus sepulchres along the canal. The most famous one is Hadrian’s Ustrinum, but another group of sepulchres was gathered close to the stables of the Green Faction ( right at the bottom of the picture ). 1, Cæsar’s sepulchre, 2, Sylla’s sepulchre, 3, Hirtius sepulchre, 4, Pansa’s sepulchre. The sepulchres were constructions built to commemorate the recording of a dead, but did not contain any body nor ashes. A small altar, 6, in the little park next to the sepulchres seemed to be erected for the residents of the area around. On the other side of the Euripus, 7, another much bigger altar, the altar of Mars, 5.







North of the Euripus, a few steps away from Domitian’s Stadium, that can be guessed right of the picture, the workshops of the marble masons.
