In the topography of ancient Rome, the Tarentum or Terentum was a religious precinct north of the Trigarium, a field for equestrian exercise, in the Campus Martius.
[3] The location of the Tarentum is indicated primarily by the discovery in 1930 of the inscribed record of the Saecular Games (acta) held in 17 BC, which traditionally took place there.
[5] The Tarentine Games were presented most notably in 249 BC, as a "crisis ritual"[6] during the First Punic War, in accordance with the Sibylline Books.
The ludi took the form of three-night rites[7] and horse races to honor Dis and Proserpina, the divine couple who had an underground altar at the site.
[8] In a common version of the myth, Proserpina (Greek Persephone) was abducted by the ruler of the underworld and driven underground in his chariot to become his bride and queen.
