The Great Altar of Unconquered Hercules (Latin: Herculis Invicti Ara Maxima) stood in the Forum Boarium of ancient Rome. It was the earliest cult-centre of Hercules in Rome, predating the circular Temple of Hercules Victor. Roman tradition made the spot the site where Hercules slew Cacus and ascribed to Evander of Pallene its erection.  Virgil's 'Aeneid' tells of Evander relaying the original creation of the Ara Maxima to Potitius and the Pinarii. 
The original altar burned in the Great Fire of Rome, CE64, but was rebuilt and was still standing in the fourth century. A tentative identification of a tufa platform in the crypt of Santa Maria in Cosmedin with the foundation of the altar has been made by Filippo Coarelli and other archaeologists.
Various references, with Varro as their source, justified the exclusion of women from ceremonies here, or of partaking in the sacrificial meats. The rites at the Ara Maxima were unique within the cult of Hercules in that they were performed ritu Graeco, with heads uncovered.
(Sextus or Marcus) Anicius Faustus Paulinus or Paulinianus (c. 240 - aft. 300) was a Roman senator who was appointed consul in AD 298.Evander of Pallene
In Roman mythology, Evander (from Greek Εὔανδρος Euandros, "good man" or "strong man": an etymology used by poets to emphasize the hero's virtue) was a culture hero from Arcadia, Greece, who brought the Greek pantheon, laws, and alphabet to Italy, where he founded the city of Pallantium on the future site of Rome, sixty years before the Trojan War. He instituted the festival of the Lupercalia. Evander was deified after his death and an altar was constructed to him on the Aventine Hill.
In addition, Strabo, mention that one of the stories about Rome is that it was an Arcadian colony and was founded by Evander.Forum Boarium
The Forum Boarium (Italian: Foro Boario) was the cattle forum venalium of Ancient Rome. It was located on a level piece of land near the Tiber between the Capitoline, the Palatine and Aventine hills. As the site of the original docks of Rome (Portus Tiberinus), the Forum Boarium experienced intense commercial activity.
The Forum Boarium was the site of the first gladiatorial contest at Rome which took place in 264 BC as part of aristocratic funerary ritual—a munus or funeral gift for the dead. Marcus and Decimus Junius Brutus Scaeva put on a gladiatorial combat in honor of their deceased father with three pairs of gladiators.
The site was also a religious centre housing the Temple of Hercules Victor, the Temple of Portunus (Temple of Fortuna Virilis), and the massive 6th or 5th century BC Great Altar of Hercules.Hercules (disambiguation)
