Aequum Tuticum was a Roman vicus in southern Italy, about 35 km east-northeast of Beneventum. The site lies beside Saint Eleuterio hamlet, overlooking at an elevation of 575 m, about 15 km north of the modern Ariano Irpino, within Irpiniahistorical district. The vicus name is partly Latin and partly Oscan. Aequum Tuticum was founded near the intersection of two ancient Roman roads: and, whose existence is attested by two II century b.C. milestones showing the inscription "Marcus Aemilius Lepidus". The vicus was first mentioned by Marcus Tullius Cicero in a 50 b.C. letter addressed to his friend Titus Pomponius Atticus; he described the place as a regular stopping point along the route to Apulia. and Via Herculea, two branches of ancient Via Appia At the time of Adrianus, when the vicus was a possession of the gens Seppia from Beneventum, it became a relevant road junction because the vicus lay at the crossroads between Via Traiana and. Near Aequum Tuticum, just to the north, a stretch of Via Traiana has been discovered along torrent, whereas two sepulchral areas show up to the south and west; aerial photographs have also shown the route of Via Herculea. Archaeological excavations, carried out between 1990 and 2000, found wall structures and evidence from the Roman era such as ceramics, inscriptions, funerary steles and coins. The oldest complex appears to be a thermal structure dating back to 1st century. The central compartment, named frigidarium, shows up a mosaic in black and white tiles. There are also a series of 2nd century rooms arranged in rows in. The settlement suffered the damage from an earthquake in the second half of 4th century, but shortly afterwards a villa, showing a compartment decorated with a vast polychromatic mosaic, was installed above the older buildings. Aequum Tuticum, mentioned in Tabula Peutingeriana and Itinerarium Antoninum, was then abandoned by 6th century, presumably due to Barbarian invasions. The high-medieval sources mention the locality first as Casalis Janensis, and then as Saint Eleuterio, the latter being a name of Greek-Byzantine origin. However, there are traces of a resettling in the Middle Ages, when the ancient Roman walls were incorporated into those of a building forming part of the new inhabited hamlet also called "Saint Eleuterio", then in turn abandoned. A collection of finds from Aequum Tuticum is kept in while several dozen inscriptions and architectural elements are collected in a lapidary inside the.
