Attestation – Evidence of Intarabus is sparse with most inscriptions being found within traditional Treverian lands, modern Trier being the main hub. Sometimes interpreted as Roman Mars, without a traditional gaulish consort, or as Intarabus uninterpreted with a reference to the imperial cult. An inscription from Trier reads:
In h(onorem) d(omus) d(ivinae) deo Marti Inta/rabo Vitalius Victorinus / et Novellinius Maiius fa/num et simulacrum a fundam/[ent]is ex voto r[e]stituerunt (1).
Translated: To the God Mars Intarabus, in honor of the Divine House, because of the vow made by Vitalius Victorinus and Novellinius Maiius, the sanctuary and likeness of Intarabus from the foundations is restored.
The reference to the Imperial House is interesting but not unusual for the area. Another from Ernzen follows:
(Marti In)tarabo (aediculam) sua impensa …. L. Germanius (restituit) … .us d(ono) d(edit) (2).
Roughly translated as: To Mars Intarabus, L. Germanius has renewed a shrine at his own expense …-us gave as an offering.
There is as well an inscription found at a Mithraeum in the Mackwellir site of the Bas-Rhin region in france. Invoking both Mithras and Narius Intarabus showing a shift in the practices and local cults to the god. Narius comes from Gaulish denoting a ‘Hero’, ‘Lord’, or ‘powerful, noble, greathearted man’.(3)*
Etymology – According to Delamarre, the name might mean “in between rivers” possibly coming gaulish enter, entar (in between) and abu– (river). (4)
TFA Interpretation – Within TFA, Intarabus is the great hero that leads his warriors under the patronage of Magusanus. He is the Divine Antentor apotheosized into Intarabus within the line of the heroic Heracles and by extension, an avatar or Triverian version of the Gallic Hercules. Antenor, being the counselor to the Trojan Priam, uses his eloquence to inspire more warriors to the cause of his patron and shares the divinity given to him by Magusanus to those he has called. Interpreted with Mars, Intarabus is the keeper of boundaries, guarding against Helwargen and those that would bring destruction. Intarabus, by his namesake, is the one between the rivers suggesting liminality that would fall in line with his “hero made god” nature.
Note on Antenor – According to the Liber Historiae Francorum, after the fall of Troy while Aeneas fled to Italy, Priam and Antenor fled north and founded Sicambria along the banks of the Tanais in Pannonia. After aiding the Romans in their conquest over the Alans in the Maeotian swamps, the Trojans, now deemed Franks, failed an attempt to turn against the Romans and were pushed west towards the Rhineland. This mythic account ties the Franks to the Trojan refugees to the line of Priam thus bringing Antenor to the service of Magusanus.
