Erudinus

No mythic origin story for Erudinus is preserved in the cited sources. The only attested provenance of the deity is epigraphic: an inscribed altar discovered in 1925 by Hermilio Alcalde del Río at Monte Dobra, near Torrelavega (Cantabria). The inscription demonstrates that an individual (Cornelius Vicanus, son of Cestius) set up an altar to "DEO ERVDINO" using Roman dating conventions; beyond this dedicatory act and the archaeological findspot and museum history (the original in the Museum of Prehistory and Archaeology of Cantabria and a replica installed in Sierrapando/Torrelavega), no narrative of origin or cultic founding is provided in the sources.

No iconography, anthropomorphic description, or visual representation of Erudinus is recorded in the available sources. The deity is known only from the inscribed altar itself (text transcribed as "CORNE(lius) VICANVS / AVNIGAINV(m) / CESTI(i) F(ilius). ARA(m) / POSSVIT. DEO / ERVDINO. X. K(alendas)/ AVGV(stas). MA(llio). EV(tropio) CO(n)s(ulibus)."). The original stone altar is part of the collection of the Museum of Prehistory and Archaeology of Cantabria, and a replica has been installed publicly in the Sierrapando area of Torrelavega (previously on Serafin Escalante street from 2001–2012); no sculptural depiction or emblem associated with the name is attested.

The sources record no powers, domains, or behaviors for Erudinus. Beyond the fact that a private individual dedicated an altar to him, there is no evidence of miracles, mythic deeds, patronages, or interactions with worshippers in the cited material. Interpretations about the deity's functions would be speculative and are not present in the sources.
