Scholars report at least 13 epigraphies (14 inscriptions, as of 2022) attesting either
Arentius or
Arentia, mostly located in central-eastern
Lusitania, and, according to scholar Juan Olivares Pedreño, "well represented" in
Egitania. Both deities are attested either in isolation, or, rarely, as a pair. Olivares Pedreño suggested that their attestation as a pair seems to hark back to similar votive altars of a male and female divine couple in Celtic areas. The pair is also alternatively attested as
Arantius and
Arantia, although this occurrence is rare. In two inscriptions from
Beira Baixa, Arentius is attested as
Arantio Tanginiciaeco and as
Arentio Cronisensi. ==Etymology==
