 The earliest dateable evidence for the Roman cult is an inscription () from Lambaesis in Numidia (in present-day Algeria), where the commander of Roman troops and de facto governor dedicated an altar in 125 AD.The cult is next attested in Rome, during the reign of Marcus Aurelius ("r." 161-180) when a temple to Jupiter Dolichenus was built on the Caelian Hill.Not much later, the cult is attested in Germany where a centurion of Legio VIII Augusta dedicated an altar in 191 at Obernburg in Germania Superior ().
