Irminism (German: Irminenschaft or Irminenreligion) is a current of Ariosophy based on a Germanic deity Irmin supposedly reconstructed from literaric, linguistic and onomastic sources. Among other sources the prefix "Irmin" is documented in the Irminsul "great pillar that supports all"/"Columna Universalis Sustenans Omni", as described in Einhards 'Vita Karoli Magni', and informed by Tacitus (~1st century) via a mentioned Germanic tribe name of Hermiones; the Old Saxon adjective irmin being synonymous to "great, strong". As such it may also have been an epithet of later deities like Ziu (Týr) or Wodan (Odin)).
