The Irminones, also referred to as Herminones or Hermiones (Ancient Greek: Ἑρμίονες), were a large group of early Germanic tribes settling in the Elbe watershed and by the first century AD expanding into Bavaria, Swabia, and Bohemia.
[2] Tacitus also mentioned the Suebi as a large grouping who included the Semnones, the Quadi, and the Marcomanni, but he did not say precisely to which (if any) of the three nations they belonged.
In the so-called Frankish Table of Nations (c. 520), probably a Byzantine creation, the son of Mannus, who was the ancestor of the Irminones, is named Erminus (or Armen, Ermenius, Ermenus, Armenon, Ermeno, as it appears in various manuscripts).
Jǫrmunr, the Viking Age Norse form of the name Irmin, can be found in a number of places in the Poetic Edda as a by-name for Odin.
Some aspects of the Irminones culture and beliefs may be inferred from their relationships with the Roman Empire, from Widukind's confusion over whether Irmin was comparable to Mars or Hermes, and from Snorri Sturluson's allusions, at the beginning of the Prose Edda, to Odin's cult having appeared first in Germany before spreading up into the Ingvaeonic North.
