The names Varini (Tacitus), Varinnae (Pliny the Elder), Ούίρουνοι or Viruni (Ptolemy), Varni or Οὐάρνων (Procopius), Wærne/Werne (Widsith) and Warnii (Lex Thuringorum) probably refer to a little-known Germanic tribe. The name would have meant the "defenders". They originally lived in northern Germany, but may have moved to the west during the Migration Era. They are often called Warni and Warini in English. The earliest mention of this tribe appears in Tacitus' Germania, where he wrote:
(Original Latin) "Reudigni deinde et Aviones et Anglii et Varini et Eudoses et Suardones et Nuithones. Nec quicquam notabile in singulis, nisi quod in commune Nerthum, id est Terram matrem, colunt eamque intervenire rebus hominum, invehi populis arbitrantur. ..." --Tacitus, Germania, .
(English translation) "There follow in order the Reudignians, and Aviones, and Angles, and Varinians, and Eudoses, and Suardones and Nuithones; all defended by rivers or forests. Nor in one of these nations does aught remarkable occur, only that they universally join in the worship of Herthum (Nerthus); that is to say, the Mother Earth."--Tacitus, Germania, , translated 1877 by Church and Brodribb.
