Deceneus

 ( Dacians ) 

Deceneus or Decaeneus (Greek: Δεκαίνεος, Dekaineos) was a priest of Dacia during the reign of Burebista (82/61–45/44 BC). He is mentioned in the near-contemporary Greek Geographica of Strabo Book VII, ch. III, §5 (trans. H. C. Hamilton and W. Falconer). and in the 6th-century Latin Getica of Jordanes, where he is called Dicineus.

In Strabo's account, Decaeneus is the second most powerful man among the Dacians and Getae tribes and their high priest. His support for Burebista is key to the latter's attaining and holding power over all the tribes. He succeeded to political power in a reduced area after Burebista's death, but he does not appear to have taken the royal title.Ioana A. Oltean, Dacia: Landscape, Colonization and Romanization (Routledge, 2007), pp. 47, 49. Jordanes' account is derivative of Strabo's. He credits Dicineus with bringing civilization to the Goths (whom he equates with the Getae).Shami Ghosh, Writing the Barbarian Past: Studies in Early Medieval Historical Narrative (Brill, 2015), pp. 49–50. He places him between Zeuta and Zalmoxis as second in a succession of Dacian wise men.
