Sporoi (Greek: Σπόροι) or Spori was according to Eastern Roman scholar Procopius (500–560) the old name of the Antes and Sclaveni, two Early Slavic branches. Procopius stated that the Sclaveni and Antes spoke the same language, but he did not trace their common origin back to the Veneti (as per Jordanes) but to a people he called "Sporoi". He derived the name from Greek σπείρω ("I scatter grain"), because "they populated the land with scattered settlements".
Roman bureaucrat Jordanes wrote about the Slavs in his work Getica (551): "although they derive from one nation, now they are known under three names, the Veneti, Antes and Sclaveni" (ab unastirpe exorti, tria nomina ediderunt, id est Veneti, Antes, Sclaveni); that is, the West Slavs, East Slavs, and South Slavs. He stated that the Veneti were the ancestors of the Sclaveni and the Antes, the two having used to be called Veneti but are now "chiefly" (though, by implication, not exclusively) called Sclaveni and Antes. Jordanes' Veneti and Procopius' Sporoi were used for the ethnogenetic legend of the Slavs, the ancestors of the Slavs (the subsequent ethnic group name).
