Sideni
Σιδεινοί
Eth. Sideni (Σιδεινοί, Σειδινοί, Σιδηνοί), a German tribe on the coast of the Baltic, between the mouth of the river Suebus and that of the Viadus. (Ptol. 2.11.14.) It is possible that Sibini (Σιβινοί) is only a corrupt form of the name of this same tribe. (Zeuss, Die Deutschen, p. 154.)
