Roigos (Ῥοιγος; the Latin form would be Rhoegus) was an Odrysian king in Thrace during the 3rd century BC.
He is known primarily from his rare coinage[1] and a graffito inscription from the Kazanlăk Tomb revealed in 2008 by Konstantin Bošnakov.
[2] Roigos' obscurity contrasts with the apparently secure attribution of the opulent Kazanlăk Tomb to him, and his precise chronological position and relationships remain unclear.
Given the tomb's location near Seuthopolis and the widespread tendency to associate most spectacular finds in the area with the town's famous founder Seuthes III, Roigos has been declared a son of Seuthes III by some authors,[3] and Gonimase (Gonimasē), wife of a Seuthes, has been proposed as Roigos' mother.
This would be compatible with a mid-3rd century date for the destruction of Seuthopolis,[6] which has been proposed as a correction to the more traditional association of the town's end with the Celtic incursions of the 270s BC[7] (although the destruction of the royal residence need not have a direct bearing on the date of the tomb).
