The Selenus chess set is one of the most elegant classical chess set styles in use before the standardization of chess pieces that happened after the Staunton chess set was launched, in 1849 by John Jaques of London games manufacturer. The Selenus sets, were typical of Germany and Northern Europe and named after Gustavus Selenus, the pen name of Augustus the Younger, Duke of Brunswick-Lüneburg, author of the Chess or the King's Game (German: Das Schach- oder Königsspiel), an important chess manual published in the 17th century. The standard included delicate lathe turned bases and shafts and tiers with circlets resembling crowns. Pieces were distinguished by heights, the number of tiers and sometimes by symbols.
These chessmen can also be called "Garden Chess Sets" because their theme frequently consisted of "formal flower gardens" - Kings and Queens were Fountains; Bishops and Pawns were flowers; Knights were gentle horses; and Rooks became civic towers instead of battlements.
In England they were frequently called "Tulip Chess Sets".
