Selenus chess set
The Selenus chess set is a style of chess set, in use before the standardization of chess pieces that happened after the Staunton chess set was launched in 1849 by games manufacturer John Jaques of London. The Selenus sets were typical of Germany and Northern Europe and are 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.
