Das Schach- oder König-Spiel

Duke Augustus was one of the most well-read and educated European rulers of his time. The famous Bibliotheca Augusta in Wolffenbüttel is named after him. In his youth he wrote the first German language book on chess, Das Schach- oder König-Spiel. it was published under the pseudonym Gustavus Selenus, the first part of which is a rearrangement of the letters in Augustus, while the second derives from Selene = Luna and forms an allusion to Lüneburg. The book is a great rarity today, not least in the apparently complete condition in which it is found here.
