Hypothesis of Dr Alexander Amelkin: In the Blutenburg Castle (Schloss Blutenburg, old ducal country seat in the west of Munich, Germany) balneotherapist Caspar Bernauer (1385-1450) after the execution of his daughter Agnes wrote the story of the castle and its inhabitants in his native Post-Rhaetian language. So the Voynich Manuscript was born. The castle was built in 143840 between two arms of the River Würm for Duke Albert III Wittelsbach, Duke of Bavaria in the tradition of the Danube School of Architecture using "dovetail" elements for the fortress walls. In 1440, Albert refused the offered Bohemian crown and presented one of the Voynich Manuscript copies to the House of Habsburg in Prague. Therefore, the key to the mysterious Voynich Manuscript code should be sought in the archives of the House of Habsburg in Prague and of the House of Wittelsbach in Munich. According to my theory the Rhaetian people (to which belonged Caspar Bernauer) are descended from the Proto-Basques. Since I defined the language of the manuscript as Post-Rhaetian, it could be probably in some degree similar to Basque language. According to John D. Bengston, Helmut Rix, Ed Robertson and Sergei Starostin Rhaetian language could be relative to Basque, Etruscan and Hurrian languages.
