Their many notable collaborators have included Aleksander Madzar, Alasdair Beatson, Simon Rowland-Jones, Daniel Lebhardt and Olivier Stankiewicz.

 

Our name is derived from the Castalian Spring in the ancient city of Delphi. According to Greek mythology, the nymph Castalia transformed herself into a fountain to evade Apollo’s pursuit, thus creating a source of poetic inspiration for all who drink from her waters. Herman Hesse chose Castalia as the name of his futuristic European utopia in The Glass Bead Game. The novel’s protagonist, a Castalian by the name of Knecht, is mentored in this land of intellectual thought and education by the venerable Music Master.
