Carl Friedrich August Grosse also known as Edouard Romeo Vargas-Bedemar was a German author, translator, aesthetic philosopher, and mineralogist. He is best known for his gothic novel Der Genius, which was translated into English by Peter Will as Horrid Mysteries, subtitled "A Story From the German Of The Marquis Of Grosse" and subsequently referenced by Jane Austen as one of the seven 'horrid novels' in Northanger Abbey. His philosophy focused on the aesthetics of sublimity, following the work of Friedrich Schiller, and provided one of the first philosophical treatments of imagination.
