The Gadfly was published in 1897 and was written by Ethel Lilian Voynich who was the wife of the owner of the exceedingly strange Voynich MS, which he donated to Harvard's Bieneke library.

Nobody has ever figured out what language this MS is written in, or indeed if it is written in a language. (Cf. the Codex Seraphinus.)
