Kryptádia  

"Many of those earlier researchers who published their findings in Am Ur-Quell, Kryptádia and Anthropophyteia happened to be Jewish, which did not help much in anti-Semitic Europe."--Maledicta, Volume 10, 1988, Reinhold Aman

"Kryptádia: Recueil de documents pour servir à l'étude des traditions populaires (1883-1911). Heilbronn (& Paris). 12 vols., 12mo. Erotic folklore and folksong collections in many languages (except English); yearbook founded by Isidor Kopernicky and Friedrich S. KRAUSS and edited by the French and Italian folklorists, Gaston PARIS (who wrote the Introduction to vol. 1), E. Rolland, Henry Gaidoz, E.-Henri Carnoy, and Giuseppe Pitrè. All the editors and contributors agreed to remain anonymous to protect their professional positions on the companion yearbook, La Tradition. Independently continued 1906-09 as Contributions au Folklore Érotique, Kleinbronn: Gustav Ficker, 4 vols., 12mo, of tales only, all the contributors being pseudonymous. Note also Krauss's much more important continuation yearbook, Anthropophytéia (q.v.), which remained active until stopped by the Nazis in the 1930s."--Jack Horntip[1]
