The Window of Orpheus (, "Orufeusu no Mado"), also known as Orpheus no Mado or Das Fenster von Orpheus, is a Japanese shōjo manga series written and illustrated by Riyoko Ikeda. It is a historical romance and was partially adapted into Takarazuka Revue musical in the title "The Window of Orpheus - Story of Isaak". But the entire story hasn't been adapted into musical. The manga series was published by Shueisha, first in weekly "Margaret" from 1975 to 1976, then in "monthly Seventeen" from 1977 to 1981.
