The Window of Orpheus (オルフェウスの窓, Orufeusu no Mado), also known as Orpheus no Mado or Das Fenster von Orpheus,^[1] is a Japanese shōjo manga and historical romance series written and illustrated by Riyoko Ikeda. The Manga was partially adapted into Takarazuka Revue musical entitled The Window of Orpheus - Story of Isaak, however this does not include the story in its entirety.^[2] The manga series was published by Shueisha, first in weekly Margaret from 1975 to 1976,^[3] then in monthly Seventeen from 1977 to 1981.^[4]

The series was collected in 18 bound volumes. It takes place in Germany, Austria and Russia with the backdrop stories of the World War I and the Russian Revolution.

Riyoko Ikeda published her first long story The Rose of Versailles in 1973. The story had two main themes. One is the life of Marie Antoinette, the Queen of France. And the other is the love and the life of Oscar François de Jarjayes. These two themes were in resonance, and The Rose of Versailles got great popularity and success.

On the other hand, The Window of Orpheus has the three themes.^[5] The one is the life and the love of another Oscar François, that is, Julius von Ahrensmeyer. The second is the story of music and the life of a musician (Isaak) which Ikeda truly wished to describe.^[6] And the third is the historical romance in the Russian Revolution. Ikeda wrote the French Revolution in the Rose of Versailles, but she did not satisfy it.^[7] She wanted to describe the deeper human drama in the background of another revolution.

Riyoko Ikeda had learned piano from her very young days. She had loved music and wished to become a professional musician. But she got aware that she hadn't talent. She gave up, but the passion for music has vividly existed through her life.^[8][9]

In October, 1973, after completed the long story The Rose of Versailles on the Margaret, she travelled to the Europe with her friend manga artists Toshie Kihara and Yōko Tadatsu (JA) for about one month or one and half months. They reached and stayed at an old city of Regensburg by chance.^[10] There, Ikeda was inspired and visioned the stories of the music and romance which she could not fully express in The Rose of Versailles.

There were two obstacles in writing the first long story La Rose de Verailles. One was the editors of Margaret who asked and forced her to make Oscar a strong, high pride female protagonist. The true protagonist, the true "Rose" was Marie Antoinette though. And the other was the fact that the readers of Margaret were early teens girls. What Ikeda wished to depict was the adult human love and life, but the media Margaret did not allow it.^[3]

Julius is apparently a feminine and sensitive aspect of Oscar François.^[11][12] Ikeda did not want to weaken the themes of her manga arts. She calmly judged that Margaret was not proper media where she expressed and realized her true themes. She changed the media from Margaret to Seventeen. Ikeda firmly decided she would never compromise in her creation of the work.^[3] Her decision gave birth the story The Window of Orpheus.

The story consists of four Parts. It encompassed over 30 years, from 1893 to 1924. Through this four parts story, there are three major characters: Julius von Ahrensmeyer, a daughter of the aristocratic house Ahrensmeyer of the Kingdom of Bayern, Alexei Mikhailov (alias Klaus Sommerschmitt), a son of the Marquis House of the Russian Empire, and Isaak Gotthelf Weisheit, a prodigious pianist born in the common people.^[13][14][15]

In the Autumn of 1903,^[16][17] a boy comes to the Saint Sebastian music school as a transfer student in Regensburg, Bayern, Germany. His name is Isaak. Hearing of a certain legend, he goes up the tower and stands in front of the old window with curiosity. He looks down through the window, and sees a person walking by. It looks like a girl at a glance, but that person is another transfer student, called Julius.

The next day, Julius hears of the legend from Isaak. Saint Sebastian is an all boys school, but Julius is a cross-dressed girl, not a boy. Thinking over the legend, Julius looks up the window. There is a person, and he sees Julius through the window. It is Klaus, an upper grade student. Here, three people, Isaak, Julius and Klaus (Alexei) are combined through the legend. The window is called the Window of Orpheus.

There is a legend dating back about 400 years ago in the Catholic Saint Sebastian school. It says if a man stands in front of the Window of Orpheus, and if he first sees a figure of a female through this window, he will fall in love with that female. But it will bring pain, for the love will end up like the tragic Greek myth of Orpheus and Eurydice.

Julius, Isaak, and Klaus are tied to the legend of the window. And there are other people who are tied to this legend as well. In the shadow of the legend of the window, the four parts long story opens.

The stage of Part 1 is Regensburg in the Kingdom of Bayern, Germany, 1903 to 1905.

Julius is a girl. Her mother Renate was a concubine of Julius' aristocratic father Ahrensmeyer. Renate was abandoned by him when she had Julius. For revenge against the Ahrensmeyers, Renate gave her daughter a male name Julius and raised her as a boy.

After the death of Ahrensmeiyer's wife, Julius and her mother are accepted into the Ahrensmeyer house, and since there are no other male children, Julius becomes heir of the Ahrensmeyers. Julius learns piano from her earliest days, so she enters the Saint Sebastian school as a boy when she is 15.

Julius spends her school life with friends Isaak, Klaus and other students. But the legend of the Window casts a shadow on her mind since she is a girl, and she starts feeling a kind of love toward Klaus, a manlike, yet mysterious student.

There are conflicts between the rich and the poor, the noble and the common. The Ahrensmeyer is the old aristocratic house. The newly rising merchant house Kippenberg is a rich family, while the Ahrensmeyer's is declining. Moreover, strange and terrible events take place to the Ahrensmeyers in succession. There seems to be some secret with the Ahrensmeyers, something that may have ties to the German Empire and Russian Empire.

More of the secrets of the Ahrensmeyers are unraveled, but in the course of the search, Klaus, real name Alexei Mikhailov, suddenly disappears, having returned to his homeland, Russia. Julius, now having fallen in love with Klaus, follows him to Russia. Isaak remains alone in Regensburg, but is later invited to the Vienna Music Academy, and becomes a student there. Thus Part 2 begins.

The stage of Part 2 is Vienna, the capital of Austria, 1907 to 1920. The protagonist is Isaak Weisheit.^[19]

In Vienna, Isaak meets various people. In the blessed environment, Isaak's talent begins to bloom. He befriends a mysterious student named Reinhard, and one day hears the strange music Reinhard plays. The piece turns out to have been composed by Reinhard, who is a musical prodigy.^[20] However, it seems to be impossible to play this music on piano, with Reinhard even damaging his fingers in the attempt, but Isaak is determined to try.

Isaak debuts as an outstanding new pianist, and Reinhard gives him advice and a warning: "You should know what is true art". Learning from Reinhard and Wilhelm Backhaus, Isaak opens up a new frontier of musical art. He later performs with a Russian violinist named Anastasia, who turns out to be a member of a Russian revolutionary group. She gives Isaak a message from Alexei (Klaus) before they go their separate ways.

Isaak later marries Roberta, an acquaintance of his from Regensburg, and is later called off to war.

He returns from World War I, but his fingers have been damaged, and he cannot play piano anymore. He later returns to Regensburg with his son Jubel, and when walking along an old, familiar street, Isaak meets a beautiful woman.

Part 3 is mainly set in Sankt Peterburg and Moskva in Russia, 1893 to 1917.

The story begins about 10 years before the three main characters, Isaak, Julius and Klaus (Alexei) meet in Regensburg, Germany in 1903. In the Spring of 1893, Alexei is accepted into the Marquis house Mikailov after his mother's death. He meets his elder brother Dmitri, who is secretly a revolutionary, but also famous as a genius violinist. Alexei learns the spirit of brave men and a passion for music from Dmitri. But Marquis Dmitri Mikhailov is shot to death in an act of betrayal.

Alexei and Alraune, the fiancée of Dmitri, flee from Russia, but after the several years of joyous school life, his homeland and comrades call Alexei back to Russia in 1905. At the Sankt Peterburg station, he sees Julius has followed him, but he runs from her. Julius is searching for Alexei when she gets caught up in the riots and is shot. When she wakes up, she is in the gorgeous mansion of Marquis Yusupov, where she is declared his prisoner.

Alexei and his revolutionary comrades are working for the new Russia. They establish the Soviet (the Committee), but the revolutionaries are divided into Mensheviks and Bolsheviks. Yusupov realises that Rasputin is the enemy of Russia and the Royal House, and does not trust him at all. Yusupov encounters Alexei, but he does not kill or arrest him since Alexei saved his younger brother's life. Alexei is captured by other authorities, however, and sent to a jail in Siberia, where he is to be sentenced to death. Marquis Yusupov sends a petition to the authorities, sparing Alexei's life.

Anastasia is arrested in Vienna and sent to Russia where she is sentenced to a Siberian prison. Bolshevik revolutionaries try to rescue her, but their plan is foiled by Antonina's information. In the confusion, Julius is reunited with Alexei, but she briefly does not remember him due to a bout of amnesia.

The Russian Empire is now a melting pot of conspiracies and power struggles. Marquis Yusupov decides to assassinate Rasputin of behalf of the Tsar Nikolai II. Meanwhile, Julius and Alexei have rekindled their romance, and Julius has conceived Alexei's child. Now, Alexei and Yusupov face the fates that will bring them to ultimate destinies.

In the cold water of the Neva River, Alexei remembers the Window of Orpheus. He is suddenly riddled with bullets, collapsing with his final thoughts being of Julius. Marquis Yusupov finds him, and respectfully closes his eyes. He raises a pistol and says to himself: "I've made two mistakes in my life, but I never regret". His sister Vera Yusupova departs Russia for Regensburg with Julius, in order to keep the promise she made to her brother.

Kerenski seizes power, but he soon escapes from the Winter Palace, and the Bolsheviks win. Thus Vladimir Lenin declares their victory of the Revolution in November 1917.^[21]

The main stage of Part 4 is again Regensburg, Weimar Republic.

In 1920, Julius walks to the Orpheus Window tower in Regensburg. There she sees an unknown man, later revealed to be Isaak. As he makes eye contact with Julius, Part 4 officially begins.

Maria Barbara has been trying to nurse Julius back to health, but Julius still cannot remember anything. Isaak, who now works in the downtown tavern, and David try to help Maria in her attempts. Julius wants to recover her memories, but various trials all fail. One morning they read a newspaper article which says a certain unidentified woman^[22] insists she is a royal princess of Russia, the youngest daughter, Anastasia. Ultimately, Julius goes to Berlin to meet a woman in an attempt to recover her memories.

In Berlin, while Julius never meets the woman, she understands that the secret of her house is somehow related to the large fortune which the Russian Tsar deposited in the German Imperial bank in secret. Julius now knows the truth, and that is good enough for her.

The Window of Orpheus has a bit complicated structure. The story consists of the four Parts. But from the contents of each part, it can be said that there are three independent stories. These stories are apparently assigned to each Part.

• Story 1: The Story of the Secret of the House Ahrensmeyer (Part 1, Part 4)
• Story 2: The Story of Isaak and the Music (Part1, Part 2, Part 4)
• Story 3: The Story of the Russian Revolution (Part 3)

Part 1 contains the prologue of the Story 2, and it contains the interlogue of the Story 3. And Part 4 contains both the epilogue of the Story 1 and the Story 2. And the Story 2 isn't finished here in the original plan.^[26]

At the first vision of the author, it was the story of a pianist and the music.^[11] That is, the Story 2 - Isaak and the Music was "the Window of Orpheus". The Story of Isaak and the Story of Russian Revolution have no relation. Alexei was created to introduce the Russian Revolution. And Julius was formed to connect these situations.^[27][28]

In the plan of the author, the story was scheduled to continue after the death of Alexei and Julius. The son of Isaak, Jubel, would be a great pianist, and Isaak himself would be a grand master Composer in Vienna.^[26] But Ikeda could not write these stories, and therefore The Window of Orpheus is her "Life Work".

The Window of Orpheus is one of the representative Japanese shōjo manga in 1970s. Another Ikeda's work The Rose of Versailles has had higher reputation and popularity. But according to one editor, Orpheus has a higher completeness than Versailles in the view point of the artistic achievement as manga story, including its picture quality.^[29]

The 1970s is the epoch for Japanese shōjo manga from the various view points in cultural and social phenomena. The fruits of the Year 24 Group were ripened in this period, and the Japanese manga and subcultural industries themselves had largely developed and diversified in this epoch.^[30]

Frederick Schodt introduced the Japanese manga culture in the 1970s in his book. In the section "Flowers and Dreams", there are about 20 these images selected and shown. One of them is the scene from the Window of Orpheus. The image presented is the last scene of Marquis Yusupov.^[31]

The manga series was published in 18 bound volumes in Margaret comics series of Shueisha.^[32]

"Mg" indicates stories are published in weekly Margaret. "Sv" indicate stories are published in monthly Seventeen.

There are various versions of Japanese manga books of The Window of Orpheus. In Japanese, five real paper book series and one E-book series are known.^[35] The manga series is also published in the languages other than Japanese.^[36]
