Prologue : 序篇 降矢木一族釈義
"聖アレキセイ寺院の殺人事件"
references the short story 聖アレキセイ寺院の惨劇
"ボスフォラス以東に唯一つしかないと云われる降矢木家の建物が、明らかに重大な理由の一つとなっているのだった。"
Also refers to 聖アレクセイ寺院ケルト・ルネサンス式
Castle Building Style from the 15th century with french architecture influence
"マッケイの古めかしい地理本"
Note:: Several geography books (prior to 黒死館殺人事件) were written by people named Mackay. I’m not sure we can know exactly which one this refers too, possibly this one (considering date and country ) : Book of MacKay, which would be consistent with Celtic Renaissance, but there is no illustration of castles in it…
"竜宮の乙姫"
references the children’s tale 浦島太朗
"プロヴァンヌ城壁"
Fortified walls of the city of Provins in France
link in french
link in english - Provins Tourist Assocation website
"ケンネル殺人事"
references SS. Van Dine 's The Kennel Murder Case. 小栗虫太郎’s writing has often been compared to Van Dine’s Philo Vance series. More info on Philo Vance
"ボルジアの壺"
Might reference a haunted artifact that I’ve found referenced in this book in japanese, and in english. However, this was published in 1947, so obviously not directly what is referenced here. Maybe in M.R James which is said to have influenced Dare, but I can’t find a direct reference.
After feeding it all the links, ChatGPT thinks there is no real link, just a general reference to the Borgias poisoning people.
"「一四一四年聖ガル寺発掘記」"
Reference the Abbey of St Gallen in Switzerland,
which is a Unesco World Heritage site. However, there is no 1414 excavation; the most important event et that time was the Council of Constance (1414-1418) which did have a major impact on the Abbey
"寺門義道"
doesn't seem to be an actual heraldry specialist.... or any actual person for that matter"千々石清左衛門直員"
Is an actual japanese envoy to Europe from the Tensho period :
english link
japanese link
"大友宗麟"
Is a real Daimyou, who sent the Tensho embassy to Rome, as well as expeditions to Goa
"クラウジオ・アクワビバ"
Italian priest and General of the Jesuit order in the 16th century; he is established several missions overseas, including in Japan. He is regarded in importance as the second founder of the Jesuit order
"ジェンナロ・コルバルタ"
made up character"フランチェスコ大公妃カペルロ・ビアンカ殿"
Not the same Francisco as before (i.e : not 大友宗麟) . This is Francesco I dei Medici
and his wife, Bianca Capello
"つまり、降矢木の血系が、カテリナ・ディ・メディチの隠し子と云われるカペルロ・ビアンカから始まっていると云う事なんだが、その母子が揃って、怖ろしい惨虐性犯罪者と来ている。カテリナは有名な近親殺害者で、おまけに聖バーセルミュウ斎日の虐殺を指導した発頭人なんだし、また娘の方は、毒のルクレチア・ボルジアから百年後に出現し、これは長剣の暗殺者と謳われたものだ。" SPOILERS
This is false : Bianca Capello, though linked through marriage to Catherine of Medicis, is not her daughter, hidden or otherwise. There is no family link to the Borgias. And while all three women are known for ruthlessness and poisoning, there is no mention of sword killings anywhere"カテリナ・ディ・メディチ"
"シャルコー"
Jean-Martin Charcot : French doctor who basically invented the field of neurology. While he did write/speculate about family origins in neurology and psychiatric diseases, he did not write about criminology…
"また、フィリップ三世が巴里中の癩患者を焚殺したと云う事蹟を聞いて、六代後の落魄したベルトランが、今度は花柳病者に同じ事をやろうとしたそうだ" SPOILERS
This is false : the true king Philippe III of France never established any kind of punishment against lepers; that was Philippe V, and in the Languedoc region, not in Paris. This Philippe V was also king of Navarre, and known there as Philippe II; there is another, still different King Philippe III of Navarre, which also has nothing to do with pogroms against lepers"ブラウンシュワイク普通医学校" SPOILERS
Medical exchange students between Japan and Germany were a thing in the 19th Century, though as far as I could find they mostly went to Berlin. A famous example is 森鴎外. There's a technical college in Braunschweigh which claims to be the oldest established in Germany.... and a memorandum of understanding and student exchange agreement which was established in October 2024 (talk about foreshadowing...) !"ヷルデマール一世"
There were two kings Waldemar I, one in Danemark, one in sweden, none of which are linked to sorcery"ヘンリー・クラムメルの神霊手書法"
defined in wiktionary as “the act of a spirit making words appear out of nothing”, also known as “direct spirit writing”. Wikipedia refers to psychography but pneumography should appear without any human actually doing the writing. I couldn’t find any Henry Crummel linked with this
"加勒底亜五芒星招妖術"
Chaldean magic, including use of magic circles, heavily influenced european medieval magic
The ancient Greeks considered Zoroaster, the Chaldean, to be the father of magic. Considering how knowledge from antiquity came to be known, a latin manuscript referencing greek beliefs/knowledge about chaldean magic makes sense
"元来ウイチグスという人は、亜剌比亜・希臘の科学を呼称したシルヴェスター二世十三使徒の一人なんだ"
This references Pope Sylvester II who did introduce arabic mathematics and greek and arabic sciences to the west. Because of his vast knowledge, he was posthumously accused of sorcery. But there never was any thing about his having 13 disciples, or even any.
ボッカネグロの築城術やヴォーバンの攻城法"
Sébastien le Pestre de Vauban was a french military engineer, famous for establishing fortified cities, and also writing about siege warfare technque. I couldn’t find any mention of a military or construction engineer named Boccanegro.
"デイやクロウサアの魔鏡術"
John Dee was an elisabethan occultist (among other things). he was, at some point in his life, interested in scrying; among his possession, an obisidian mirror, thought to be an Aztec occult artefact, is now at the British Museum
Dee was active in Eastern Europe at some poitnin his life, but I couldn’t find any reference to a magician names Krauser/Krausa/Kraus. There are germanic reference to mirror magic and science at roughly the same time, but the magician (Heinrich Cornelius Agrippa) and the scientist (Athanasius Kircher) have different names.
"カリオストロ"
Giuseppe Bassamo, also known as Count Alessandro Cagliostro was a famous mage and alchemist in 18th century Europe
"ボッチゲル"
Johann Friedrich Böttger was a german alchemist from the 17th century, mainly famous for creating hard-paste porcelain
"ホーヘンハイム"
Philippus Aureolus Theophrastus Bombastus von Hohenheim, better known as Paracelsus was a swiss thologian, physician and alchemist. Of course, name-dropping Paracelsus would have been too easy, better go with Hohenheim…
"グラハム"
Might be James Graham, 19th century proponent of electrical cure and pioneer sexologist, because the link between magic and medicine exists in his works, but I don’t think anyone can be sure…
"猶太秘釈義法からは、四百二十の暗号がつくれると云うけれども"
I’ve found several references to the number 420 in Gematria, though I must admit I don’t understand half of them, even in my native langage, to Strong’s Concordance in which 420 refers to a name meaning “God has known”, and also to some angel numbers on various forums. Apparently, 420 is also code for smoking marijuana, though I highly doubt this is what Oguri had in mind…
"小島郷療養所に於いて和蘭軍医メールデルフォルト"
Pompe van Meerdervort introduced western medical knowledge in Japan and founded the Nagasaki Kojima teaching hospital
"地域はサヴルーズ谷を模し、本館はテレーズの生家トレヴィーユ荘の城館を写し"
The vallée de la Savoureuse does indeed run not too far from the city of Besançon. Trévise is a common name, and a Château de Trévise a plausible invention
"寛永寺"
"頭蓋鱗様部及顳顬窩畸形者の犯罪素質遺伝説"
Reference to phrenology
"路易朝末期の格檣襞服"
This is probably the kind of dress that the mannequin was wearing
"小城魚太郎"
Not a writer of crime novels but the pseudonym of a real-life critique of japanese detective novems, Nakajima Kawataro
"グブラー痲痺"
This probably refers to Millard-Gubler Syndrome though this is not hereditary, and some symptomes, including hemiplegia, are missing. Of course, if they weren’t, this couldn’t have been mistaken for a curse…
"コペッキイ"
The Kopecky family is indeed an historical puppetry family from Bohemia, but more as performers than as puppet-makers
"その昔シュツウツィンゲンの城苑に於て、マンハイム選挙侯カアル・テオドルが、仮面をつけた六人の楽師を養成したと云う一事に尽きている"
Karl Theodor von der Pfalz was indeed a patron of the art, and organised, among other things, concerts at his Mannheim and Schwetzingen palaces
