"Book of Wisdom" is the 9th chapter of The Mystic Archives of Dantalian manga. Its story involving the Book of Wisdom continues in Chapter 11.

Kamilla shows up at the Disward estate and talks to Hugh and Dalian about how Mildred's students obtained absolute knowledge after reading a book.[1]


De Sapientia is a book that gives absolute wisdom to its reader. Some kids are shown in a classroom. They have the book described on a table. They are discussing about complicated subjects. Then, the kids start to wonder if they should entrust the world to the foolish adults. With De Sapientia, they have the power to change the world.

Wise children (1)

The Book of Wisdom was read by Mildred's students.

Hugh is outside, reading the news, resting from doing maintenance on his car. Dalian appears, affirming that she is hungry, even after breakfast. She stars yelling after knowing there are only some sandwiches left. However, Kamilla brings snacks, interrupting the fight.

During the early tea break, Kamilla asks if there is a book that can make you brighter. She believes that a book like that would exist among Wesley’s collection. She explains how Mildred, from the Dewar family, had obtained a black book.

Mildred is shown having problems to deal with her students, since they appear to be more intelligent than her. They even learned how to talk in Latin.

According to Kamilla, Mildred even left her house. Later, Dalian confirms that Kamilla was talking about a Phantom Book. A person that reads the Book of Wisdom can dominate or destroy worlds. Hugh wants to collect the book. Dalian, however, affirms that they should leave it alone. The Book of Wisdom was the only Phantom Book Wesley didn’t collect.

Wise children (2)

Mildred's selfish plan fails.

Mildred is trying to deal with her students. She sold her estate to provide research fund for the brilliant kids. She carries a briefcase full of money. Her intention is using the kids to make more money. However, they don’t want to use their powers. Control mankind would be tiresome and would have little return. Their chances of success would be low. They want to live without working. They have strange, vacant eyes.

Meanwhile, at the Disward estate, Dalian uses the tic-tac-toe game as an analogy. She affirms that adults stop playing the game because they recognize the logic behind it. Wesley didn’t collect the Book of Wisdom because it’s a failed Phantom Book. Those who read it become geniuses, but end up doing nothing. With the power of foresight, an intelligent person will give up, rather than give it a try. Hugh affirms that brilliant figures are not the wise ones, but those who never give up. Dalian is satisfied with Hugh's wisdom.

Rasiel shows up, levitating into the classroom during a full moon night. According to her, she was called by the Book of Wisdom. She lets the Phantom Book sleep inside her. Outside, she meets with the Professor. He notices how Rasiel is happy. Rasiel is satisfied because she will finally meet Dalian again.[1]

  • The chalkboard in the classroom shows works by Italian Leonardo da Vinci[1]: his designs for a fighting vehicle and a flying machine and the Vitruvian Man drawing. The first page of the chapter, after the title, shows part of one of his drawings in Anatomical studies of the shoulder, from 1510.[3] The same scribbles appear in Chapter 11.[4]
  • When Hugh first appears in the chapter, he's reading news about mafia members having drug-induced hallucinations and committing suicide last month,[1] a reference to the events of The Perfumer, where Fiona Famenias destroys the Padauk Company.[5] The police suspects a man and a woman who were witnessed near the crime scene.[1]
  • Dalian mentions the tic-tac-toe paper-and-pencil game to explain why the Book of Wisdom is harmless. The wise children won't try to control the world, since they know the consequences of their actions. Similarly, tic-tac-toe is a solved game, meaning that the outcome can be predicted. Players soon discover that the best play from both parties leads to a draw. Hence, tic-tac-toe is most often played by young children, who often have not yet discovered the optimal strategy.[1][7]
