This time, the story of Anjin Miura. What is the relationship between Anjin Miura, geometry, and Ieyasu Tokugawa?

William Adams, who has a Japanese name that combines "Miura" derived from the territory of Yokosuka worshiped by Ieyasu Tokugawa, and "Anhori" (a pilot) derived from monitoring the magnet as a pilot, is an Englishman. How many languages did you interact with Japanese people? Since I lived in Japan for many years, I think I could understand some Japanese, but there is no mention that I gave English instruction to Japanese people, so it is not English. It is expected that he interacted mainly with the "Portuguese" he made. For example, when John Seiris, commander of the East India Company, came to Japan, it is expected that a relay interpreter between English and Portuguese and Japanese was performed across a Portuguese interpreter.

I learned him some points of jeometry, and understanding of the art of mathmaties. Here he is Ieyasu. Grammatically, the underlined part appears to be an error, but it is not an error. (I wrote it with a pile of light Yasumura's Don't worry! I'm wearing., but it may not be transmitted.) Learn from the time of Shakespeare means "taught" when there is an indirect purpose. I taught him some points of geometry, and understanding of the art of mathematics. Ieyasu learned geometry from Anjin Miura, didn't he?

If this is true, Ieyasu will be the first Japanese to do geometry.
