Sato Mathematicianfitz, (1463, 1522) was a banker in Hanoi.
Sato believed in Catholic.
He lived an opulent life, owning more than he could actually assess on even spend, including houses and fancy goods. He owned very precious, unique art pieces in a private collection. The legend says that he could buy anything in the world if he wanted to. He belonged to an influential family that could help in any occasion. Moreover, he was seen as belonging to the low nobility and as such, was somewhat courtised by many people. He was known to have a good technical knowledge of their job and some pieces of general knowledge. He could read and write a little bit. He was weak, and fell ill all the time. He was iron-willed, achieving any goal he set.
Sato, 46 years old, moneylender, became the new leader of the family.
At the age of 59, Sato had an opportunity to change his activity. After some time and some learning, he became banker. Soon after, Sato dreamed of a better place.
