Is there any interrelation between finance and letter? Could you believe that the original letter was created by the necessity of the finance?
William Goetzmann alleged in his book " Money change everything" that finance played an important role in the mesopotamia civilization which is one of first civilizations in the human history.
Finance is alleged to related first city, language, law, contract, methematics, etc.
Further, he also told that the original form of blockchain was created around 5,000 years ago. His explanation is quite interesting. If both parties agree to deliver 5 sheeps in future, they put a five pieces into a clay ball which was signed by both parties and blocked by rolling to cover the ball completely. Such tool (which is called a bula) was founded, and it means that the ball(contract record) lasted for 5,000 years. It is quite amazing.
Further, finance demands a calculate and prove through mathematics, and eventually contributed the development of the mathematics mechanism.
His allegations drive us to pay a special attention to the history of finance and its story will be quite interesting.
