## Historical Note on *Traité du Triangle Arithmétique*

Blaise Pascal wrote this book in $1653$, but did not publish it until $1665$, as he had turned his attention away from mathematics in order to concentrate on religion.

Hence there exists some confusion in published sources as to the year of publication.

Some give it as $1663$, while others give it as $1655$.
