Pascal, although he is attributed with being the first one to publish
the information known about the triangle in his treatise, Trait´e du triangle
arithm´etique. The numbers originally arose from Indian studies
of combinatorics and the Greeks interest in figurate numbers. These
numbers were continually discussed by Islamic mathematicians during
the 10th century and in the 11th century by a Persian poet named
Omar Khayyam. They were also seen in China during the 13th century.
The Pascal’s triangle was officially published in Pascal’s treatise
soon after his death in 1665.
