Ars Magna
The Ars magna is among the most influential books of algebra. Not only does it present for the first time in history the long-awaited solution of the cubic (and even quartic) equation, but also considers many matters of interest: The connection of roots and coefficients, an idea picked up by Vieta, the start of a systematic study of algebraic equations, the appearance of negative and even imaginary and complex numbers - all these issues proved to be fertile ground for the further development of algebra. The Ars magna stands for the first major occidental contribution to the field.
