In 1572, Bombelli published in his treatise L’Algebra (Bombelli 1572) an Italian translation of a good part of the problems in Diophantus’ work. Bombelli had made a first manuscript of his Algebra and, before publishing it, he had access through Antonio Maria Pazzi, a professor of mathematics in Rome, to the manuscripts on Diophantus’ work located at the Vatican Library.
Rafael Bombelli (baptised on 20 January 1526; died 1572) was an Italian mathematician. Born in Bologna, he is the author of a treatise on algebra and is a central figure in the understanding of imaginary numbers.
Rafael Bombelli was born in 1526 in Bologna. His father, Antonio Mazzoli, changed his name to Bombelli in order to avoid the reputation of the Mazzoli family. The Mazzoli family had once been very powerful and influential in Bologna. This all changed when Pope Julius II came to power. In 1506, the ruling family, the Bentivoglios, were exiled.
L'Algebra by Rafael Bombelli: frontispiece of the Bologna edition of 1579. Bombelli's great insight was simply to treat − 1 as a number and to operate with it following some specific arithmetic rules (the same kind of rules that we use nowadays). Thus he discovered that. 2 + − 121 3 = 2 + − 1 and 2 − − 121 3 = 2 − − 1.
Unos años más después del descubrimiento de la fórmula de Cardano, el ingeniero y arquitecto italiano Rafael Bombelli (1526-1572) reconoció que había algo extraño y paradójico acerca de esta fórmula. Él consideró la ecuación (7) x 3 = 15 x + 4 y, con un poco de reflexión, puedes ver que x = 4 es una solución.

Born in Bologna, he is the author of a treatise on algebra and is a central figure in the understanding of imaginary numbers. He was the one who finally managed to address the problem with imaginary numbers.
