In the work of Niels Henrik Abel and Carl Jacobi, the answer was formulated: the resulting integral would involve functions of two complex variables, having four independent periods (i.e. period vectors). This gave the first glimpse of an abelian variety of dimension 2 (an abelian surface): what would now be called the Jacobian of a hyperelliptic curve of genus 2.
