We offer an overview of the geometric studies of the russian mathematician N.I. Lobachevski (1792?1856), which culminated with the discovery of the hyperbolic geometry. We analize the role of the V Postulate in the euclidean geometry and the ways some mathematicians tried to prove it. We also examine the foundations of the new geometry and some of its relations with physics and philosophy.En ocasión del segundo centenario del nacimiento del ilustre matemático ruso N.I.Lobachevski (1792?1856), se presenta una visión global de su trabajo geométrico, que culminó con el descubrimiento de la geometría hiperbólica. Se analiza el rol del V Postulado en la geometría euclídea y los primeros intentos por demostrarlo, realizados hasta el siglo XIX. Se...
