This evocative essay focuses on the encounter of two eminent Men of Mathematics: José Tola Pasquel, Peruvian, and Maurício Matos Peixoto, Brazilian, in November of 1961 in Lima. It glimpses into the local meaning and later mathematical consequences of such apparently random event. Here are discussed its implications for the participation of the author in the starting steps of the Qualitative Theory of Differential Equations, earlier name for Dynamical Systems, as a research activity in Brazil.
