This is a survey of results of existence and uniqueness to the Navier-Stokes equations $\frac{\partial v}{\partial t}+(v\cdot\nabla)v-\nu\Delta v+\nabla p=f,\quad \text{div }v=0, \qquad v(x,0)=v_0(x).$ Results obtained in different functional spaces, especially in Besov spaces, are discussed. The time period of reviewed works runs from 1930 (pioneering papers of J. Leray) up to 2000 (R. Temam). The reader can find the references of many interesting but rarely cited works. Linguistic and philosophical excursions revive the text of the survey.
