Desargues (Moon)

Named after Gérard Desargues - French mathematician, engineer (1593-1662).

Desargues is an ancient lunar crater that is located near the northern limb , on the western hemisphere. It lies nearly due south of the crater Pascal, and southeast of Brianchon. The proximity of this crater to the limb means that it appears highly elongated due to foreshortening, and it is difficult to discern details from the Earth. This formation has been significantly eroded and degraded with the passage of time, leaving a low, irregular rim that has been reshaped by subsequent impacts. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
