Protagoras is a lunar impact crater that is located on the Mare Frigoris on the northern part of the Moon. To the north-northwest is the slightly larger Archytas crater, and to the southeast is the prominent Aristoteles crater.
The rim of Protagoras is circular and rises above the surrounding flat terrain, although the rim dips down along the southwest edge. The interior floor contains a few light markings but no formations of interest. There is an area of rough terrain just to the east of this crater, but the surroundings are otherwise level with only a few small craters in the vicinity.

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Protagoras crater.
Protagoras was born around 481 BC in Abdera, Thrace in Ancient Greece.
It was Protagoras' teachings that spurred later philosophers such as Plato to search for objective, transcendent guidelines to underlie moral behavior, and the importance of subjectivity is an important theme in modern philosophy.
Protagoras knew that the less appealing argument could hide the best answer, which is why he stated that it was constantly necessary to strengthen the weakest argument.
