Mare Frigoris is occupying most of these captures, on which are craters such as Aristoteles, Egede, W. Bond, Barrow, Meton, Protagoras, Archytas and Timaeus.
          Archytas (32 km) is an impact crater , which is on the northern edge of Mare Frigoris. To the northwest is the Timaeus (33 km), comparable in size to Archytas, and Protagoras (22 km), which is smaller,in the opposite direction to the southeast.
Archytas's rim has sharp edges and presents aspects of erosion due to subsequent impacts. Outer wall is nearly circular, with a slight passive bulge southeast. The interior is rough, and has a pair of central peaks.
