Polygnotus is a crater on Mercury, named by the IAU in 1976, after ancient Greek painter Polygnotus.[1] The crater was first imaged by Mariner 10 in 1974.[2]
Polygnotus has a central peak ring which is embayed with smooth plains material, which is very different in texture from the surrounding terrain.[3] It is one of 110 peak ring basins on Mercury.[4]
Boethius crater is west of Polygnotus. Tansen is to the northwest, and Motonobu is to the east.
