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.

Boethius is a crater on the planet Mercury. It was named after Anicius Manlius Severinus Boethius, the Roman philosopher, by the IAU in 1976. The crater was first imaged by Mariner 10 in 1974.

Michelangelo is a 230 km diameter impact basin in the Michelangelo quadrangle of Mercury, which is named after this crater. The crater itself was named by the IAU in 1979 after the Italian painter, sculptor and architect Michelangelo.

Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976. It has a prominent and nearly continuous inner ring whose diameter measures about half that of the outer ring. It is one of 110 peak ring basins on Mercury. Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age.

Izquierdo is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2009, for the Mexican painter María Izquierdo. The floor of Izquierdo is smooth, the result of having been partially filled with volcanic lava. Circular outlines of the rims of “ghost craters” – smaller, older craters that have been largely buried by the lavas that infilled the basin – are visible in a few places on Izquierdo's floor. The remnants of a buried inner ring are also barely discernible in spots, and it is one of 110 peak ring basins on Mercury. There have been more recent impacts into the floor of Izquierdo, resulting in some small, sharply defined craters.

Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by the Mariner 10 spacecraft. It has a prominent peak ring, and it is one of 110 peak ring basins on Mercury. The crater floor is covered by the smooth plains material. The crater displays an arcuate collapse feature along the northeastern peak ring. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 38 × 12 km. Such a feature may have resulted from collapse of a magma chamber underlying the central peak ring complex of the crater. The collapse feature is an analog of Earth's volcanic calderas. Scarlatti is thought to have the same age as the Caloris basin.
