Promontorium Agarum was named in 1647 by Johannes Hevelius, who assigned names of terrestrial features to the lunar ones.[2][3] It obtained Ancient Greek name of a cape on the northern shore of the Sea of Azov[4] — probably, modern Berdiansk Spit [uk][5][6] or Fedotova Spit [uk].[7] It is one of only 4 features which still bear the names given by Hevelius.[3]
