Trivia:
An imaginary convoy of lunar explorers, near and on the floor of Harpalus, is seen in an extraordinary painting which was made by Chesley Bonestell, for the magazine Collier's (see: the ninth painting on page Collier's 2 in Fabio Femino's Fantascienza website). - DannyCaes Jan 13, 2008

(IAU Directions) HARPALUS.--A conspicuous ring-plain, about 14 miles in diameter, on the N.W. of Foucault, with a floor sinking 13,000 feet below the surrounding surface. As the cubic contents of the border and glacis are quite inadequate to account for it, we may ask, what has become of the material which presumably once filled this vast depression? Harpalus has a bright central mountain.

Nomenclature
- The name Harpalus has continued unchanged since its original use for this feature on Riccioli's map (Whitaker, p. 212).
- This crater was called Morini by Van Langren.
- According to the IAU Planetary Gazetteer this crater is named for Harpalus (unkn-c. 460 B.C.), a Greek astronomer who made refinements to the luni-solar cycle in the time between Cleostratus and Meton. The original name has sometimes (almost certainly incorrectly) been attributed to a later and more famous Harpalus, who was a colorful friend of Alexander the Great, but with no known astronomical connection. - JimMosher
- Harpalus Lambda (hill east-southeast of Harpalus, north of Foucault), Harpalus Gamma and Harpalus Xi (two hills west-northwest of Harpalus). See Chart 1 in the Times Atlas of the Moon.
