([/IAU%20Directions IAU Directions]) VLACQ.--A member of a magnificent group of closely associated formations situated on the greatly disturbed area between E. long. 30 deg. and 45 deg. and S. lat. 50 deg. and 60 deg. It is 57 miles in diameter, and is enclosed by terraced walls, rising on the E. about 8,000 feet, and on the W. more than 10,000 feet above the floor. They are broken on the S. by a fine crater.

Nomenclature

  • Named for Adriaan Vlacq (1600-1667), a Dutch book publisher and mathematician. Vlacq published a table of Henry Briggs' logarithms from 1 to 100,000 to 10 decimal places in 1628 in his Arithmetica logarithmica.
  • According to [/Whitaker Whitaker] (p. 214), this feature was labeled [/Pitiscus Pitiscus] on [/Riccioli Riccioli]'s map. The usage of the name Vlacq for the present feature was introduced by [/M%C3%A4dler Mädler], although the same person had been honored earlier by [/Langrenus Van Langren] (with the spelling Vlacci and the name assigned to the feature now known as [/Capella Capella]) ([/Whitaker Whitaker], pp. 219-220).
