(IAU Directions) BABBAGE.--A still larger enclosed area, adjoining South on the W., and containing a considerable ring-plain near its E. border. It is a fine telescopic object at sunrise, the interior being crossed by a number of transverse markings representing ridges. These are very similar in character (but much coarser) to those found on the floor of J.F.W. Herschel. The curious detail on the W. wall is also worth examination at this phase.

Nomenclature
- Named for Charles Babbage (December 26, 1791 – October 18, 1871) was an English mathematician, philosopher, mechanical engineer and (proto-) computer scientist who originated the idea of a programmable computer. Parts of his uncompleted mechanisms are on display in the London Science Museum. In 1991, working from Babbage's original plans, a difference engine was completed, and functioned perfectly. Built to tolerances achievable in the 19th century, the finished engine indicated that Babbage's machine would have worked. Nine years later, the Science Museum completed the printer Babbage had designed for the difference engine; it featured astonishing complexity for a 19th century device.
- The name was introduced by W. R. Birt in 1862-3.
- This feature is Catalog number 1707 in Mary Blagg's Collated List, where it is noted as being named only in Neison, 1876.
- The name (attributed to Birt) was added to the IAU nomenclature in Named Lunar Formations.
