1931 L. S. B. Leakey Stone Age Cultures Kenya Colony xi. 243 In attempting to discuss the relation of the Gumban to cultures in other parts of the world..it should be noted here that the name of this culture has been derived from a Kikuyu term which is applied to-day primarily to a semi-mythical race of small people... In using the word for this culture, I am not referring to this, its primary meaning, but to its present more usual meaning, that is in reference to any people who preceded the Kikuyu. From the moment that I first started excavations, old Kikuyus who visited the camp used to talk of my ‘search for the Gumba’, and when thinking of a name for this comparatively recent culture the word Gumban seemed to be not inappropriate.
