• This paper deals with the origin of the hundred-year old theory of tierras bajas and tierras altas, focusing on the description of vowel weakening within that theory developed in 1921 by Henríquez Ureña. I argue that the early conception of vowel weakening and its dialectal distribution has strongly influenced the kind of research we have been conducting about this phonetic feature to this day. The aim of this study therefore, is to sharpen our understanding of the former zeitgeist of research and to stimulate further big data-based studies onThis paper deals with the origin of the hundred-year old theory of tierras bajas and tierras altas, focusing on the description of vowel weakening within that theory developed in 1921 by Henríquez Ureña.
