Brown in 1892 does not mention Mas-d'Azil. He refers to the "transition or 'Mesolithic' forms" but to him these are "rough hewn axes chipped over the entire surface" mentioned by Evans as the earliest of the Neolithic. Where Piette believed he had discovered something new, Brown wanted to break out known tools considered Neolithic. Sir John Evans never changed his mind, giving rise to a dichotomous view of the Mesolithic and a multiplication of confusing terms. On the continent, all seemed settled: there was a distinct Mesolithic with its own tools and both tools and customs were transitional to the Neolithic. Then in 1910, the Swedish archaeologist, Knut Stjerna, addressed another problem of the Three-Age System: although a culture was predominantly classified as one period, it might contain material that was the same as or like that of another. His example was the Gallery grave Period of Scandinavia. It was not uniformly Neolithic, but contained some objects of bronze and more importantly to him three different subcultures. One of these "civilisations" (sub-cultures) located in the north and east of Scandinavia was rather different, featuring but few gallery graves, using instead stone-lined pit graves containing implements of bone, such as harpoon and javelin heads. He observed that they "persisted during the recent Paleolithic period and also during the Protoneolithic." Here he had used a new term, "Protoneolithic", which was according to him to be applied to the Danish kitchen-middens. Stjerna also said that the eastern culture "is attached to the Paleolithic civilization ("se trouve rattachée à la civilisation paléolithique")." However, it was not intermediary and of its intermediates he said "we cannot discuss them here ("nous ne pouvons pas examiner ici")." This "attached" and non-transitional culture he chose to call the Epipaleolithic, defining it as follows: With Epipaleolithic I mean the period during the early days that followed the age of the reindeer, the one that retained Paleolithic customs. This period has two stages in Scandinavia, that of Maglemose and that of Kunda. ("Par époque épipaléolithique j'entends la période qui, pendant les premiers temps qui ont suivi l'âge du Renne, conserve les coutumes paléolithiques.
