This is a collection and analysis of the comments on the Basque language, its origin, words derived from Basque and other related issues, by several foreign scholars of the 16th and 17th centuries (Jean le Maure, Charles de Bouelles, Hieronymus Megiserus, P. Merula and Joseph J. Scaliger).
The author points out that research on works not yet studied (dictionaries, cosmographies,. etc.) may be of great importance in helping us to know the view of Basque held by foreign authors of the time. This might also bring about the finding of works in Basque that are now considered to be lost.
