Let me state up front that I find it extremely hard to believe that a bipedal primate, unknown to science, could exist up to the present time in a narrow stretch of mountains between two heavily populated countries, such as France and Spain. Then again, I held the same view about the Australian yowie, until the sheer bulk of evidence became too large to ignore, for evidence which would be unimpressive individually can become very strong in the aggregate. We must therefore follow the trail wherever it leads us, and at least record every item of evidence as it turns up.
Some months ago, when I published an article on the legendary "wild man of the Pyrenees", Javier Resines kindly informed me about various articles on the same matter on his own Spanish language blog. So, for those whose Spanish is limited, I shall provide a translation of his article of 30 March 2012. As explained, the closest town to the event was Irún (43° 21'N, 47° 20' W), an ancient Basque city close to the sea and to the French border.
