Adolf Schulten obsession with Spain remained a mystery. Why this German historian spent most of his life in Spain, studying, publishing and, eventually, on site excavation of archaeological sites. As other pioneers of Archaeology in early 20th century, Schulten expected to find his own private Troy in Spain: Tartessos was the myth where he placed the origin of Western Civilization, even before Greece, to be placed in South Spain. The last expert interviewed in the film, José María Blázquez, explains some details of Schulten's private life and thinking, and in particular questions about the fact of Schulten as a young student traveling to Spain as some sort of "call", not having any particular knowledge about the destination of his longings.
Obsessed with his discovery of Tartessos, Schulten took many non-ethical or professional decisions, such as erasing any name of other historians or scientists in his own articles or reports. First he pretended having discovered the site of Numancia in the very first day of excavation (this archaeological site being a Spanish landmark from Ancient times) and later failed to find Tartessos remnants at Doñana National Park. But this did not refrain him from writing a book about the "discovery" that would become a best-seller, even if published a year before the archaeological campaigns.
Even if critical with Schulten's methods and the official support that he got from Franco's government (Schulten's ideas became official in school books and universities during the four decades of Spanish dictatorship) most experts in the film tend to understand Schulten as a "man of his time", and justify his way of thinking as a sample of the spirit of the 1920s, a blend of nationalism, longing for lost paradises and search of chimeric kingdoms to be the origin of Western civilization.
After producing this film, the same team has approached one of the characters depicted: Jorge Bonsor in a new film: El Gran Tour de Jorge Bonsor (2017) specifically focused on this pioneer of Archaeology that shared with Schulten the passion and campaigns in South Spain. The new film does not mention the search of Tartessos, but other sites that Bonsor excavated and prepared for visits and public knowledge.
