Just because we cannot see it, does not mean it cannot exist. Non-intrusive technology using photometric techniques has aided a team of researchers in uncovering four new sets of designs painted on the walls of Spanish caves thousands of years ago. The oldest of the paintings is nearly 30,000 years old –one of the oldest examples of prehistoric art found to date. The discoveries open a world of possibilities in identifying and analyzing paleolithic cave art.
Cantabria is the home to one of the highest known concentrations of prehistoric cave paintings in the world. Project leader, Spanish prehistorian Roberto Ontañón explained to El País : “It was a very good place to live during the Ice Age. The Cantabrian Sea warmed up the climate and vast herds of wild animals such as horses passed through that narrow strip between the sea and the mountains.”
