"The Kiss", a 12,000-year-old rock painting at Pedra Furada in Brazil
The prehistoric inhabitants of what we now call Serra da Capivara, Piauí, Brazil, painted two human figures on stone that today are known as The Kiss ("O Beijo" in Portuguese) (Guidon, 1992; Lourdeau, 2019) (Figure 1). As the intimate and sincere expression of affection between people, the simple kiss puts us on an advanced level of civilization, as individuals who are capable of appreciating and portraying such a human gesture with delicacy. Nothing could be further than the image of the prehistoric troglodyte man who drags his woman by the hair with one hand and holds a club in the other. The Kiss of Serra da Capivara is almost symmetrical, arms and hands are not needed. A less romantic interpretation, but by no means less humanistic, is that the figure on the right leans to place chewed food into the mouth of a child or elderly person.
