Nahualism is one of the most persistent and widespread concepts in Mesoamerican spirituality. Present since the Olmec formative period and documented to this day in indigenous communities in Mexico and Guatemala, it describes the belief that certain individuals share their essence with a specific animal—their nahual—so that what happens to one affects the other, and both act in the world in a coordinated way. It is not a costume or a complete metamorphosis: it is a double, simultaneous identity that exists in two planes at once. The man in this mural does not imitate the jaguar, nor does he become one: he is himself and the jaguar at the same time, and that condition is not exceptional but the definition of what he is. That this identity is expressed visually through the animal's skin—worn as a garment, not as a disguise—may have been a precise iconographic decision: the skin does not conceal the man but completes him, adding to his human body the animal dimension that is already his. This mural is one of the oldest and most explicit representations of that concept in known Mesoamerican art.
