  Alonso de la Veracruz conducted a physical study of image, regarding the
activities of Soul in which image is produced, as organic operations. This
research was particularly important since, at that time, image was
systematically used to propagate the European culture in New Spain. Besides,
Alonso uses the visual radius to criticize the magical attitude popular in
Renaissance, denying the far sight and fascinations abilities attributed to
witches. Also, Alonso Guti\'errez applies the Aristotelian physics to deny the
healing powers attributed to the kings of France and England, secularizing this
way the gallic monarchies, and several other superstitions of that time. This
way, the physics of image developed by Alonso can be considered as close to the
rationalism of Descartes inasmuch as Guti\'errez criticizes the magical view of
Renaissance and introduces geometrical elements to elucidate physical problems.
