This book deals with the documentation and interpretation of the rock sites located in La Mancha center (Spain), from the detailed study of the symbols that have been engraved in the rock. These sites, from historical times, can provide valuable information for the study of the mentalities and beliefs of the popular classes during the Modern Age, strongly influenced by the atmosphere created after the Counter-Reformation. Crosses, calvaries, orbs, human and animal representations, letters, cup-marks and game boards make up an authentic symbolic universe, of clear Christian roots, whose understanding is possible to achieve even though it requires collaboration between multiple fields of knowledge such as archaeology, theology, numismatics, heraldry, architecture, sculpture, painting... Unfortunately, researchers have paid scant attention to the issue at hand, assuming paradigms that from our point of view should be reviewed, such as the authorship of the petroglyphs or their chrono-cultural affiliation. The study of the rock formations located in La Mancha center can shed light on these and other subjects, providing a good starting point in order to improve the documentation and interpretation of historical rock engravings in other parts of the world.
