We face this work explaining semiotics and showing how it can be applied to religious symbols/Relics (of the Catholic faith) to those who know little or nothing on the subject with a certain amount of apprehension.There is e a large and rapid expanding literature in the subject and that many of the writings of Semioticians are difficult to understand and highly technical. So our mission is quite challenging: Not only are we to explain the fundamental notions or elements of semiotics, but we are also to apply them to religious symbols/relics. It is a large undertaking, but we think it can be done. The price we must pay involves a certain amount of simplification and narrowness of focus.We are going to explain the basics of semiotics and discuss some sample applications. We hope that after reading the various chapters and the annotated bibliography provided, those interested in semiotics will probe more deeply into it at their own convenience.
