Some considerations on inscription and the necessity of applying the principles and rules of calligraphy in the analysis of inscriptions

Existing approaches to inscriptions tend often to regard various literary aspects, some considerations on the text content, historical importance, and tendency to the past events illustrated in the inscriptions, and this has led to the typology and classification of inscriptions in terms of endowment, decree, memorial, and construction themes, and in another way, the recognition of stuffs and materials.
In the meantime, it has been underestimated the artistic aspects of the inscriptions in terms of high-value calligraphy. An important part of this failing goes back to the lack of fundamentals and methods for the critique of inscriptions based on calligraphic considerations and its principles and rules. Although such principles and rules are regarded as an important source and criterion for understanding beauty, recognizing and analyzing calligraphy works, however this measure has been applied in non-engraving forms, piecewriting ,chalipa, scribing manuscripts, book binding, but neglected in the practice of inscription.
The purpose of this study is to provide theoretical and analytical bases and fundamentals on how to benefit from the principles and rules of calligraphy in inscription from the perspective of calligraphic art. The study is conducted in an analytical and descriptive method based on library studies and field data on inscriptions. Answering to the main question and issue of the research, i.e. how to analyze the inscriptions in terms of the principles and rules of calligraphy, an referring to the treatises and related researches on calligraphy, the findings of the study indicate that It is possible to use the principles and rules contained in the calligraphy treatises, with special considerations on inscription and architectural requirements with some necessary modifications and bearing in mind the degree of adaptation of some of them in the inscription.
The principles of proportion (alignment), composition (coordination), and seat are of more value. And the principles of Safa (succulence) and Shaan (pleasant) and the rule of the theoretical and practical writing are at the next importance. The way of recognition of the style and method as an essential component in the analysis of inscription, given the quality and quantity of inscriptions, is also important. It is obvious that the proposed principles, along with other methods and typologies of inscription studies, can lead to a more systematic understanding of the values of inscriptions, and provide a more fresh perspective for assessment and analysis of  aesthetic aspects of the inscriptions.
