An Analysis of Hypertextuality on Double-headed Eagle in the Buwayhid and the Sassanid era

The motif of the double-headed eagle which is associated with the famous fabrics of Al-Buwayh is a rare, unique, and cryptic motif in the art of different historical periods of Iran that has many unexplored aspects. This motif can also be seen on a metal plate belonging to the Sassanid era, before appearing on the textiles of this period. This evidence has not been covered by any research before the present study. Considering the many influences of the Buwayhid dynasty from the Sassanid in various fields such as politics and culture, as well as the numerous derivations of this dynasty from Sassanid art, this study introduces the mentioned motif in the Sassanid era as a pretext for the Buwayhid era. The purpose of this study is to investigate the relationship between the two texts (the pretext in the Sassanid era and the Hypertext in the Buwayhid period) and to reveal the types of hypertext typology. The present article tries to give a clear answer to these questions: How can the connection between this motif in the period of Al-Buwayh and its predecessor be explained? What changes have taken place in the process of adaptation of this role from the Sassanid era by Al-Buwayh? This research has been done by descriptive-analytical and comparative methods and applies Gerard Genet's theory of Transtextuality. The findings of this study indicate that with the combination of written and visual signs, the relationship is transposition and by simultaneous thematic development and increase in stylistic issues, Development has taken place. The permutation by the artist of the Buwayhid period shows the effort to harmonize and reconcile Islamic beliefs and the cultural heritage of antiquity.
