Besides its historical, geographical, literary, and social significance, Tarikh Beihaghi, an important Persian literature work, particularly enjoys its writing style. Following Abu Nasr Moshkan’s (Beihaghi’s teacher) prose style, Beihaghi’s prose shares certain characteristics with those of the Samani era. On the other hand, these same features relate the work to technical prose works. Moreover, it owns features that distinguish it from other similar works. Besides archaism, one can see different forms of periphrasis and circumlocution, poetic features, especially allusion and simile, and various influences of Arabic literature, in Beihaghi’s prose. Beihaghi’s styles are more revealed in sentence structures, some transpositions, word coining, using specific allusive statements, and certain poetic images.
