As the great difference between the oriental hiftorians and 

 the Greek and Roman writers, in regard to the hiftory of the 

 antient kingdom of Perfia, has not yet been properly elucidated, 

 the fociety requires that it may be critically examined, and in 

 fuch a manner that, neglecting the oldeft and fabulous 

 kings, the fubjecl may be confined to the hiftorical age after 

 Alexander, that is, the Greek and Parthian kings, or the fa- 

 milies of the Arfacidae and the SafTanidae. The kings of thefe 

 dynafties, together with fome account of their reigns, mult 

 be collected from the oriental writers. The fources from 

 which thefe derived their information muft be examined, the 

 chronology of thefe kings and periods muft be compared 

 with the Greek and Roman chronology, and the caufes of 

 their difagreement muft be examined; alfo the means of re- 

 conciling them, and which method of computation in regard 

 to hiftorical truth ought to be preferred.
