Persia (Parsua) is first mentioned as a country in an inscription of Rammanu Nirari III (WAI, I, plate 35, number 1, l. 8), who boasts of having conquered it and other lands (he reigned from 812 to 783 or from 810 to 781 BC).
LITERATURE.
Besides the main authorities mentioned in the text, we learn much from Spiegel, Die Altper-sischen Keilinschriften, Arrian, Thucydides, Polybius, Strabo, Curtius.
