^Schmitt, Rüdiger (15 December 1995). "DRANGIANA or Zarangiana; territory around Lake Hāmūn and the Helmand river in modern Sīstān". Encyclopædia Iranica. "The name of the country and its inhabitants is first attested as Old Persian z-r-k (i.e., Zranka)in the great Bīsotūn (q.v. iii) inscription of Darius I (q.v.; col. I l. 16), apparently the original name. This form is reflected in the Elamite (Sir-ra-an-qa and variants), Babylonian (Za-ra-an-ga), and Egyptian (srng or srnḳ) versions of the Achaemenid royal inscriptions, as well as in Greek Zarángai, Zarangaîoi, Zarangianḗ (Arrian; Isidore of Charax), and Sarángai (Herodotus) and in Latin Zarangae (Pliny). Instead of this original form, characterized by non-Persian z (perhaps from proto-IE. palatal *γ or *γh), in some Greek sources (chiefly those dependent upon the historians of Alexander the Great, q.v.) the perhaps hypercorrect Persianized variant (cf. Belardi,p. 183) with initial d-, *Dranka (or even *Dranga?), reflected in Greek Drángai, Drangḗ, Drangēnḗ, Drangi(a)nḗ (Ctesias; Polybius; Strabo; Diodorus; Ptolemy; Arrian; Stephanus Byzantius) and Latin Drangae, Drangiana, Drangiani (Curtius Rufus; Pliny; Ammianus Marcellinus; Justin) or Drancaeus (Valerius Flaccus, Argonautica 6.106, 6.507) occurs."
