Arrian

Arrian of Nicomedia (; Greek: Ἀρριανός Arrianos; Latin: Lucius Flavius Arrianus; c. 86/89 – c. after 146/160 AD) was a Greek historian, public servant, military commander and philosopher of the Roman period.The Anabasis of Alexander by Arrian is considered the best source on the campaigns of Alexander the Great. However, more recently, even though modern scholars have generally preferred Arrian to other extant primary sources, this attitude towards Arrian is beginning to change in the light of studies into Arrian's method.
