The Anabasis of Alexander

The Anabasis of Alexander was composed by Arrian of Nicomedia in the second century AD, most probably during the reign of Hadrian. The Anabasis (which survives complete in seven books) is a history of the campaigns of Alexander the Great, specifically his conquest of the Persian Empire between 336 and 323 BC.
Both the unusual title "Anabasis" (literally "a journey up-country from the sea") and the work's seven-book structure reflect Arrian's emulation (in structure, style, and content) of the Greek historian Xenophon, whose own Anabasis in seven books concerned the earlier campaign "up-country" of Cyrus the Younger in 401 BC.

Arrian of Nicomedia  (c. 86/89 – c. after 146/160 AD) was a Greek historian, public servant, military commander, and philosopher of the Roman period.
