About this source

What it is

The Anabasis of Alexander is a history in seven books written by the Greek author Arrian of Nicomedia in the second century AD, long after Alexander's death. Arrian based his account on now-lost writings by two men who had been with Alexander: the general Ptolemy and a military engineer named Aristobulus.

Why it matters

This is considered the most complete and reliable surviving account of Alexander's conquest of the Persian Empire, covering his battles, sieges, and controversies such as the killing of Cleitus. Because Arrian relied on sources written by people close to Alexander, including Ptolemy, who later became a king himself and may have shaped the story to flatter his own role, the text reveals as much about how Alexander's companions wanted him remembered as about Alexander himself.

Look closer

  • What does it mean that our best source on Alexander was written centuries after he died?
  • Why do you think Arrian felt the need to correct other popular stories about Alexander?
