Callisthenes in the context of "Alexander the Great in legend"

Proxenus of Atarneus (Greek: Πρόξενος ὁ Ἀταρνεύς) is most famous for being Aristotle's guardian after the death of his parents. Proxenus educated Aristotle for a couple of years before sending him to Athens to Plato's Academy. He lived in Atarneus, a city in Asia Minor.

Proxenus had married Aristotle's older sister Arimneste, whereby they had a daughter Hero and a son Nicanor. Hero's own son, Callisthenes, would later become a student and collaborator with his great-uncle Aristotle. Nicanor eventually married Aristotle's daughter, Pythias.

The Alexander Romance is an account of the life and exploits of Alexander the Great. Of uncertain authorship, it has been described as "antiquity's most successful novel". The Romance describes Alexander the Great from his birth, to his succession of the throne of Macedon, his conquests including that of the Persian Empire, and finally his death. Although constructed around a historical core, the romance is mostly fantastical, including many miraculous tales and encounters with mythical creatures such as sirens or centaurs. In this context, the term Romance refers not to the meaning of the word in modern times but in the Old French sense of a novel or roman, a "lengthy prose narrative of a complex and fictional character" (although Alexander's historicity did not deter ancient authors from using this term).

It was widely copied and translated, accruing various legends and fantastical elements at different stages. The original version was composed in Ancient Greek some time before 338 AD, when a Latin translation was made, although the exact date is unknown. Some manuscripts pseudonymously attribute the text's authorship to Alexander's court historian Callisthenes, and so the author is commonly called Pseudo-Callisthenes.

There are numerous surviving ancient Greek and Latin sources on Alexander the Great, king of Macedon, as well as some Asian texts. The five main surviving accounts are by Arrian, Plutarch, Diodorus Siculus, Quintus Curtius Rufus, and Justin. In addition to these five main sources, there is the Metz Epitome, an anonymous late Latin work that narrates Alexander's campaigns from Hyrcania to India. Much is also recounted incidentally by other authors, including Strabo, Athenaeus, Polyaenus, Aelian, and others. Strabo, who gives a summary of Callisthenes, is an important source for Alexander's journey to Siwah.
