Introduction: The Epistles of Heraclitus (p. 22)
This introduction is laying the scholarly and chronological context for the following letters.  While there are only 9, we’re still looking at multiple authors, at least two possibly more.

The fact that scholars were divided as to the Cynico-Stoic nature of the letters versus a Jewish authorship is interesting.  Heraclitus is an interesting figure, almost a zen poet of the west.  Reading his fragments is a very different experience than reading a Stoic treatise, for instance.

This is part of the Cynic Epistles Reading Plan.
