Is There Any Sign That They Thought They Were Talking To?

Do you think we can say very much about who the presocratics thought they were talking to? I mean, xenophanes may have been performing at banquets at least some of the time. But for example, heraclitus, or even the poem of parmenides, or, for that matter, the milesians, do you think there is any sign that could tell us who they weretalking to and who they expected to be able to read their books? We just have to gas about that. Well, that likes so much to do wih priestcratics. It is mostly guess work, i think.
