Is this θερίδδειν somehow a Bœotian pronunciation of something else than just θερίζειν? The meaning “harvest” seems out of place here.
The broader context can be read here
No it’s just the “Boeotian” rendering of Attic θερίζειν, however problematic the imagery might seem.
I have some ideas about how μέλλω θερίειν might work on its own, but together with συνθέριζε definitely complicates the possibilities.
Given that the trigger happy censorial policy on Textkit curtailed my other recent discussion before it was never able to fully explore the available physical imagery of pottery binding, let alone the metaphoric imagery of binding up a person like pottery that underpins about 30 lines and moved it into the Academy, I suggest not following through with a discussion of the imagery that (συν)θερίζειν invokes. It seems that I am too used to the freedom of speech and expression that we enjoy in China.
K.I.S.S., because superficialities are never offensive or challenging.
