    In all cases of such events in dispute, we have
these considerations:

a) Is there evidence that there was any such event?

    Baillie's tree-rings, the study of chronicles
    and records (tip of hat to E. P.), and more.
    So, yes.

b) what are the possible causes of the event?

    I discussed all the proposed causes at some length,
pro's, con's, problems, virtues, of each:

    1. Napier & Clube's Encke protocomet and remnant
    2. Baillie's single impact theory, not that different a theory
        from N&C's.
    3. A previous earlier and bigger eruption of Krakatoa
        did occur but cannot be dated to within centuries of
        530-540 AD with any precision.
    4. And, the possibility of a dust event as the cause and
        how it could explain the presence of some evidences
        and the lack of others, a possibility I raised.

    We were discussing The Problem. We were, I thought,
looking for a non-contradictory explanation. The thread sprang
from an inquiry from a List Member, who asked "Could This
Have Happened?" True, Mark had heard about it in the
context of the single impact theory.

    I suppose you could insist that the discussion on The List
be narrowly limited to that SOLE aspect of the problem of the
534 AD event, to that aspect only, and that any other aspect
of the problem be banned from the discussion, neither should
the problem in any other, fuller perspective be raised,
discussed nor mentioned by anybody.

    However, I doubt anyone would pay any attention.

    Frankly, I cannot see why they should. What advantage
would there would be in that approach? It is The Problem
itself, in its entirety, that we are interested in, is it not?
