    Re: The Star of Bethlehem and Navigation

    Ok, Geoffrey, that makes things fairly clear: no chance for a possible
    "navigational" approach.
    You wrote: "The ancients did not have clocks as we know them."
    The time is one thing. I guess that also the dates of the observations
    may not always be clear and could be off by a day or so. In those days
    the beginning of the month was determined by the first visibiltiy of
    the crescent moon as it is still done for the Islamic calender. There
    exist these days - in the time of computers - various propositions on
    how this first visibilty can be calculated for a given location. Does
    the paper you mentioned indicate how they handled this problem?
