#   Speculation is that the two inner circles are one paragraph since
#   they share the single line marker at 09:05, and the two outermost
#   are another paragraph since they share the double line marker at
#   10:00.
#
#   However those lines may be modern guesses.  The aligned gaps 
#   at 12:00 on the two outer rings and at 06:00 on the two inner rings
#   are equally plausible.
