Two rare predictable solar eclipse patterns

Two rare patterns of solar eclipses heretofore perhaps not well-known to
many are geographically significant in relation to each other.

One is a pattern that occurs every 1841 years +15 days (672441 days apart)
where a similar eclipse occurs very close to the same lattitude but
displaced longitinally in a consistent, predictable pattern. I read about
this pattern some time ago doing astronomy research. This pattern might not
be that well known since Meeus in "Mathematical Astronomy Morsels"(1979) did
not mention it in a chapter regarding solar eclipses occuring in the same
location though his reference might have been more specific to a certain
geographical point rather than regionally.

But in that regard, another eclipse pattern series occurring between 979-655
BCE also provides some geographic predictability as the eclipses occur in
the exeligmos pattern (54 years 1 month) rising from the South Pole to the
north at 15-degree intervals. Three eclipses in this pattern occurred in
the region of Babylon and Assyria, which would have allowed the third
eclipse in the series (709BCE) to have been predicted by both date and
location. This rare predictable eclipse series might have been the one used
in relation to Thales' predicted eclipse warning to Ionia.

At any rate, when the 1841-year cycle was applied to these eclipses, this
series pattern did occur again between 863 AD - 1187AD. A series of
eclipses rising from the South Pole to the North about 15 degrees apart in
the same general longitudes.

How rare this particular pattern is may take more research to determine, but
it does recur in the 1841-year pattern.

Here are two "very rough" schematics that reflect on the two patterns of
predictable solar eclipses;

These are the modern eclipses from 863AD - 1187 AD:

Here is the matching pattern occuring from 979BCE - 655BCE.
