After our dendrochronological re-investigation of European major oak- and pine-chronologies, we suspect that the part anchored archaeologically in Roman time is dated 218 years too old conventionally (see under tab "Dendro audit").
To validate this puzzling result, we have been looking at historical astronomical observations and tried to verify them towards the NASA catalog of eclipses. We have described this effort under tab "Ancient history", where we conclude that if we are right, then the error in our time count is exactly 232 years (though the dendrochronological error is "only" 218 years).
Very recently we had a discussion about the Julian star, which is historically described in multiple sources as a comet that occurred after the assassination of Julius Caesar in RomBC 44. As a commemoration of this event, the star can be seen on several Roman contemporary coins. However, it has been hard to find a celestial body which exactly matches the observations, therefore certain scientists regard Caesar's star as fiction.
This is not miraculous, because if we are right about this 232 years calendar error, then everybody has been looking at the wrong place on the astronomical time line. Looking instead 232 years later than assumed conventionally points at a comet exactly matching the sources, which indicates that we actually might be right.
