Many things of human origin can be described as 'timeless' in that
regardless of what era they are placed they evoke the same feeling of
satisfaction as they originally did.

Nothing in human origin can be describes as timeless.



The example of Copernicus being that rather than looping/wandering
motions intrinsic to individual planets as they move around a stationary
Earth, the correct resolution is a faster moving Earth overtaking slower
moving planets in a Sun centered system -

The example of Copernicus is that following on from the astronomical work
of Tycho Brahe heliocentric system of Aristarchus of Samos (he deleted all
mention of him from his published works but left them in the notes for
scholars to discover) the heliocentric system could be put on a better
theoretical basis.

The narrative of human involvement in timekeeping is also spectacular
even if the story is extended across many thousands of years where
timekeeping comes into close proximity to the daily and orbital cycles of
the Earth, in fact, timekeeping is also a timeless positive of human
history. It too has a founding image attached, in this case the first
annual appearance of a star to the right of the Sun or a dawn appearance
as observers would register it -

It's easy to summarise human involvement in timekeeping - we got better and
better at it and now we can measure time with such accuracy that we know
how unreliable the movements of the Earth are as the basis of time
measurement.

It is the sight of this star which determines the proportions of
rotations to orbital circuits and specifically the close proximity of
1461 rotations to 4 orbital circuits which reduces, by logic, to 365 1/4
rotations to one circuit.

No it was a clue for ancient astronomers who would have done anything for
the accurate time measurements we now have available.

The great events of Holy Week are designed around astronomical events but
denominational Christianity has unfortunately lost the significance and
the joy of its astronomical heritage and will always lacking something on that account.

The celebrations of the superstitious at this time or year depend in the
lunar calendar which is so imprecise a measurement of the solar year that
it needs long calculations to work out the date of Easter. (And these
usually in dispute between Orthodox and Catholic witch doctors.
