The hills of western Thebes block the view of the summer solstice but not the winter solstice. This has been known since just after Lockyer postulated the alignment with the summer solstice. Do you think they aligned the temple to a solstice that couldn't be seen (summer) or one that could be seen (winter)

One that could be seen...at the time..
So, if this temple was built in the Middle kingdom, if the
dates are anywhere near correct here, that would be post flood, and split. The dates are all that we need here. The difference between 2040, and 2345 is about 300 years. I don't see how that changes much. The data that Dodwell provides shows a clear pattern, and a few hundred years either way doesn't really affect anything much.
"The construction of Karnak Temple began in the Middle Kingdom...."
Middle Kingdom, 2040-1640 B.C.

The Dodwell data agrees with the Newcombe curve within known times of a few thousand years. The divergence comes as we progress backward in time.

Figure 1 shows, on a small scale, how the discrepancies appear when they are set out on a graph, and the Scale is magnified in Figure 2. The observations which they represent belong to widely separated times and places, the latter including Ancient China, India, Egypt, Greece, and various parts of Asia Minor and Europe.
They agree ... consistently, throughout all times and places...."

For those interested, here is a quote from Lockyer:
'Taking the orientation as 26°, and taking hills and refraction into consideration, we find that the true horizon sunset amplitude would be 27° 30'.This amplitude gives us for Thebes, a declination of 24° 18'. This was the obliquity of the eclipse in the year 3,700 B.C., and is therefore the date of the foundation of the shrine to Amen-Ra at Karnak..' (1).
Right, so this guy has the dates wrong. Also, he has no way of knowing what anything was 3700 BC! Whatever he used to get there is false. What he means is 'This would have been the obliquity of the eclipse in the year 3700 IF present backwards extrapolation methods worked'
This date is disputed by Egyptologists as it is unclear which part of the setting sun was used as the 'setting marker' (i.e. edges, top, centre, first glimpse, last glimpse etc), an argument often used against Lockyer, who was accused of using different 'setting markers' at different sites. Recent excavations have pushed the history of Karnak back to around 3200 BC (4), when there was a small settlement on the bank of the Nile where Karnak now stands.
Balderdash. The dates can't be supported. Basis?
So dad, do you accept the date of 3,200 B.C. for the history of Karnac as it says on the site you linked? Or as typical do you only accept out of context bits that support your position even when the site you link disagrees with them and you?
...
The date 3200BC would be something like 6 or 7 hundred years before the flood. Why would I accept such an unsupportable dream date?? There is no basis for the date.
Either Dodwell was right in the general pattern or not...

The conclusion thus reached is that the deviation from the theoretical curve of obliquity is due either to errors of observation, or to the existence of some abnormality of an unexpected kind.
The following pages show that
errors of observation are quite inadequate to explain the increasingly large deviation when the curve is traced back to ancient times.
Also, since the curve itself is so
plainly a logarithmic one, we are limited to the interpretation which that implies. That is to say, at the zero end, where the curve becomes vertical there is irregularity, corresponding to a sudden and major disturbance of the earths axis; and at the 90º end, where the curve becomes horizontal, there is insensibility, or restoration to equilibrium.
In other words, it is a
curve of recovery after a large disturbance of the earths axis of rotation, the disturbance having occurred in the year 2345 B.C.,
and the restoration to equilibrium having been brought to completion in the year 1850 A.D.

Speculation on summer sun positions, or winter ones aside, there is no way that you can make the dates sufficiently off course enough to really matter to the basic claim of Dodwell.
