Well just take what he says with careful comparison study.

I will indeed, but thank you for your input on Dean, very much appreciated.

 

[prodromos]

I agree -Thank you d Taylor

No you don't. You said it is proven that the horizon always rises to eye level.

 

[Apple Sky]

No you don't. You said it is proven that the horizon always rises to eye level.

I agreed with what @d taylor said. which was 'The way it should be understood is that on a flat plain, the horizon at the edges will not fall or bend away'.

He also said in that same post you said you agreed with:

The horizon will not always remain at eye level. The higher a person goes up the further they will see, so actually the line of sight. If one could see that far, would extend beyond the horizon, but a persons vision is limited on a plain.

which completely contradicted your ealier claim that it is proven that the horizon always rises to eye level. It is also complete nonsense. The law of perspective is that all parallel lines converge to a vanishing point, which on a flat earth would be on the horizon.

His comment about bending downwards of the edges of the horizon is completely irrelevant to what we were discussing. You can only witness this curvature of the horizon at really high altitudes. You can only see it at lower altitudes if you take a photo and then compress the image horizontally to make the curvature stand out. The horizon dropping below eye level is the effect the earth's curvature has when looking straight, in one direction.

Once again, you claimed it is proven, yet you haven't said how they determined eye level.

He also said this & this is the part I agreed with & I know I should have said - My bad.

I'm still waiting for your proof that the horizon always rises to eye level. On a flat earth that would absolutely be the case, so it should be easy for you to show if the earth is actually flat.

And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years. Genesis 1:14

These and the stars represent one huge universal clock, they represent time. The sun representing the big hand and the moon representing the small hand & the stars representing the minutes.

1. The sun = The days
2. The moon = The months
3. The stars = The seasons

These two great lights & the stars circuit the heavens.

It rises at one end of the heavens and runs it's circuit to the other. Psalms 19:6

God who created the universe according to the laws of physics and set it in motion like a well-made clock.

All these he set in the firmament.

And God set them in the firmament of the heaven to give light upon the earth, Genesis 1:17

Then you added this, which doesn't match any observations. According to the above, the sun should always be in the line of sight from anywhere on the earth, but simply get dimmer as it gets further away. Sunsets would never occur. Of course it simply cannot explain the 24hr sun in Antarctica

This is complete bunk. Please explain why you believe they could not work on a globe.

Sun dials don't work on a globe because of the inaccuracies from the Earth's supposed elliptical orbit and axial tilt, making them different from clock time.

Sundial - Wikipedia

en.wikipedia.org

Sundials may indicate the local solar time only. To obtain the national clock time, three corrections are required:

1. The orbit of the Earth is not perfectly circular and its rotational axis is not perpendicular to its orbit. The sundial's indicated solar time thus varies from clock time by small amounts that change throughout the year. This correction—which may be as great as 16 minutes, 33 seconds—is described by the equation of time. A sophisticated sundial, with a curved style or hour lines, may incorporate this correction. The more usual simpler sundials sometimes have a small plaque that gives the offsets at various times of the year.
2. The solar time must be corrected for the longitude of the sundial relative to the longitude of the official time zone. For example, an uncorrected sundial located west of Greenwich, England but within the same time-zone, shows an earlier time than the official time. It may show "11:45" at official noon, and will show "noon" after the official noon. This correction can easily be made by rotating the hour-lines by a constant angle equal to the difference in longitudes, which makes this a commonly possible design option.
3. To adjust for daylight saving time, if applicable, the solar time must additionally be shifted for the official difference (usually one hour). This is also a correction that can be done on the dial, i.e. by numbering the hour-lines with two sets of numbers, or even by swapping the numbering in some designs. More often this is simply ignored, or mentioned on the plaque with the other corrections, if there is one.

Of course this is all moot because sundials do have to have adjustments made in order to match clock time, thus you have just debunked yourself, proving the earth is not flat.

While clocks emerged, sundials continued to be used and were still in use for setting clocks as late as the 19th century.
Nothing about any adjustment too sundials.

You can see for yourself that the sun is in a different position at noon in the middle of Winter compared to where it is in Summer at noon.
Its an easy experiment. Hammer a stake into the ground where you get both Winter and Summer sun. On June 21st, mark the line of the shadow at noon, then do the same on December 21st. The shadows won't just be different lengths, they will be slightly different angles too. You can check a few days in either direction, just in case you don't have sun on those days. You do live in Wales after all.

Unfortunately, you just accept whatever you hear from flat earthers without testing whether the claims are true for yourself, and this one definitely fails the test.

Sundials record the movement of the sun, as shown in The Bible.

And the word of the Lord came to Isaiah, saying, “Go and tell Hezekiah, ‘Thus says the Lord, the God of David your father: “I have heard your prayer, I have seen your tears; surely I will add to your days fifteen years. I will deliver you and this city from the hand of the king of Assyria, and I will defend this city.” ’ And this is the sign to you from the Lord, that the Lord will do this thing which He has spoken: Behold, I will bring the shadow on the sundial, which has gone down with the sun on the sundial of Ahaz, ten degrees backward.” So the sun returned ten degrees on the dial by which it had gone down.
-----------------------------
And Hezekiah said to Isaiah, “What is the sign that the Lord will heal me, and that I shall go up to the house of the Lord the third day?”
Then Isaiah said, “This is the sign to you from the Lord, that the Lord will do the thing which He has spoken: shall the shadow go forward ten degrees or go backward ten degrees?”
And Hezekiah answered, “It is an easy thing for the shadow to go down ten degrees; no, but let the shadow go backward ten degrees.”
So Isaiah the prophet cried out to the Lord, and He brought the shadow ten degrees backward, by which it had gone down on the sundial of Ahaz.

Amen!
God is master of His creation.

No I don't, you said that they had to make adjustments to these sundials, why after so many thousands of years of using them would they feel the need to adjust them ?

Could it be the fairy tale globe kicking in again ?

From the same wikipedia article you quoted from:

Since the Greek dials were nodus-based with straight hour-lines, they indicated unequal hours that varied with the seasons, since every day was divided into twelve equal segments; hours were shorter in winter and longer in summer. Sundials with gnomons oriented towards the celestial pole are able to exploit the fact that the markings for the equinoctial hours are a family of straight-line segments, thereby allowing for the measure of equal hours.​

If they didn't adjust, it meant that the hours during Winter could be as short as 40 minutes and the hours during Summer could be as long as 80 minutes for the same shadow movement.

I agree. It also seems to me, as a non-scientist, that a flat earth does not explain why it is summer in the UK at the same time as it is winter in Australia, and vice versa.

What makes you think that sundials have been adjusted ?
