Domenico Cassini was what I call God's astronomer. A geocentrist in his time on Earth, he measured the shape of the Earth's globe and found it was not as Isaac Newton claimed for his heliocentrism. He also falsified Kepler's ellipse upon which modern cosmology is based. His Cassinian oval, the orbits of planets and the sun, was later linked with electromagnetism and with the mathematical relationship called phi, now known to be frequently evident or expressed in many natural things. For example, by varying the angle between the adjacent radii (their relative lengths conforming to the Phi proportion) a number of natural spirals are produced such as found in snails, shellfish, leaf-shapes, spiral galaxies etc. Because of his falsifications of Newton and Kepler, his contribution to the world's science has been hidden and forgotten once heliocentrism took over in Church and State.
Here then is the history of a world map readers will be familiar with:

"In 1669, Jean Baptiste Colbert recruited Cassini to come to Paris and join the French Royal Academy. Cassini became a naturalized citizen in 1673. While Cassini's main investigations were astronomical in nature, in 1679, King Louis XIV commissioned Cassini to construct a scientific map of France based upon astronomical observations, one of Cassini's other masterworks. In the same year, Cassini began laying out a World Map on a North Polar Projection based upon astronomical observations gathered from around the globe. A 24 foot diameter hemispheric projection was drawn in ink on the third floor of the Observatory of the Royal Academy outside of Paris.

The map shows 43 places, from Quebec to Santiago, from Goa to Beijing, each marked with a star, with latitudes accurately measured using a method that relied upon observation of the moons of Jupiter. By 1690, the ink drawing on the floor of the Observatory was fading, so at some time during the 1680s, it was transferred to paper and ultimately printed in a single sheet format for the first time by J.B. Nolin in 1696, placing a star in each or the 43 locations where astronomical observations were taken.

A number of the most important mapmakers would copy this work, in the 18th Century." As a projection even if it were not that important you could reasonably expect for this great North Polar Projection of Cassini's to be of some interest to geocentrists!

Its relevancy as a projection is in no way diminished by it being incorporated into the logos of international bodies such as these

For anyone sensing that there is something vaguely familiar about this projection, could it be an example of one of those secrets deemed to be 'hidden in plainsight' such as in the ubiquitous flag/emblem/logo of the United Nations

Very interesting. Thank you. I need to learn more about Cassini.

The map also appears to be consistent with a flat earth.

‘Experimental evidence supporting this idea [that the Earth is shaped like an orange] came in 1672 as a result of a French expedition to Guiana. The explorer [Jean Richer (1630-96)] found that a pendulum clock that kept good time in Paris lost 2½ minutes a day at Cayenne near the Equator. At that time no one knew how to interpret the observation; but Newton’s theory that gravity must be larger at the poles (because of its closer proximity to the Earth’s centre) than the Equator was a logical explanation. It is possible to determine whether or not the Earth is an oblate spheroid by measuring the length of an arc corresponding to a geodetic latitude differences at two places along the meridian (the ellipse passing through the Poles) at different latitudes, which means at different distances from the Equator.’[1]

[1] Encyclopaedia Britannica, chapter: Earth, p.535.

King Louis XIV of France approved Cassini’s last great expedition. With the aid of his son Jacques Cassini and others, he measured the arc of meridian from Paris north to Dunkirk and south to the boundary of Spain, and, in addition, he conducted various associated geodesic and astronomical operations that were reported to the Academy. Cassini knew that it would be virtually impossible to measure every kilometre of meridian from Pole to Pole at the time. At best, a partial measurement would confirm a probable shape of the Earth. Consequently they decided to measure where it was most convenient, restricting their efforts to Europe in the northern hemisphere.

The results showed the length of a meridian degree north of Paris was 111,017 meters or 265 metres shorter than one south of Paris (111,282 meters). This suggested that if this trend occurred in the southern hemisphere, the Earth has to be a prolate spheroid, not flattened at the poles as Newton proposed, [or flat] but the opposite, slightly pointed, with the equatorial axis shorter than the polar axis, that is, kind of egg-shaped. In 1720, Cassini published his findings.

How does an egg-shaped earth fit with gravity?

That would explain why North America looks completely wrong (i.e. not even close).

It falsifies Isaac Newton's assertion that the Earth bulges like an orange and consequently it spins like a gyroscope creating the seasons and causing precession. If it is egg shaped then it cannot spin like a gyroscope.

Domenico Cassini (1625-1712), using the means given to him by King Louis XIV (1638-1715) sought the history of astronomy up to his time through research of the world’s oldest and rarest books on the subject he acquired from around the Earth. I got a copy of this book in French and had it translated into English. Of special interest are the following pages:

‘There is no room for doubt that Astronomy was invented at the beginning of the World. As there is nothing more noteworthy than the regularity of movement among these great luminous bodies that turn unceasingly around the Earth, it is natural to think that one of the first interests of men was to consider their course and observe their periods. But mere curiosity alone was not solely responsible for leading men to set themselves astronomical speculations, for it can be maintained that necessity as well obliged them. For should one not observe the seasons that vary by the movement of the Sun, it would be impossible to make a success of agriculture; were one to fail to note the suitable times for travel, one could establish no Business; should one not have determined once for all the length of the month and the year, there could be neither order established between civil affairs, nor could days be marked out for religious purposes: hence as agricultural farming, commerce, politics and even religion cannot do without astronomy, it is obvious that men must have been obliged to study this science right from the World’s beginning.

Both sacred and secular history confirms this truth. What the Holy Scriptures say about the years that the ancient Patriarchs lived up to is proof positive that the first men studied the movements of the stars. For had they not taken account of the exact number of days that last in the varying phases of the Moon which serve to conceal the months; and of the number of months during which the Sun little by little approaches the Zenith and afterwards distances itself from it, making the changing by increase and diminution of the days, which allow one to establish the length of the year, they could not have noted the number of years each Patriarch had lived, nor the times of their birth and death, as precisely as Moses records it in Genesis.
And there certainly was need in this first age of the world to observe the stars with a great deal of care, for by the circuмstances of the history of the great flooding which are also reported in Genesis, one can see that the year from the time of the Deluge was regulated following the movements of the Sun and Moon: which supposes an infinite number of observations. It is yet to be understood how all the application imaginable by the first men studying the sky could have gained them so much knowledge of the movements of the stars, unless their lives were longer than ours. By the living of such long lives gained for them great advances in astronomy. Josephus was of the opinion that so necessary was this science that one of the reasons why God granted the first men such a long lasting life was to facilitate for them the knowledge of the movements of the stars.'

But there was yet a higher purpose to astronomy:

‘To what we have said on the usefulness of astronomy, one can add the advantages that have been drawn and continue to be drawn every day for the propagation of the Faith, because it is by the use and protection afforded by this science that those dedicated to preaching the Gospel to the Infidel, penetrate the furthest countries and live there not only in safety but even with full freedom to preach the truths of the faith, that they draw the admiration of peoples, and they work their way into familiarity with the powers that be, and they even win the favour of Sovereigns. Thus this science has opened up to missionaries the vast Empire of China, whose entry was forbidden by the laws of the land and for reasons of State to all foreigners, and it was used to obtain permission to build churches there and publicly to practice the true faith. This is why King Louis XIV wanted the missionaries who go to preach the Gospel to China, in the Kingdom of Siam, and in the other states of the East Indies, to be instructed in the ways the Academy makes observations, and that they take from it very ample memories of what they have to do and remember in their travels. The observations that these missionaries have already made in conjunction with the Academy and which they have sent back to it, compared with those made at the same time at the observatory, have already communicated great lights; and it is not to be doubted that progress will continue to be made in these far-off countries, greatly to contribute to the progress of astronomy; and if the persons who work at this science in foreign lands set up contact with the Academy and send it their observations, as the Academy offers likewise to share with them its own; there is reason to hope that shortly, not only astronomy, but also geography and the art of navigation will be raised to their highest perfection.’[1]
