Domenico Cassini's map of the Earth
« on: October 04, 2019, 11:26:44 AM »
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:
On the "Rare Maps"  website

"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

https://en.wikipedia.org/wiki/World_Meteorological_Organization
https://en.wikipedia.org/wiki/International_Maritime_Organization

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

Here is a copy of the 1696 J.B. Nolin map taken from the Library of Congress's website from where it can be accessed, roatated and zoomed interactively.

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).
