Ok, I have to stop you here and address just how badly this video destroyed so-called geodesy.  Geodesic science admits, readily, that they form their model after creating a model for them to measure their model from.  Seriously? That means it isn't a measurement of the real world, but a measurement from a model they created, after they assume it is a globe.  Yep, that's pretty down and dirty.  It's called begging the question. Even if you say they measure "the length of an arc corresponding to a geodetic latitude difference at two places along the meridian"...What? A meridian they created but never actually measured?  They admit they don't measure anything real but all of it is assumed before they measure.  Why?  Because they can't measure an arc that doesn't exist.  It's a scam.  Earth isn't a ball. All the formulas are based on presumption. Talk about cheating. Later, the flat earthers literally destroy every other fake narrative in relation to this crazy scheme with all sorts of great arguments. Sorry Cassini, this is truly embarrassing for anyone who takes stock in this chimera.

Ladislaus:
That reminds me of the circular logic between the geological column and fossil records.  They date fossils based on the geological column, and they date the geological column from the fossils in it.

Following on from my last post, the 'Catholic' aspect of the flatearthers, let me show everybody what must be eliminated as Catholic 'fiction.'

Our choice of reading for this purpose comes from the private revelations to Sister Mary of Jesus, known as Mary of Agreda (1602-1665), a nun known to have bilocated over 500 times to America without leaving her convent in Spain. The following are insights, dictated to her, she said, by the Virgin Mary herself in 1637, a mere four years after Galileo’s trial. Her three-volume work was entitled; ‘The Mystical City of God’ also known as ‘The Divine History and Life of the Virgin Mother of God.’ These revelations to Venerable Maria, whose body now lies miraculously incorrupt in a Franciscan Monastery in Spain, have withstood many years of investigation and misinterpretation, placed on the Index in 1681 and lifted 3 months later before receiving approbations from popes as a way to gain a deeper understanding of the Catholic faith in line with traditional Church teaching. Here is a passage most relevant to the shape of the Earth;

'God created the Earth co-jointly with the heavens in order to call into existence hell in its centre; for, at the instant of its creation, there were left in the interior of that globe, spacious and wide cavities, suitable for hell, purgatory and limbo. And in hell was created at the same time material fire and other requisites, which now serve for the punishment of the damned.--- Mary of Agreda: The Mystical City of God.’

Thank you very much cassini for this very enlightening and tradition affirming passage from the monumental and (contrary to some even to this day misconceptions) fully Church approved work by Venerable Mary of Agreda whose body still rests beautifully incorrupt.  The exact passage is found in Paragraph #82 of Chapter 7 of Book 1 of Volume 1 which can be examined at the following hyperlink: http://www.neemcog.com/index_files/ConceptionChVII_nee.pdf

Please be advised of the following official letter that was sent to Miss Mary Frances Lester, Editor of Tan Books on February 7, 1998 by Archbishop (later Cardinal) Tarciscio Bertone in his capacity as Secretary of the Sacred Congregation for the Doctrine of the Faith.  A copy of this letter can be found on p. XX of Volume 1 of The Mystical City of God published by TAN Books.  The exact verbatim text of this letter is seen below between the asterisks.

Dear Miss Lester:

    This Congregation writes in reply to your fax message of October 29, 1997, in which you asked if there are currently any restrictions on keeping or reading The Mystical City of God by Venerable Maria of Agreda.

    Please be assured that at the present time there is no condemnations or restrictions issued by ecclesiastical authorities with regard to this book.

    With kind regards and prayerful best wishes, I remain


                                                                        Sincerely yours in Christ
                                                                        [Signed Tarciscio Bertone]

We've covered this before in other threads, maybe you didn't see it. 

There was an official condemnation of the Mystical City of God by Mary of Agreda for these reasons

1. It violated the decree of Pope Urban VIII (March 13, 1625)
2. It narrated apocryphal stories.
3. It presented opinions of the Duns Scotus theological school as divine revelation.
4. Mary of Agreda pictured the earth in the form of an egg, i.e. that the earth has a spherical shape.
5. It exaggerated the cult of Our Lady to the extent of obscuring the great Mystery of the Incarnation.

152 Masters of the Sorbonne discussed the Mystical City on thirty-two sessions, July 2-14, 1696.  102 of the 152 Masters voted against the book. At all events, Blessed Innocent signed the condemnation on June 26, 1681.


Now, this shows a couple of things.  Number 1, how seriously dangerous the head of the Church and the bishops considered the spherical earth. They certainly did not agree.  But secondly, the pope doesn't seem aware that the snow globe world consistent with flat earth was probably what Agreda was describing. The way her description was worded suggested the earth itself was a sphere but maybe she wasn't trying to say that. In any event, they banned the book. As stated before, flat earthers see all of creation as a globe: with hell at the bottom, in the belly of the snow globe. Flat earth in the middle. And heaven makes up the top portion of the "globe".  This exact description is historically preserved in the traditions of Catholic culture as the "globus cruciger"*.  The Church is proven to be in defense of the flat earth against the pagan notion of spherical earth, even to the point of condemning Agreda's book.

From wiki, on the historic globus cruciger
*A possible non-literary but graphic indication that people in the Middle Ages believed that the Earth (or perhaps the world) was a sphere is the use of the orb (globus cruciger) in the regalia of many kingdoms and of the Holy Roman Empire. It is attested from the time of the Christian late-Roman emperor Theodosius II (423) throughout the Middle Ages; the Reichsapfel was used in 1191 at the coronation of emperor Henry VI. However the word 'orbis' means 'circle' and there is no record of a globe as a representation of the Earth since ancient times in the west till that of Martin Behaim in 1492. Additionally it could well be a representation of the entire 'world' or cosmos.

and there is no record of a globe as a representation of the Earth since ancient times in the west till that of Martin Behaim in 1492.

O.K., Tradman, here is another Saint you can promote as a fraud because she too described the Earth as a globe and not flat.

Saint Hildegard of Bingen (1096 to 1180) a saint who was made a Doctor of the Church in 2012. Confined to her bed as a child, Hildegard received visions that continued throughout her life. When she was seven her parents sent her off to a religious life in what became a small Benedictine convent within which she eventually became its head.

‘Hildegard’s life changed radically when she was forty-two. She had the most powerful vision yet, of inspiration, of understanding, an infusion of knowledge about the meaning of Scripture and the whole content of the faith. She also received the command to write down what she learned, which she did for the next thirty years. Her first and greatest work, Scivias, tells in three books of God and all of his creation, of redemption, the Church, and the devil, and finally about the whole history of salvation. First the abbot read portions of it, then the archbishop of Mainz, then St. Bernard of Clairvaux and then Pope Eugenius (1145-1153), who read her writings out loud himself to a synod held in the German city of Trier. The word was out. A true prophetess lived on the Rhine. Hildegard’s solitude, as limited as it had been, was over. --- Crisis Magazine, Sept. 9th, 2012.

‘In Hildegard’s universe, the Earth was the centre, and spherical, around which were arranged concentric shells or zones. The inner zones are spherical, the outer oval or egg-shaped, and the outermost so formed as to suggest the acuмinated sphere that symbolises the fifth element, quintessence of the other four. This point that tapers into outer space is in the East, which is the top of the diagram. One of her drawings, says Singer, shows that she believed the antipodeans surface of the Earth to be uninhabitable, “since it is either beneath the ocean, or in the mouth of the Dragon.” In the interior of the Earth, she believed, are two vast spaces shaped like truncated cones, where punishment was endured, and from whence great evil came forth.’

I found this description of the Earth very interesting. As I said before, it was Isaac Newton who proposed a bulging Earth to go along with his solar-system, a bulge depicted in astronomy books looking like a rugby ball, the shape your man on the video rightly laughed at. Domenico Cassini knew that was an invention and went out and measured the Earth as egg shaped. The truth will out says the Bible.
Finally, how many saints have been inspired to describe a flat Earth in their 'sacred texts?'
