    Is that the principle that the cream separators are base on? Now I know why. I suppose the same doing fenceing, the deeper the more hard the digging. Maybe also when burying bloated cows the heaviest part the stomach, is flat up against the ground and therefore hardest to budge.

    Zionism is racism as defined by the UN, Israel by every dirty means available steals land and water, kill Palestinian freedom fighters and civilians, and operates an apartheid system to drive more Palestinians off their land

    So you have no examples from Medieval times. Good - that establishes my claim (at least provisionally). And I was comparing Medieval understanding with modern understanding - I never made any claims about the Greek or Renaissance understanding of reasons for the Earth's shape.

    I've never made the claim that everyone in the Dark Ages thought the world was flat, so that's just a furphy. And the term "Dark Ages" is a well recognised term for a specific period - it's not (in itself) a claim about anything! The fact that you don't like it doesn't mean that I can't use it

    Are you suggesting that Medieval scholars thought that the Earth was spherical due to attractive forces between masses? If so, provide evidence; otherwise it's irrelevant.

    That list is extensive, and even if correct, many are before or outside Christianity. Note that the destruction of the Great Library of Alexandria, which atheopaths have loved to blame on a Christian mob, was actually destroyed by Julius Caesar, but this atheopathic myth is another that won't die.

    Medieval proofs of the sphericity of the earth

    That indeed was one of the reasons. The different stars visible from different latitudes, and stars appearing at different angles, showed that it was round in the north-south direction; and the different times of night that phenomena such as lunar eclipses were seen in different longitudes showed it was round east-west as well. This was also well known to medieval students, because they used as an astronomy textbook The Sphere, by Johannes de Sacrobosco (1230):

    THE EARTH A SPHERE. -- That the earth, too, is round is shown thus. The signs and stars do not rise and set the same for all men everywhere but rise and set sooner for those in the east than for those in the west; and of this there is no other cause than the bulge of the earth. Moreover, celestial phenomena evidence that they rise sooner for Orientals than for westerners. For one and the same eclipse of the moon which appears to us in the first hour of the night appears to Orientals about the third hour of the night, which proves that they had night and sunset before we did, of which setting the bulge of the earth is the cause.

    FURTHER PROOFS OF THIS. -- That the earth also has a bulge from north to south and vice versa is shown thus: To those living toward the north, certain stars are always visible, namely, those near the North Pole, while others which are near the South Pole are always concealed from them. If, then, anyone should proceed from the north southward, he might go so far that the stars which formerly were always visible to him now would tend toward their setting. And the farther south he went, the more they would be moved toward their setting. Again, that same man now could see stars which formerly had always been hidden from him. And the reverse would happen to anyone going from the south northward. The cause of this is simply the bulge of the earth. Again, if the earth were flat from east to west, the stars would rise as soon for westerners as for Orientals. which is false. Also, if the earth were flat from north to south and vice versa, the stars which were always visible to anyone would continue to be so wherever he went, which is false. But it seems flat to human sight because it is so extensive.

    SURFACE OF THE SEA SPHERICAL. -- That the water has a bulge and is approximately round is shown thus: Let a signal be set up on the seacoast and a ship leave port and sail away so far that the eye of a person standing at the foot of the mast can no longer discern the signal. Yet if the ship is stopped, the eye of the same person, if he has climbed to the top of the mast, will see the signal clearly. Yet the eye of a person at the bottom of the mast ought to see the signal better than he who is at the top, as is shown by drawing straight lines from both to the signal. And there is no other explanation of this thing than the bulge of the water. For all other impediments are excluded, such as clouds and rising vapors.
