Jesus’ Failed Prophecy About His Return

[Belacqua]

All of the sources I have ever seen say Cyril opposed her due to political intrigues.

"opposed her"? I say that's some opposition. You really should look out of Christian sources more

I'm not using "Christian sources." I'm using modern history texts. (I'm not a Christian. I'm a scholar. I want people to stop repeating historical falsehoods.)

As for the video, Sagan repeats a historical falsehood. He claims that the "seeds" of Alexandria didn't take root -- that they "slumbered" for a thousand years until Columbus and Copernicus revived them. But historians have long recognized that the so-called "middle ages" were an active time intellectually. Not as active as other times, but not the "dark ages" that they have sometimes been portrayed as. (And even when historians used the term "Dark Ages" it didn't refer to a time period of 1000 years.) Nor did Columbus "revive" anything. Everybody had known that the earth is round for a long time. And Copernicus didn't "revive" the knowledge of Alexandria, because Hypatia and the other Alexandrians believed in a geocentric universe. 

Here is the Wikipedia article:

https://en.wikipedia.org/wiki/Hypatia

We can start there. If something seems incorrect there, please provide me with another source that says something different. 

Here is the entry on the Library of Alexandria:

https://en.wikipedia.org/wiki/Library_of_Alexandria

Note that in the section under "Decline," it says that while Julius Caesar accidentally burned some part of it, the rest gradually declined and lost its importance. The great library was gone before Hypatia lived. There was a successor, but it's not known how big it was. When the Christians got angry at the Neoplatonists (whose ideas you would also hate) and destroyed the temple at the site of the ancient library, scholars find no indication that there were any books left.

Again, this is just Wikipedia, but everything there is consistent with other books I have read. If you can find a source that contradicts the Wikipedia article I will happily read it. 

Please, this time use genuine sources.
