Never seen Agora but I can tell you its complete rubbish. This is what happens when you allow secularists of the 'enlightenment era' to write history books. They have to slander the previous era in order to make their modern day history look and smell like flowers.
The remaining remnants of the Alexandrian Library was burned down by muslims in 642 AD, by the order of Caliph Omar. The Great Library was composed of a series of buildings not just one.
All primary sources agree that the bulk of the library was burned down by Julius Caesar in 48 BC during the siege of Alexandria when Carsar and his forces were battling Ptolemy XIII.
The killing of Hypatia did not involve Cyril of Alexandria. There are other threads on this forum. Christian parents would send their children to be educated by Hypatia. Her most famous student was the bishop Synesius of Cyrene, some of his letters and correspondence to Hypatia still exist and can be found online
Hypatia was killed by a fanatic which the primary source (which is Socrates Scolasticus) says was a reader named Peter. The events leading to her death was during an outbreak of violence between the jewish, pagan, and christian communities which at times turned to mob riots, . Hypatia was caught up in one of these mob riots, her murder brought condemnation upon the entire alexandrian church, The condemnation also came from christian communities as Scholasticus writes.
This affair brought not the least opprobrium, not only upon Cyril, but also upon the whole Alexandrian church. And surely nothing can be farther from the spirit of Christianity than the allowance of massacres, fights, and transactions of that sort. This happened in the month of March during Lent, in the fourth year of Cyril's episcopate, under the tenth consulate of Honorius, and the sixth of Theodosius.
This idiotic myth of Cyril killing her comes from a 10th century source attributed to a pagan philosopher known as Damascius who lived in 500 AD. According to this fiction the rulers of Alexandria all envied her, just like the leadership did in Athens when she first resided there. Cyril got jealous of her one day after passing by her house as there was a crowd of admirers in front of her home. Interestingly Cyril is refered to as being the "bishop of the opposition sect'. It is either a reference to the Arian heresy or mistakenly references the nestorian or monophysite heresies.
Unfortunately western scholarship considers this bizarre story found in the 10th century Suda as a primary source
