Going on memory, there is the one about women turning into men or something like that, its been awhile since I read the GOT.
If so, that would be the only biblical miracle that modern society has been able to achieve in the 20th/21st century!
OK, back on the serious topic: I have long wondered about the suppression of non-canonical material as sort of a point of religious honor...For one thing there are many points in the accepted canon that seem out of place or contradictory.
Looks to me like (historically at least) all of the archealogically authentic writings should at least be considered in the eyes of history - but of course I am viewing it without any religious prejudice.
