Ugh, my post disappeared. Trying again:
The problem is that there is no documentation that a goddess Eostre/Eostra ever existed. She's entirely made up. In fact, there is no such thing as an Anglo-Saxon pantheon.
There is a Scandanavian goddess Ostara, but any attempts to link her to Easter have failed.
The overall theme is that some Christian holidays were purposefully placed at the same time as local indigenous holidays to make conversion more palatable. There were, however, uniquely Christian holidays. (Or, at least as unique as a religion that evolved from those before it could be.)
True terror lies in the futility of human existence.
Malcolm Reynolds is my co-pilot.
"The only freedom deserving the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental and spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest." - John Stuart Mill
