That's interesting -- so JP II was born and buried under solar eclipses.
Past speculation had it that Olive might be a reference to Jewish heritage and the Benedictine Order which also does something like have an olive branch as a symbol, had claimed this pope would come from their order.
Already he has claimed the name "Benedict" which someone said means "of the olive". But I'm wondering if there are stronger links? Is he of Jewish heritage? Or of the Benedictine Order?
