I had in mind the English speaking tradition.
"Easter" is derived from "Aester" the Anglo- Saxon goddess of spring and fertility.
Her totem animal was the hare and one of her symbols was the egg. Pretty clear.
Even more interesting is the true identity of Santa Claus.
His characteristics:
Is a large, old man with a grizzled beard
Lives in the far, snowy North
Flies by means of magical animals
Has magical means of spying of the activities of people
His helpers are elves
Visits people secretly
Can cloak himself with invisibility
Sometimes bestows gifts if the person has been good and requests them
So who is Santa Claus? He is Wotan-Woden-Odin. Santa's and Wotan's characteristics match very closely
Of course Wotan was a rather darker figure than Santa, but he has been sanitized for the kiddies.
1) Christmas and Easter are not "pagan" holidays in the sense that Halloween is, since they celebrate Christian history in a manner not nearly as associated with paganism as Halloween (Christmas, whatever else it is, celebrates Christ's birth, and Easter his resurrection--it doesn't matter that they are near pagan holidays on the calendar).
2) The Christmas tree is purportedly a tradition started by Martin Luther, according to some.
3) Santa Claus is derived from the Dutch spelling of Saint Nicholas, a Christian bishop in Turkey from a long, long time ago (over a millenium) who was well-known for some incidents involving anonymously giving out gifts of money to needy families. The special powers, etc., were not introduced until the late 19th century in an effort to commercialize the holiday more.
4) Valentine's Day is also a subject of debate, as some say that it is the day held in honor to St. Valentine, an early Christian.
5) I do not celebrate Halloween, although I do celebrate Christmas and Easter (I find Easter a lot more meaningful, however). I do not "throw out the baby with the bathwater," as the saying goes, in thinking that any holiday remotely associated with paganism either by date or name (in Easter's case) is evil. I simply find little in Halloween that resembles "All Hallows' Eve" more than Samhain.
