There are several things about our culture's two favorite holidays Christmas and Easter that are very ironic. One is that both of them are ancient pagan celebrations, with no necessary connection to Christianity or any other modern religion whatever. Whether a Yule log is burned, or Christmas bonfires are lit, or just candles, there is always light. This is also clear in the festival the Jews created for the same time, Chanuka, which is also called the festival of lights. And the symbols for the vernal equinox, or Easter, are also completely pagan, from nature religions and ancient agricultural societies.
Easter is about new life.
The two prime symbols of Easter are that timeless symbol of fecundity, the rabbit, and those numberless symbols of fertility, eggs this isn't subtle. And Easter lilies probably began as Eostre s flower. It was said they were lily white because they grew from Eostre s milk. Later, the Romans said the lilies were Juno s and were white because they grew from her milk. And still later, the Christians identified Easter lilies with the Virgin Mary, and said they were white because they grew from her milk.
