Easter

"There's a similar myth on Earth — Merlin could see the future because he actually aged backwards in time. It's not meant to be taken literally, but we have seen that a lot of legends in folklore have a strong basis in fact: Avalon, Atlantis..." "The Easter Bunny."

- Daniel Jackson och Teal'c

Easter is a Earth made event is celebrated around the world, between 22 March and 25 April each Earth-year.

In 2006 in SG-1 was Camelot in the search for Merlins anti-Ori weapon met Anthonius and asked him if Merlin. Doctor Daniel Jackson told me that there is a reference about Merlin's prophetic abilities that he could see the future.
