Do some research and find out for yourself if the man credited with bringing Christianity to Ireland also rid the island of all serpents. In order to get the extra credit for this one, you MUST cite the source you got it from. If you got it from a book, mention the name and author of the book. If you got it from a website, you have to COPY and PASTE the web address in your comment. To be eligible for extra credit, this must be posted by Wednesday, February 2 to this blog entry.
Oh, and by the way, once someone has used a source, NO ONE else can use it. Good luck!
