The teacher who worked out the new version, Andrew Wilson, from Bedford, says it's the longest text translated in 1,500 years.

It's hoped that by having such a popular book written in Greek it will encourage people to learn the language.

The book will come out later in the year, at the same time as an Irish Gaelic version, but the Scottish Gaelic one won't be ready for five years.

Mr Wilson has had some problems working out what some of the Greek versions of the words were.

Harry Potter becomes "warrior goblet" and Ron Weasley is now called "pomegranate tree".

Earlier this week Mr Wilson read his version of the Philosopher's Stone to some school children.
