When was the word "boredom" first used in print?

I enjoy etymology: this was enlightening. I am reliably informed by my friend that "Albion" is another name for King Arthur's sword, Excalibur and an ancient name of Great Britain. Also, according to the BBC series "Sister Boniface Mysteries" the fictional newspaper in the equally fictional town of Great Slaughter, UK is "The Albion". What fun! :)
