They offer The Book of Margery Kempe, many of Gower's works and John Lydgate, The Pearl, Robin Hood and Other Outlaw Tales, Charlemagne, Canterbury Tales and so many other texts all in Middle English but including a glossary. I recommend it highly.
The other link is to a gardening site. The Metropolitan Museum of Art purchased some architectural elements of a Cistercian cloister from Bonnefort, France among others and reassembled them in New York. Sounds like it is worth a little visit. Here is the visitors page: http://www.metmuseum.org/cloisters/ But the link that I really wanted to post is for the medieval garden at the Cloisters. It is rare to find a blog on medieval gardens and it has photos as well. Here is a link: http://blog.metmuseum.org/cloistersgardens/
I think you should bookmark it.
