Trinity College is the oldest university in Ireland and among the older ones in Europe. One of the virtues of being founded so early (1592) is that you get to claim a prime spot in the heart of the city. And Trinity College is right in the middle of things, its large green spaces protected from the bustle of central Dublin by buildings dating as far back as 1712.
That's all well and good, but the reason most casual visitors stop by this place is the Book of Kells, an elaborately illustrated Latin translation of the four gospels of the New Testament. Unfortunately, you're not allowed to take pictures of it. And since they only display two pages at a time -- one of illustrations, and another of text -- you're not going to be able to see the whole thing. They do change the pages that are on display regularly.
Before you reach the book, you walk through an exhibit on its history. This was pretty interesting. It described the processes that would have been involved back then in making a book like this, such as the kind of materials used and how these were acquired. One of the inks, for instance, came from lapis lazuli, whose only known source at the time was a mine in Afghanistan. It also talks about who wrote the book and where it has been over the years.
But why look at just one book when you can see thousands. After you emerge from the Book of Kells viewing area, you come to the old library of Trinity College. Stacks and stacks of old books, piled to the ceiling. It made me wonder, how did anybody ever find anything before Google?
Also on display at the library is the oldest harp in Ireland, which is apparently the model for the Guinness logo. You can't play it, though. There are model harps in the gift shop that you can play. But be careful, they are easily and noisily knocked over.
