In a short week in Dublin, I passed by almost every day. Unfortunately, I never went to the school library during the opening time. Every day it's dark when the bus comes back and the library closes. It was not easy to have a weekend afternoon opening time to go, but did not advance booking, that day happened to be a mass, the school was full of people, tickets sold out, and did not see. Trinity College is one of the oldest colleges in Europe, just like Oxford and Cambridge. Her library retains the Book of Kells, the most important classic of Celtic and even Christian civilization. It is said that this is a magnificent manuscript of the Gospel of the Bible, each beginning with an illustration, a total of 2,000. Because most people in ancient times were illiterate, churches and scriptures used a lot of pictures to spread the doctrine. The Kyle Sutra is Ireland's most precious national treasure.
