What is the book of calles?

Well, honey, I think you mean the "Book of Kells," not "calles." It's an illuminated manuscript Gospel book in Latin, containing the four Gospels of the New Testament. Created by Celtic monks around 800 AD, it's a masterpiece of Western calligraphy and represents one of Ireland's greatest cultural treasures. So, next time, just remember to double-check your spelling before asking, darling.
