ONE of the special delights of my childh good was to go and see the cases of illuminated manuscripts in the British Museum and to walk, as every child can right into their pages losing myself in an enchanted world of gold, vermilion and cobalt arabesques, of palaces, gardens, landscapes and skies whose colours were indwelt with light as if their sun shone not above but in them. Most marvelous of all were the many manuscripts mysteriously entitled "Books of Hours'*, since I did not know how one kept hours in a book.
