The Book of Kells (Irish: Leabhar Cheanannais) (Dublin, Trinity College Library, MS A. I. (58), sometimes known as the Book of Columba) is an illuminated manuscript that is a masterwork of Western calligraphy and represents the pinnacle of Insular illumination. It is also widely regarded as Ireland's finest national treasure. Transcribed by Celtic monks ca. 800, it contains the four Gospels of the New Testament in Latin, together with various prefatory texts and tables. The text of the Gospels is largely drawn from the Vulgate, although it also includes several passage drawn from the earlier versions of the Bible known as the Vetus Latina.The illustrations and ornamentation of the Book of Kells surpasses that of other Insular Gospels in extravagance and complexity. The decoration combines traditional Christian iconography with the ornate swirling motifs of typical of Insular art. Figures of humans, animals and mythical beasts together with intricate knotwork and interlacing patterns in vibrant colours enliven the manuscript's pages. Many of these minor decorative elements are imbued with Christian symbolism and so further emphasize the themes of the major illustrations.
