The Book of Kells
about AD 800 Iona (Scotland) and Kells (Ireland); now in Dublin
In short
The Book of Kells contains the four Gospels in Latin and is decorated in an extraordinary way. It was made by Irish or Scottish monks, perhaps started in the monastery of Iona and finished at Kells, in Ireland. Its pages are full of knotwork, spirals, fantastic animals and opening letters so detailed that you need a magnifying glass to see everything. Today it is kept in the library of Trinity College Dublin.
Why it matters It is considered one of the masterpieces of illuminated books, decorated by hand, of the Middle Ages.

The story
Irish monks on a Scottish island
In 563 an Irish monk, Columba (in Irish Colum Cille), landed with twelve companions on the island of Iona, a small islet of rock and meadow off the west of Scotland, and founded a monastery there. From there the monks set out to bring Christianity to the peoples of Scotland and northern England, and they made Iona one of the most important centres of culture of the age. The Irish monks were famous for their skill in copying books and for their eagerness to teach.
In the British Isles and Ireland, after the fall of the Roman Empire, a style of art all of their own had developed, called Insular: spirals, knots and interlacing lines that never end, stretched and twisted animals, stylised faces. It combined the traditions of Celtic art and of the Germanic peoples with models from Mediterranean Christianity.
A book for the altar
Around the year 800, perhaps at Iona, perhaps in another monastery, a group of monks began to copy the four Gospels, that is, the accounts of the life of Jesus, in a splendid volume. It was a book for the altar, meant not to be read every day but to stay in the church on the great feast days. The monks wrote the Latin text with an ink made from oak galls and iron sulphate, in a clear, regular script called Insular uncial.
For the parchment they used calfskin: according to scholars' calculations, the skins of about one hundred and eighty to one hundred and eighty-five calves were needed. The pages were sheets about thirty-three centimetres wide. The book today has 340 leaves, that is, 680 pages, but some of it has probably been lost.
Colour and imagination
What marks out the Book of Kells is its decoration. Almost every page has giant initial letters, interlacing, animals and human figures, brightly coloured with pigments made from minerals and plants: yellow from orpiment, green from verdigris, blue from woad or from other plant pigments. There is hardly any empty space. Some pages show portraits of the four evangelists, the Virgin Mary with the infant Jesus and the scene of the temptation of Jesus.
The most famous page is the one called “Chi-Rho”, where the first Greek letters of the name of Christ, X (chi) and P (rho), fill the whole page, with spirals, knots and hidden figures. If you look closely, you find tiny animals among the interlacing: cats, mice nibbling a communion wafer, otters with a fish, butterflies. The monks, clearly, liked a joke too.
Who made the book? Scholars recognise at least three or four different hands of scribes and decorators, who perhaps worked for years. The text is copied with some mistakes and with some lines left blank, a sign that the monks sometimes rushed or let themselves be distracted by the beauty of the decoration, which sometimes takes precedence over the text.
A book that nearly got lost
In 806 the Vikings attacked Iona and killed sixty-eight monks. The survivors took refuge in Ireland, at Kells (in Irish Ceanannas Mór), in County Meath, and probably took the book with them, or finished it there. It took its name from this place. In 1007 the book was stolen from the church at Kells: the thieves tore off the precious gold cover and left it under a heap of earth. It was found a few months later, damaged but still almost whole, according to the Irish annals.
Since 1661 it has been at Trinity College, Dublin, which received it as a gift. Today it is on show in the Old Library, and it is one of the most visited treasures of Ireland. To protect it, since 1953 it has been bound in four volumes, two of which are shown to the public, opened at different pages in rotation. An Irish animated film, “The Secret of Kells” (2009), tells a fantasy story about it.
Why it happened
In Irish monasteries copying books was considered sacred work, and the monks had time, patience and a rich artistic tradition. For the great feasts they needed a book worthy of the importance of the Gospels, rich in colour and gold.
The rich Insular style and contacts with the peoples of the continent offered the monks models and ideas to blend into something new and original.
What changed
The Book of Kells is considered the most beautiful illuminated manuscript of the early Middle Ages and a symbol of Irish identity. It shows the very high level of the art of the monasteries in a period often described as “dark”.
Artists of the time preserved its style in the following centuries, and many Celtic designs today, from jewellery to tattoos, derive from those models.
The book is also an important document for historians: it helps us understand how people worked, which materials they used and how the monks saw the world.
