The scope of this book is best described by the chapter titles: 1) Lindisfarne and Saint Cuthbert 2) The men who made the manuscript 3) The text of the Gospels 4) The script 5) How the manuscript was made 6) The great decorated pages 7) The smaller initials 8) Some comparisons (with contemporary works) 9) The later history of the manuscript
The text is lively, including, for example, an old riddle describing the wax table used for sketches. The Anglo-Saxom instruments used in illuminations are shown in a photograph; you aren't expected to have detailed knowledge of medieval tools. The color plates of the Gospels are magnificant. The art shown for comparison includes not only other manuscripts but metalwork etc.
This book is not only an introduction to the Lindisfarne Gospels but is a good starting point for illuminated manuscripts in general.
