PREFACE.

The object of this book is to give a general account of the various methods of writing, the different forms of manuscripts and the styles and systems of decoration that were used from the earliest times down to the sixteenth century A.D., when the invention of printing gradually put an end to the ancient and beautiful art of manuscript illumination.

I have attempted to give a historical sketch of the growth and development of the various styles of manuscript illumination, and also of the chief technical processes which were employed in the preparation of pigments, the application of gold leaf, and other details, to which the most unsparing amount of time and labour was devoted by the scribes and illuminators of many different countries and periods.

An important point with regard to this subject is the remarkable way in which technical processes lasted, in many cases, almost without alteration from classical times down to the latest mediaeval period, partly owing to the existence of an unbroken chain of traditional practice, and partly on account of the mediaeval custom of studying and obeying the precepts of such classical writers as Vitruvius and Pliny the Elder.

To an English student the art-history of illuminated manuscripts should be especially interesting, as there were two distinct periods when the productions of English illuminators were of unrivalled beauty and importance throughout the world^[1].

In the latter part of this volume I have tried to describe the conditions under which the illuminators of manuscripts did their work, whether they were monks who laboured in the scriptorium of a monastery, or members of some secular guild, such as the great painters' guilds of Bruges or Paris.

The extraordinary beauty and marvellous technical perfection of certain classes of manuscripts make it
