But in the thirteenth century and before it, Psalters were in use for this purpose, and the collation of a Psalter is in truth more important than that of a Book of Hours. It will be well for a student, therefore, to begin with Psalters, as he can then get up the Hours in their elementary form. I subjoin a bibliographical account of both kinds of MSS. In the famous Exhibition at the Burlington Club in 1874, a number of volumes was arranged to show how persistent one type of the age could be. The form of the decorations, and the arrangement of the figures in borders, once invented, was fixed for generations. In a Psalter of the thirteenth century there was, under the month of January in the calendar, a picture of a grotesque little figure warming himself at a stove. The hearth below, the chimney-pot above, on which a stork was feeding her brood, with the intermediate chimney shaft used as a border, looked like a scientific preparation from the interior anatomy of a house of the period. In one of the latest of the MSS. exhibited on that occasion was the self-same design again. The little man was no longer a grotesque, and the picture had all the high finish and completeness in drawing that we might expect in the workmanship of a contemporary of Van Eyck. There was a full series of intermediate books, showing the gradual growth of the picture.
