The Care of Books
“ A representation of rolls arranged on the system which I have attempted to describe, occurs on a piece of sculpture (fig. 11) found at Neumagen near Trèves in the seventeenth century, among the ruins of a fortified camp attributed to Constantine the Great [87] . Two divisions, full of rolls, are shewn, [35] from which a man, presumably the librarian, is selecting one. The ends of the rolls are furnished with tickets. Fig. 11. A Roman taking down a roll from its place in a library. The system of pigeon-holes terminated, in all probability, in a cornice. ”
