as this could not have been very favourable to the preservation of the books themselves. They, however, had a certain amount of protection which was denied to their readers, for they were shut up in presses. The word used for these, armarium, is the same as that which was applied by the Romans to their bookcases; and probably the idea of such a piece of furniture was due to a far-off echo of ancient usage.
