Some manuscript images of the technology of the word in the Middle Ages:

First, one of the oldest representations of an armarium or bookcase, from the tomb of Galla Placidia in Ravenna.

Second, we have a rendition of the apostle Matthew at work (insular gospel book, eighth century); compare with the oldest portrait of Augustine, the episcopal authority.

Third, Cassiodorus' own monastery in an eighth century copy of his Institutiones.

Fourth, Cassiodorus or Ezra or somebody at work.

Fifth, Cassiodorus' indexed Psalm commentary

Sixth, the Eusebian canon tables, the earliest form of hypertext hot links.

Seventh, a diagram with arguably mnemonic effects from Cassiodorus' Institutiones.

Eighth, The book as treasure: the Cathach of Columba.

Ninth, The book as glorious self-glorification: from the library of Matthias Corvinus, A. Cortesius' Carmen de Mathiae Corvini Ungariae regis laudibus bellicis, 1487/88.

Finally, a bonus I've not seen myself yet.
