Armarium

The armarium was generally placed in the atrium of the house.

Professor Clark also quotes from the Customs of the Augustinian Order, which required that the armarium be "lined inside with wood, that the damp of the walls may not moisten or stain the books," […]

An earlier example of an armarium (AD 424—450) appears in a representation of St Lawrence in the Mausoleum of Galla Placidia, Ravenna, for which see Kitzinger, fig. 95.

You can see evidence of this activity: in the south wall is the armarium where the monks kept their books.

The proventriculus of both the Blattaria and Isoptera conforms to the basic orthopteran plan and consists of an anterior armarium and the posterior stomodaeal valve; the armarium tapers posteriorly as it merges with the narrow valve.

The proventriculi of both Arenivaga bolliana and Hypercomps fieberi appear to lack the anterior dental belt of the armarium; otherwise, they are dissimilar.

The sclerotized portion of the proventriculus (armarium) has six cuticular folds each armed with a tooth for crushing food and a pulvillus bearing hairs which forms a fine filter.

Anteriorly it bears an armarium and posteriosly^([sic]) a stomodaeal valve.
