===San Giovanni Evangelista, Rimini===
At this church whose patron was [[Galla Placidia]] (died 450), paired rectangular chambers flanking the apse, accessible only from each aisle, have been interpreted as paired (Latin and Greek) libraries and perhaps scriptoria.<ref>Janet Charlotte Smith, "The Side Chambers of San Giovanni Evangelista in Ravenna: Church Libraries of the Fifth Century" ''Gesta,'' '''29'''.1 (1990): 86–97)</ref> The well-lit niches half a meter deep, provisions for [[hypocaust]]s beneath the floors to keep the spaces dry, have prototypes in the architecture of Roman libraries.<ref>E.
