The interiors of medieval churches were adorned with magnificent tapestries, finely painted banners, subtly embroidered altar hangings and the liturgical vestments worn by the clergy. Movable by their very nature, textiles could easily be taken down and replaced by others more appropriate to the individual feasts celebrated throughout the liturgical year. The 2012 special exhibition presents such ornamenta, as these decorative textiles were known, and explains their function and iconography.
