The miniature from folio 90 depicts St Romuald Enthroned with Four Saints in an initial O. This initial begins the introit to the Mass for the feast of St Romuald (June 19, according to the Camaldolese calendar). The richly ornamented initial in the shape of a floral garland opens into a well-defined picture space, where St Romuald sits on an ornate tabernacle throne. The founder of the Camaldolese order is surrounded by a bishop saint, possibly St Augustine, and three monastic saints wearing Camaldolese habits.
