Dynamic Splendor introduces a cycle of sixth-century mosaics little known to scholars, though they are comparable in quality and interest to famed mosaics in Italy and elsewhere. Ann Terry and Henry Maguire provide the first comprehensive account of the history and meaning of the mosaics along with the first high-quality photographic documentation of the ensemble.

It has only recently been possible to study the mosaics at Porec closely, due to favorable conditions in Croatian Istria, where the mosaics reside, and to the discovery of the original restoration documents in Vienna and Trieste. Terry and Maguire have tracked the condition and restoration of these works, distinguishing between the original mosaics and later contributions. Beyond creating an important archival source, the authors consider the making of the mosaics, their thematic structure, their relationship to the cathedral complex, and their connection to the patron, Bishop Eufrasius, while drawing parallels with other renowned works.
