The extensive corpus of all available legends of Byzantine metrical seals (approx. 4,500) was planned to be published in three volumes; the first two were published in 2011 and 2016, and the third is now available. A fourth volume with addenda is in the works. These miniature epigrams are sometimes aesthetically ambitious and also of philological interest. The commentary makes these seals accessible as an important source for prosopography, social and administrative history, historical geography and art history. This volume contains previously unpublished material as well as suggestions for improvements to seals that have already been published.
