Byzantium plays a vital role for the transmission of ancient, late antique and Medieval Greek texts. Thousands of manuscripts preserved in libraries and collections are full of texts of ancient tragedians, late antique church fathers and particularly of Biblical texts, which represent the lions share of transmitted manuscripts. A considerable number of manuscripts, depending on the setting in which they were copied, are equipped with illuminations or various kinds of ornamentation which increase their value. These often very elaborately and colorfully designed depictions are usually accompanied by texts, which, due to not belonging to the main text of the manuscript, are called paratexts. A considerable number of these paratexts are in verse form. Such texts, called book epigrams, fulfill various functions: they explain the depicted scenes, highlight the relationship between the manuscripts main text and the illumination, or act themselves as images, as for example when the text of the epigram is written in the shape of a cross or inscribed into an ornamental frame. Many of these texts, considered purely on visual grounds, already resemble inscriptions which are preserved on other kinds of surfaces and objects. The current volume is structured like the preceding three volumes of the series Byzantine epigrams on objects, which have so far presented inscriptional verses on frescoes and mosaics; icons and portable objects; and on stones. The publications focus is on critical editions of the texts, (German) translations of the Greek texts, and commentaries. Besides general chapters on the cultural-historical phenomenon of quasi-inscriptional verses in manuscripts, paleography, language etc., almost all the epigrams treated are also depicted in the volumes collection of plates in order to facilitate study of the original context of the verses.
