The oldest "living" encyclopedia, over a thousand years old, made from ancient and medieval materials, one of the most valuable sources for ancient scholars, historical researchers, philologists, linguists, and archaeologists. Extensive in scope, with a multifaceted structure, it was an ambitious work that aimed to encompass "all ages and all genres of philology" - a true treasure trove.
Its author, a greedy lover - and collector - of the written word, without making any distinction between ancient and medieval Greek language, between rare words and literary phrases and common words and expressions, above all, was interested in enriching it with a large number of entries, drawing from previous lexicographic works, with the aim of covering the encyclopedic interests of its readers.
