Encyclopedia compiled at Constantinople in the mid-ninth century
The Etymologicum Genuinum (standard abbreviation E Gen or EtGen) is the conventional modern title given to a lexical encyclopedia compiled at Constantinople in the mid-ninth century. The anonymous compiler drew on the works of numerous earlier lexicographers and scholiasts, both ancient and recent, including Aelius Herodianus, Georgius Choeroboscus, Saint Methodius, Orion of Thebes, Oros of Alexandria and Theognostus the Grammarian. The "Etymologicum Genuinum" was possibly a product of the intellectual circle around Photius. It was an important source for the subsequent Byzantine lexicographical tradition, including the "Etymologicum Magnum", "Etymologicum Gudianum" and "Etymologicum Symeonis".
Modern scholarship discovered the "Etymologicum Genuinum" only in the nineteenth century. It is preserved in two tenth-century manuscripts, "Codex Vaticanus Graecus" 1818 (= A) and "Codex Laurentianus Sancti Marci" 304 (= B; AD 994). Neither contains the earliest recension nor the complete text, but rather two different abridgements. The manuscript evidence and citations in later works suggest that the original title was simply τὸ Ἐτυμολογικόν and later τὸ μέγα Ἐτυμολογικόν. Its modern name was coined in 1897 by Richard Reitzenstein, who was the first to edit a sample section. The "Etymologicum Genuinum" remains for the most part unpublished except for specimen glosses. Two editions are in long-term preparation, one begun by Ada Adler and continued by Klaus Alpers, the other by François Lasserre and Nikolaos Livadaras. The latter edition is published under the title "Etymologicum Magnum Genuinum", but this designation is not widely used and is a potential source of confusion with the twelfth-century lexical compendium conventionally titled the "Etymologicum Magnum".
