We now know that the epitomes prefixed to the plays of Euripides in the medieval manuscripts were written not for this purpose but as part of a complete collection of Euripidean epitomes, arranged alphabetically by initial,and intended presumably to make the subject-matter of the plays available to persons unable or unwilling to read the plays themselves. The first direct proof of the existence of this collection came with the publication in 1933 of a fragment containing Rhesos, Rhadamanthys, Skyrioi (Gallavotti, Riv. Fil. lxi [1933], 177 fif.; now P.S.I. 1286); we now have parts of it in three other papyri as well (P. Mil. Vogl. 44, with Hippolytos; P. Oxy. 2455, with over twenty plays, including Medea, Orestes, Troades, Phoinissai; P. Oxy. 2457, with Alkestis and Aiolos), and may reasonably suppose that P. Oxy. 420 (Elektra; published in 1903) is also from the same work.
