This situation changed abruptly in 1907, with the discovery of the Cairo Codex, which contained large parts of the Samia; the Perikeiromene; the Epitrepontes; a section of the Heros; and another fragment from an unidentified play.
A fragment of 115 lines of the Sikyonioi had been found in the papier mache of a mummy case in 1906.

In 1959, the Bodmer papyrus was published containing Dyskolos, more of the Samia, and half of the Aspis.
In the late 1960s, more of the Sikyonioi was found as filling for two more mummy cases; this proved to be drawn from the same manuscript as the discovery in 1906, which had clearly been thoroughly recycled.

Other papyrus fragments continue to be discovered and published.

In 2003, a palimpsest manuscript, in Syriac writing of the 9th century, was found where the reused parchment comes from a very expensive 4th-century Greek manuscript of works by Menander.
 The surviving leaves contain parts of the Dyskolos and 200 lines of another, so far unidentified, piece by Menander.
