The papyrus Vienna 2.315 of the Rainer collection in the Austrian National Library was first published by Carl Wesseley in 1892. In the 14 rows of text, Wesseley recognised the mutilated fragment of the First Stasimon Melos of Euripides’ Tragoidia Orestes. The seven lines of text are interchanged with musical signs (notations) and in this manner form the partial score of a tragic song for one voice and [?] an instrument. Since the editio princeps of the papyrus, a series of scholars attempted the decipherment and interpretation of the text. In the present paper, these attempts are discussed and new ideas on certain musical symbols are presented. [http://www.vml.de/e/inhalt.php?ISBN=978-3-89646-645-7]
