Input (English): In one play by this writer, Pelasgus allows a group of women to gain shelter in Argos. That work originally was part of the Danaid Tetralogy. Aristotle credited him for adding a second actor in addition to the chorus to his plays, and some of the fragments attributed to him include Nereids and Proteus. A group of plays he wrote ends with a murder trial argued by Apollo and leading to a renaming of the Furies. That murder trial is for the death of Aegisthus and Clytemnetra at the hands of Orestes. Name this playwright of The Suppliants, The Persians, and Seven Against Thebes, whose Agamemnon begins his Oresteia trilogy.
