Pluggé (1938), p.14, lists the first production of a Greek play at Grinnell College as being Euripides' Electra in 1889. Hartigan (1994), p.373, refers to the 1889 production as being Antigone. To add further confusion, Hains (1910), p.29, says that scenes from Oedipus were staged in 1889 (ID 10037), with Sophocles' Electra performed in 1891 (ID 10036), and Antigone in 1909 (ID 4376).
