Various Notices on the Sewanee Production of Antigone of 1894

“Loftier than this devotion to the legitimate, semi-legitimate, and wholly illegitimate drama, is the success on the stage of the students of the Greek department, who, under the direction of Vice Chancellor Wiggins, have won an enviable reputation by their presentations of the masterpieces of ancient tragedy and comedy. Every summer they put a Greek play on the boards, now a comedy of Aristophanes, that makes the audience hold its sides with laughter; now a solemn and moving tragedy of Sophocles or Euripides that brings tears to the eyes of seasoned veterans. The performance of the “Antigone” last summer elicited great enthusiasm, not only at Sewanee, where it was presented before a large and distinguished audience, but also at Nashville, where two brilliant performances were given in the opera house. So great is the interest aroused by this successful reproduction of the spirit of old Greek life as exhibited in the Greek drama, that the Greek play may be said to be the leading feature of a Sewanee commencement—a function which lasts several days, a performance at which there is no vacant seat, and a marvel of staging considering the primitive surroundings of the University.”
