During the mid to late 1910s, Eugene O'Neill wrote a series of one-act plays prior to his first full-length drama, Beyond the Horizon. Four of these realistic one-acts, often referred to as O'Neill's "plays of the sea," were ultimately grouped under the title S. S. Glencairn, the name of the ship on which the four dramas, The Moon of the Caribbees (1918), Bound East for Cardiff (1916), The Long Voyage Home (1917) and In the Zone (1917), are set. The Provincetown Players first staged the plays individually or on bills with works by other playwrights, but the bill called S.S. Glencairn premiered on 3 November 1925 at the Provincetown Playhouse for 105 performances. The bill was revived for 90 additional performances on 9 January 1929 and motion picture director John Ford adapted the plays to the screen as The Long Voyage Home (1940).
