[3] Georg Johannesen's entered the literary scene with a novel, Høst i mars ( (1957), a tender love story with a tragic denouement about romance in the face of bourgeois prejudice.

The second collection, Ars moriendi (1965), is structured around a rigid formal arrangement inspired by the Seven deadly sins of Christianity.

The play was attacked for its blasphemous content and caused an uproar when it was first performed at the Det Norske Teatret.

The Norwegian drilling for offshore oil was presented in a satirical manner in the novel Mongstad (1989), which Johannesen published under the pseudonym Kathy Johns.

Both his plays and his poems bear evidence of inspiration from the work of German dramatist and poet, Bertolt Brecht (1898–1956).
