Atomic bombings of Hiroshima and Nagasaki
In his 1964 poetry collection "Lux aeterna", Ó Tuairisc included a long poem inspired by the Atomic bombings of Hiroshima and Nagasaki, entitled "Aifreann na marbh" ("Mass for the Dead"). The poem is an imitation of the Roman Catholic Requiem Mass, "with the significant omission of 'Credo' and 'Gloria.'"
