In 1938, entering a literary contest of the nigerian education ministry, fagunwa wrote his ogboju ?d? ninu igbo irunmal??, widely considered the first novel written in the yoruba language and one of the first to be written in any african language. wole soyinka translated the book into english in 1968 as the forest of a thousand daemons, first published by random house and again by city lights in september 2013 (isbn 9780872866300). fagunwa's later works include igbo olodumare (the forest of god, 1949), ireke onibudo (1949), irinkerindo ninu igbo elegbeje (expedition to the mount of thought, 1954), and adiitu olodumare (1961).
fagunwa's novels draw heavily on folktale traditions and idioms, including many supernatural elements. his heroes are usually yoruba hunters, who interact with kings, sages, and even gods in their quests.
