As for the others, Jacque Vaché overdosed on opium, the intentionality of which remains in dispute, while Cravan and Torma both simply disappeared, appropriately so, as they were certainly the most cryptic of the bunch.
Cravan was clearly a skilled riter, but perhaps too distracted by living life to devote enough time to his craft.
In addition to a few letters to Daumal and others, he is represented here by the firs of his two published books, Euphorisms, a collection of notes and observations characterized by a condescending, world-weary nihilism sprinkled liberally with word play, some of which was apparently too complex to translate.
The only writer Torma appeared to respect is Alfred Jarry, whose various pataphysical writings he often references.Jacques Vaché was a good friend of and influence on André Breton, but died before Dadaism even came into being.
His writing here is solely restricted to letters, which Breton later collected and published after his death.
