I want to know the answer to the following question:
What against did Metzinger and Gleizes write Du "Cubsime"?
All the background I'm provided with is that "It was against this background of public anger that Jean Metzinger and Albert Gleizes wrote Du "Cubisme" (published by Eugène Figuière in 1912, translated to English and Russian in 1913).". Is that enough to answer the question?
Answer: yes
