With My Dog Eyes by Hilda Hilst (fiction originally published in 1986)

I had never heard of this Brazilian avant-garde author but recognized the "dog eyes" reference to Clytemnestra, so I tried this short book.  It's about a mathematics professor who goes crazy, and it is very very good, funny sad and weird.  The translator and author of the introduction, Adam Morris, missed her clear (to me) debt to Nabokov.
