I just saw a review of a soon-to-be-released book called Reckless Rites . I'm curious to hear more about it, if anyone reads it or knows anything about it.
UPDATE: It appears that Horowitz had an earlier article on the topic which appeared in Poetics Today 15,1 (1994) 9-54 1994 entitled "The rite to be reckless; on the perpetration and interpretation of Purim violence". It is available on JSTOR, if you have a subscription.
Hat tip for the article: Dan.
