Three volumes: Volumes one and two are the complete text of John Payne's translation revised and annotated by Charles S. Singleton, eg Rustico and Alibech's enthusiastic endeavours to put the Devil back in Hell – day three, the tenth story – are now translated in full; volume three contains Singleton's notes and commentary; begun in 1348 during an outbreak of plague in Florence, completed in 1353, and I wonder whether it has always been in print since, even in truncated form.
