angels dancing on the head of a pin
An allusion to the theological question “How many angels can dance on the head of a pin?” — a question cited to debunk mediaeval angelology in particular and scholasticism in general. Since angels are non-corporeal and do not occupy space, an infinite number of them could be present at a single point in space simultaneously.
- (figuratively) The subject of arcane intellectual speculation; used as an example subject of enquiry the pursuit of which is of no value.
