Waving one's hands can mean avoiding details or drawing attention away from a lie of an unsupported part of an argument or story. There is an entire Wikipedia article on the topic if you want more detail.
I would like to know how to wave hands in classical Latin. More precisely:
- Does any direct translation of waving hands (like manus iactare) have an idiomatic non-literal meaning?
- What would be a good way to express hand-waving in classical Latin? Is there a verb, noun, or other phrase that captures the idea?
