1. (obs) (rare) A pompous person who pretends to have inspiration or spiritual insight.
(Jonathan Swift is credited with first using this term in English literature in 1704 in Tale of a Tub: "The learned Aeolists maintain the original cause of all things to be wind.").
The irony is that an aeolist pretends to have inspiration. If one researches the etymology of inspiration > Old French inspiracion "inhaling, breathing in; inspiration,"> Late Latin inspirationem noun of action from past participle stem of Latin inspirare "inspire, inflame, blow into." Therefore, an aeolist really is full of wind.
I did a search on the 'Net for Aeolist, and there are actually companies that have chosen that for their names...Not sure that is such a great brand name...And, s/one used it on FB as his/her screen name (now, that might tell you that person tends to go on and on and might not be s/one to "friend"). I love researching obsolete words or words that have undergone a shift in definition from the time they entered the English language (handsome and handy).
