I recall reading a story by (I think) Stanislaw Lem, about time travel. It was humorous and lightly absurdist, and included an explanation of witches' broomsticks, which he explained as being "time-cycles", looking like witches' broomsticks and making the sound of rattling chains. IIRC the narrator eventually banished all his (incompetent) staff to ancient Greece, where Harris Tottle became Aristotle, etc.
I ask because it might be relevant to a question about witches' broomsticks on worldbuilding.
I searched Lem's site without success.
