Pulley and Sheave
The word as we know it was first in common parlance in Middle English at some time between 1150 to 1500 AD. It was anglicized from the Old French(800-1400 AD) word, "polie." The French likely nabbed it from the Medieval Greek(400-1400 AD) word, polos, which means "pivot" or "axis".

PULLEY
The word as we know it was first in common parlance in Middle English at some time between 1150 to 1500 AD. It was anglicized from the Old French(800-1400 AD) word, "polie." The French likely nabbed it from the Medieval Greek(400-1400 AD) word, polos, which means "pivot" or "axis". Prior to that, we can't be certain what they were called. Since this particular simple machine has been around since at least 200 BC, we can bet there is more to this story.
