Around the first time I ever knew of anybody playing a cello, I thought that instrument was invented for violinists who had played so long as to wear out their chin and shoulder and therefore could no longer hold a violin in the normal position for any length of time. A cello was essentially the same instrument, I thought, designed to rest on the floor so they could continue to play it after their chin and shoulder were worn out. I hadn't yet learned back then about different sized instruments having different pitch ranges.
