Here’s a rare poster from Apollon 1897 tour of Germany. Unsurprisingly, heavy supporting lifts were the norm as they allowed rather impressive weights (and types of weights) to be used. It was probably Sandow who began this practice, lifting a horse with one arm and walking across the stage. As far as lifting bicycles and their riders, this feat made appearances for many years to come, (check out this and this.)
We couldn’t find much in our files about Mr. Barletti but the one thing we do know is that he liked to lift horses as a part of his act. He most likely copied this feat from Sandow, and I’d be willing to bet it wasn’t exactly done on stage like it is pictured here.
