Ups & Downs: The Evolution of Elevators:

The need to move things to the next level has been recognized for thousands of years. Elevators have a long history, going from a platform attached to a rope pulled by a human to the smooth, electric rides in boxes that we now enjoy.
Vertical lifts may have been used to build the pyramids in Egypt. However, the first recorded use came in the third century B.C., according to Elevator History. Archimedes, the Greek mathematician, physicist and astronomer, is typically credited with inventing the first known elevator, according to Landmark Elevator. His device was operated by ropes and pulleys. The ropes were coiled around a winding drum by a capstan and levers, according to Otis World Wide. These early lifts, or hoists, powered by people, animals or water, were primarily used to lift heavy loads, such as water or building materials.
Crude elevator systems lifted people as early as the first century A.D, according to Otis. The Roman Coliseum used lifts to raise gladiators and wild animals up from the lower levels to the arena level. In medieval times, hoists were the only way to get to the monastery in St. Barlaam, Greece, which stood on a pinnacle about 200 feet (60 meters) off the ground.
