The pulley is an ancient invention, and its exact origin is not attributed to a single individual. It is believed to have been used as early as 1500 BC in ancient Mesopotamia and later by the Greeks and Romans. Archimedes is often credited with significant advancements in the understanding and application of pulleys around 250 BC. However, the concept of the pulley likely developed over time through contributions from various cultures.
