Moving
loads on the backs of people, perhaps using some means of load distribution,
has persisted since the earliest times. The top picture shows an imagined
market place at Dunhuang, along the silk road between China and the Middle East
and Rome. Animals were used for long distance transport but human porters
played an important role in local transportation.
The bottom photograph
shows porters in the mountains of Nepal in 1989. The goods to be transported
are carried in baskets secured to the porters back with a forehead strap.
An individual load might be as much as 100 kg! |
