The Romans, who eventually conquered the Greeks and adopted many aspects of their culture, did not adopt the Greek perception of footwear and clothing. Roman clothing was seen as a sign of power, and footwear was seen as a necessity of living in a civilized world, although the slaves and paupers usually went barefoot. Roman soldiers were issued with chiral (left and right shoe different) footwear. There are references to shoes being worn in the Bible.
As civilizations began to develop, thong sandals (the precursors of the modern flip-flop) were worn. This practice dates back to pictures of them in ancient Egyptian murals from 4000 BC. One pair found in Europe was made of papyrus leaves and dated to be approximately 1,500 years old. They were also worn in Jerusalem during the first century of the Common Era. Thong sandals were worn by many civilizations and made from a wide variety of materials. Ancient Egyptian sandals were made from papyrus and palm leaves. The Masai of Africa made them out of rawhide. In India they were made from wood. In China and Japan, rice straw was used. The leaves of the sisal plant were used to make twine for sandals in South America while the natives of Mexico used the Yucca plant.
The first steps towards mechanisation were taken during the Napoleonic Wars by the engineer, Marc Brunel. He developed machinery for the mass-production of boots for the soldiers of the British Army. In 1812 he devised a scheme for making nailed-boot-making machinery that automatically fastened soles to uppers by means of metallic pins or nails. With the support of the Duke of York, the shoes were manufactured, and, due to their strength, cheapness, and durability, were introduced for the use of the army. In the same year, the use of screws and staples was patented by Richard Woodman. Brunel’s system was described by Sir Richard Phillips as a visitor to his factory in Battersea as follows:
