Seeing into the ‘Stone Age’: The stone tools of early man

Bob Markham (UK) In the early part of his evolution, man made great use of rock and stone to assist him in his activities. The term ‘Stone Age’ has been given to the period of time during which stone was the main material used for the manufacture of functional tools for daily life. It is generally thought to have commenced about 3.3Ma and was the time when man firmly established his position on earth as a ‘tool-using’ mammal. However, it should be remembered that stone was not the only material used for this purpose. More perishable materials, such as wood, reeds, bone and antler, were also used, but very few of these materials have survived to be found today (but see the box: Non-stone tools). Non-stone toolsA notable exception to the general rule that non-stone tools have not been preserved is the Palaeolithic wooden spear shaft that was recovered in 1911 from a site in Clacton in Essex. At 400,000 years old, the yew-wood spear is the oldest, wooden artefact that is known to have been found in the UK (see http://piclib.nhm.ac.uk/results.asp?image=001066).A number of wooden spears dating from 380,000 to 400,000 years ago were also recovered between 1994 and 1998 from an open-cast coal mine in Germany (see https://en.wikipedia.org/wiki/Schoningen_Spears). Other items are found from time to time from peat-bog conditions, which offer the most favourable medium for the preservation of such material.The stones used to make tools Being a non-perishable material, stone has survived the ravages of time and is … Read More

Mining in ancient Greece and Rome

Dr Robert Sturm (Austria) Ancient civilizations had a high demand for raw materials, like clay, diverse rocks and, most of all, metals. These were required for buildings, crafts, agriculture, their armed forces, financial concerns, art and culture. Clays and rocks produced by opencast mining primarily served for the production of bricks and building blocks, which were used for civil and hydraulic engineering. They were additionally extracted for the manufacture of durable goods and art objects, such as dishes and statues. Metals – like gold, silver, copper, tin, iron and lead – being essential raw materials in antique civilisations, were commonly produced by underground mining. Gold and silver were mostly used as raw material for ancient coins. The use of noble metals in monetary economy has been going on since the seventh century BC, when barter trade was successively replaced by a monetary economy. Copper, tin and iron was mostly produced for the manufacture of arms, whereas lead was, among other things, used for the production of water conduits and as a stain for ornamental painting. Fig. 1. Some examples for the use of metals: lead was, among other things, used as stain for ornamental painting (left), whereas silver was used for coins (right). Ancient techniques used for the mining of raw materials Sufficient supplies of metallic and mineral raw materials required systematic mining, since only gold was found in large enough amounts in washes of brooks and rivers to make panning worthwhile. Other metals usually occurred as chemical components of … Read More
