An Egyptian wall-painting in the tomb of Hesy-Ra, dating to 2600 BC, shows a wooden tub made of staves, bound together with wooden hoops, and used to measure corn. Another Egyptian tomb painting dating to 1900 BC shows a cooper and tubs made of staves in use at the grape harvest. Palm-wood casks were also reported in use in ancient Babylon. In Europe, buckets and casks dating to 200 BC have been found preserved in the mud of lake villages. A lake village near Glastonbury dating to the late Iron Age has yielded one complete tub and a number of wooden staves. The Roman historian Pliny the Elder reports that cooperage in Europe originated with the Gauls in Alpine villages where they stored their beverages in wooden casks bound with hoops. Pliny identified three different types of coopers: ordinary coopers, wine coopers and coopers who made large casks. Large casks contained staves that were larger and more numerous and were corresponding more difficulty to assemble. Roman coopers tended to be independent tradesmen, passing their skills on to their sons. The Greek geographer Strabo records wooden pithoi were lined with pitch to stop leakage and preserve the wine.
