20th-18th century BC. A pillow-shaped clay tablet with a field plan to one side, the other side with calculations regarding the plan; accompanied by a copy of a handwritten scholarly note which states: 'Field Plan. 76mm x 50mm. Old Babylonian, Ca. 2000-1800 BC. This shows two field plots on the obverse with their length and width measurements given along their edges. The reverse contains calculations based on these measurements concerning areas and related agricultural matters. With further endeavour more sense could be made of this tablet but it probably represents a school exercise, as it is known that the trainee scribes had to practice such calculations.' 120 grams, 80mm (3").
