The Origin of Measurement: Ancient Weighing in Early Trade and Industry

The earliest known scales date back to ancient civilizations such as the Egyptians and Romans. Evidence of scales has also been found in the Indus River Valley, around 2000 BC. These early instruments were typically balances, consisting of a beam with a pivot point and two pans suspended from each end. The ancient Egyptians used scales for trade and transactions, and also attributed symbolic and spiritual importance to them. The Romans also employed them for trade, taxation, and coinage. In ancient times, merchants relied on these primitive devices to assess the value of goods in barter. The close relationship between weighing and trade in these early times underscores their pivotal role in economic development. The inclusion of scales in religious beliefs, such as the Egyptian goddess Maat weighing hearts, highlights the perceived importance of fairness and accurate measurement in primitive societies. The need to objectively determine value drove the development and use of these early tools.

Medieval and Renaissance Advances: Towards Greater Precision

During the Medieval and Renaissance periods, more precise scales were developed. Beam scales, which used a lever system, increased precision and accuracy. The invention of the stater in the 16th century allowed for even greater accuracy in weighing objects. Coin-operated weighing machines became popular, allowing merchants to charge customers based on the weight of their goods. In the 15th century, Leonardo da Vinci invented the first automatic balance with a graduated scale. The move toward more precise scales during this era indicates a growing need for accuracy in commerce and, possibly, in emerging industrial activities. The invention of the automatic balance represented a significant step toward more efficient and reliable measurements.

The Industrial Revolution: A Turning Point for Industrial Scales
