- "It is entirely seemly for a young man killed in battle to lie mangled by the bronze spear. In his death all things appear fair."
Bronze Working provides strong early military units and benefits production. It reveals the Copper resource and, if you have access to Copper, allows you to train Axemen (and Spearmen if you have researched Hunting.) Bronze Working also enables the Slavery civic, which enables hurried production, and lets your Workers chop down forests. Clearance of forest grants a production bonus and opens up land for other improvements.
Evidence of the use of bronze, an alloy of copper and tin, dates back to Thailand in 4500 BC. Several hundred years later, bronze working was discovered in the Middle East. Artifacts from this period show that bronze was initially used for decorative purposes only. This is because tin was not readily available. It wasn't until approximately 2000 BC, when tin was regularly imported from neighboring regions, that bronze replaced copper in the construction of larger items. Bronze was harder and less brittle than copper, and it held a sharper edge. Tools, weapons, and armor made from bronze were also cheaper to produce and more durable. The period of time when bronze was the metal of choice for such items was known as the Bronze Age. The Bronze Age lasted until iron working became prevalent in approximately 1200 BC.
