About 1525 the Venetian Arsenal developed methods of mass-producing warships. These included the frame-first system to replace the Roman hull-first practice. The new system was much faster and required less wood. At the peak of its efficiency the Arsenal employed about 16,000 people who could produce nearly one ship each day, and could fit out, arm, and provision a newly-built galley with standardized parts on a production-line basis not seen again until the Industrial Revolution.
