In the context of guilds and craft production, a master is a skilled artisan who has completed extensive training and holds the highest status within a specific trade. Masters not only possess advanced knowledge and expertise in their craft but also oversee apprentices and journeymen, ensuring the quality of work and maintaining the standards set by the guild. Their role is crucial in the organization of craft production, as they contribute to both the economic success of their trade and the regulation of craftsmanship within the guild system.
