Final answer:
In Plato's 'Protagoras', Prometheus is portrayed as a 'first finder', providing humans with essential skills and knowledge, symbolizing civilization's advancement.
Step-by-step explanation:
In Plato's dialogue Protagoras, Prometheus is portrayed as a 'first finder' in the sense that he is credited with giving humans the skills and knowledge necessary to survive and progress. Prometheus's role as a benefactor to humanity exemplifies the concept of the 'first finder,' someone who discovers or bestows new knowledge or technology upon humanity. In a myth recounted within the dialogue, Prometheus gives humans fire and various crafts, symbolizing the advancement of civilization. This contribution ultimately separates humanity from the animal world and sets the stage for the development of cities, laws, and politics, which is central to the discussion of virtue and knowledge in the Protagoras.
