What was the equivalent of a modern director during medieval times?

In medieval times, the role that most closely resembles the modern director is the Master of Secrets. This individual was responsible for overseeing the production aspects of a performance, which often included managing the narrative, staging, and any technical effects that could enhance the theatrical experience. The Master of Secrets played a crucial role in shaping how the story was told on stage, guiding the actors in their performance and ensuring that the overall vision of the production was realized.

The other roles, such as Choregus, were more related to the organization of the performances and financial aspects, rather than the artistic direction that a modern director would provide. The Lead Actor, while significant in performances, primarily focused on their individual performance rather than directing the overall show. The Stage Manager, although vital in coordinating logistics and managing the production during performances, did not hold the creative and narrative responsibilities associated with direction. Thus, the Master of Secrets stands out as having the key functions akin to a modern director in the theater.
