We can actually visualize three possible routes across the Sinai peninsula - the northern route proceeding east (via Sirbonis) and then southeast; another following out
of Egypt a generally easterly direction through, roughly, the central part
of the Sinaitic
triangle; and a
third route taking the Israelites in a southeasterly march toward the lower
point of the peninsula and the traditional location
of Mount Sinai.
Other times it's because their role is «soft» — romantic dramas tend to be tough for men to win attention for, hence nobody really considering Charlie Cox's work in The Theory
of Everything as a performance just as the
third point in a
triangle.
