What do you guys think this scenario would look like? Say the portal to Equestria opens up for a couple decades, allowing Phoenician and Greek ships to travel to and fro, and set up a couple of colonies somewhere in the continent before it closes permanently.

In what time period do you guys think would be most interesting for this to take place?

What do you guys think would be the best place for them to settle?

How do you guys think the inhabitants would react?

How do you figure it would affect Equestria's history?
