It is not imported pottery — it was locally made, using local clays, but in the Aegean style.

This means it was made by people who knew how to make Aegean-style pottery but were doing so in a new location.

The most natural interpretation is that the people making this pottery came from the Aegean — specifically, from a cultural tradition rooted in the Mycenaean world.

But this raises a question: if the Philistines (Peleset) came from the Aegean, why does the Egyptian relief at Medinet Habu show them with feathered headdresses that do not obviously correspond to anything known from Mycenaean material culture?

The answer may be that the feathered headdress was a regional marker of a specific Aegean group — perhaps from the coast of Anatolia or a transitional zone between the Aegean and the Near East — rather than a uniquely Mycenaean element.
