Another type of pottery—a local variation of monochrome Mycenaean IIIC:1b pottery—has to be taken into account. This pottery is derived from Aegean/Mycenaean pottery, and is typologically a forerunner of Philistine painted bichrome pottery. Its appearance in Tel Ashdod and Tel Miqne (ancient Ekron) led Trude and Moshe Dothan, the excavators of these sites, to conclude that this class of pottery represents an earlier wave of invading Sea Peoples into the country at the end of the 13th century B.C. However, the presently available data—first and foremost the fact that this pottery was used concurrently with painted Philistine pottery in these sites—makes the adoption of such a theory very difficult.
