As previously mentioned, today, Prof. Eliezer Oren (BGU) gave a talk at BIU on a reappraisal of the Sea Peoples burials at Beth Shean, a generation after the publication of his book on the northern cemetery of Beth Shean.
After first surveying the background of the Egyptian presence in Canaan in the LB and early Iron Age and the finds at Beth Shean, Prof. Oren discussed the anthropomorphic coffins found at various sites in the Levant and Egypt and noted that in the past it had been suggested that they were all related to the Philistines. Showing that this cannot be, he stressed that he nevertheless believes that the 5 so-called “grotesque” coffins at Beth Shean should be related to the Sea Peoples/Philistines, in light of their similarities to the depictions of the headdresses of the Sea Peoples in the Medinet Habu reliefs.
He then showed that all the parallels to the so-called feather head dress of the Sea Peoples in fact dates to the early Iron Age, and claimed that one cannot find earlier Aegean antecedents to this. This is interesting, since if so, means that this headdress was not a typical Aegean attire in the LB.
This is an interesting point, but as I pointed out to him in the questions there is a similar depiction of people with a similar headdress in the Phaistos disk.
In any case, it was an interesting review of these well-known finds, and with an important reassessment of various aspects relating to these coffins.
