Aren Maeir of Bar-Ilan University and Philipp Stockhammer of the Max Planck Institute have pulled together every excavated grave and cemetery known from Iron Age Philistia for a wide-ranging article in ‘Atiqot 117. The most startling observation comes from a salvage dig at Tel ‘Erani, where micro-remains trapped in dental plaque reveal that at least some of the interred consumed banana—alongside sesame and millet—foods that did not grow in the Levant during the period. The authors conclude that the evidence “proves the existence of long-range trade between the Levant and distant regions around 1000 BCE,” countering older views that international exchange collapsed after the Late Bronze Age crisis .
Exotic diet evidence
Forty-three simple pit graves were dug through an earlier Early Bronze fortification wall at Tel ‘Erani. Although the cemetery straddles the Philistine frontier, botanical and isotopic study of dental calculus documented banana starch granules and other non-local food residues in several individuals . The plant signals indicate either the import of dried fruit—possibly by maritime traders arriving from South Asia—or experimental cultivation undertaken with imported propagules. Either scenario places Iron Age Philistia within a far-flung commercial web previously attested only for later centuries.
Where are the adults?
Across the Philistine heartland, visible graves are surprisingly scarce for the twelfth–eleventh centuries BCE. Extensive excavation in Ashqelon, Ashdod and Tell eṣ-Ṣafi/Gat has exposed scores of intramural infant jar burials yet almost no adult interments. Maeir and Stockhammer argue that the gap reflects conscious adoption of burial modes that leave little archaeological trace—disposal at sea, exposure, cremation with ash scattering—possibly developed during the migrants’ journey from the Aegean and maintained to distinguish the newcomers from Canaanite neighbours .
Visible customs in context
When graves do appear, they are highly varied. Infant jar burials re-emerge after a millennium-long hiatus and cluster in the earliest Iron Age strata at Ashqelon, Tel Miqne-Ekron and Gat . Multigenerational rock-cut tombs, typical of Canaanite tradition, are limited to Niẓẓanim and Tell el-Far‘ah (S), suggesting those caves served local groups rather than Philistine settlers . A large extramural cemetery north of Ashqelon, active from Iron IIA to IIB, combines pit, cist and cremation burials influenced by Phoenician practice; adults dominate the sample, but genetic analysis shows their ancestry aligns with Southern Levant populations rather than the Aegean signature seen in Ashqelon’s early infant burials .
Interpreting the “invisible deathscape”
The authors frame Philistia’s mortuary record as a spectrum ranging from archaeologically “visible” practices—jar burials, pit graves, cremations—to “invisible” rites that erased material traces. They suggest that migrant Philistines may have chosen low-visibility treatments for adults to reinforce group identity or respond pragmatically to mobile lifeways. The revival of jar burials for infants could, conversely, mark households and social boundaries inside the new urban fabric .
By bringing together chemical, biological and cultural data, the study shows that Philistia was both more outward-looking and more internally diverse than previously thought. Banana residues anchor an intercontinental trade corridor at least a century earlier than any textual reference, while the pattern of missing adult tombs forces a reconsideration of how archaeologists read absence in the record. As Maeir and Stockhammer note, “there is not a single burial which… may be unanimously and undoubtedly identified as Philistine,” but the combination of exotic diets and selective visibility paints a nuanced picture of a society negotiating identity through its dead .
The authors call for targeted excavations in peripheral zones and undisturbed contexts, predicting that additional lines of evidence—especially biomolecular—will refine the emerging map of Iron Age networks that once connected the Judean plain to the Indian Ocean.
