Although the Bible cites Dagon as the main Philistine god, there is a stark lack of any evidence indicating the Philistines had any particular proclivity to his worship. In fact, no evidence of Dagon worship whatsoever is discernible at Philistine sites, with even theophoric names invoking the deity being unattested in the already limited corpus of known Philistine names. A further assessment of the Iron Age I finds worship of Dagon in any immediate Canaanite context, let alone one which is indisputably Philistine, as seemingly non-existent.Emanuel, J. P. (2011). Digging for Dagon: A Reassessment of the Archaeological Evidence for a Cult of Philistine Dagon in Iron I Ashdod. In Society of Biblical Literature Annual Meeting. San Francisco, CA. Still, Dagon-worship probably wasn't completely unheard of amongst the Philistines, as multiple mentions of a city known as Beth Dagon in Assyrian, Phoenician, and Egyptian sources may imply the god was venerated in at least some parts of Philistia. Furthermore, the inscription of the sarcophagus of Eshmunazar II, dating to the 6th century BC, calls Jaffa, a Philistine city, one of the "mighty lands of Dagon", though this does little in the way of clarifying the god's importance to the Philistine pantheon.
