This study argues that a cluster of first-millennium Anatolian names containing the elements ida-, id-, d-, and ila- reflects a deep-rooted cultural "syndrome" centred on Mt. Ida and preserved in Greek myth, with proposed roots reaching back into the Hittite imperial period. Three lines of inquiry are pursued. First, the title labarna-/laparna- is reinterpreted as a compound la- + -parna- ("house of La"), and the LABARNA-sign (HLuw. L.277) is connected, via Unger's "Pinzette," to fire tongs attested in the Bronze Age Aegean and Egypt; this metallurgical reading is tied to the Idaean (hence iron) associations that explain Tudḫaliya IV's revival of the sign within the Hittite ideology linking sacred mountains, kingship, and iron. Second, the ethnonym Λέλεγες and a series of Lycian and Lydian onomastic and toponymic data (Dapara/Λαπαρας) are read as traces of Idaean, metallurgically connected populations. Third, the dynasty of Gurgum is argued to be of possible Mysian origin (Astuwaramanza, Marqasi, the -lara- names), with the element Lala-/Lara- analysed as a postnominal "Idaean" relational adjective extending, however tentatively, into the onomastics and cults of Hittite Anatolia.
