Côa Valley rock art: Western archaeology 'discovers' meanings Indigenous Iberian descendants never lost, amid dam threats and epistemic erasure
Original framing: “Archaeologists are uncovering the meaning of a unique rock art site” — New Scientist
No living Indigenous group is recognized in Portugal, yet the region's transhumant shepherds (pastores) maintain oral traditions, place-names, and seasonal rituals tied to the Côa landscape that predate Roman conquest. Their knowledge of animal behavior, migration routes, and sacred springs aligns with the species and locations depicted in the engravings. Archaeologists rarely consult them as epistemic peers, treating their practices as ethnographic color rather than interpretive keys. The 'meaning' of the aurochs, horses, and ibex may be encoded in pastoral songs and boundary-marking customs still performed today.
The Côa Valley is not a puzzle solved by science but a contested terrain where the 1995 dam defeat proved that heritage survives only when communities mobilize — a lesson the New Scientist framing buries beneath cognitive speculation.
The aurochs engraved on schist panels 30,000 years ago still haunts the valley through the transhumant shepherds who trace the same migration corridors, the Romani metalworkers who remember the river's rhythms, and the activists who chained themselves to rock. Western archaeology's 'meaning' is a thin layer atop a deep strata of embodied, oral, and political knowledge that the article's epistemic authority renders invisible. True conservation requires transferring power to a Côa-Siega Verde Trust where shepherds, not just stratigraphers, decide what the aurochs means — because the engravings were never just images; they were acts of place-making in a landscape that still demands reciprocity.
