Jentilak (the Jentil / Gentiles)

In Basque tradition the jentilak are presented as an antediluvian or pre‑Christian race associated with the land itself. Etymologically the name comes from Latin gentilis and frames them as the non‑Christian 'gentiles'—ancestral builders and inhabitants of the region who explain the presence of prehistoric monuments. Sources vary in detail: the dominant narrative places them in a prior epoch, and some modern summaries note variant accounts that allow for coexistence with early humans, but the consistent emphasis is that the jentilak belong to a former age whose end is linked in folklore to Christianization.

Descriptions in the supplied sources emphasize great size and humanoid form: the jentilak are repeatedly called 'giants' or 'immense in size' and are depicted as hill‑dwellers. Specific physical details (skin, clothing, facial features) are not provided in the available material; their visual identity in these sources is primarily their enormous stature and association with crags and high places.

Folkloric attributions present the jentilak as master builders and powerful landscape workers: multiple sources credit them with the construction of dolmens, cromlechs, menhirs and other megalithic monuments and with actions such as 'beating the crags' to shape the terrain. They are described as possessing formidable strength and communal labour capacities. Morally they are variously characterized in popular summaries as 'rough but generally righteous' rather than purely malevolent. Their decline or disappearance is traditionally linked to the spread of Christianity; some modern accounts also note a folkloric reworking in which one jentil figure becomes Olentzero, a later cultural figure associated with gift‑giving in Christmas customs (presented in sources as a common folkloric link rather than an uncontested historical fact).
