Echoes of La Tène in Bohemia

From the silver sheen of decorated swords to the quiet rows of village houses, the La Tène horizon swept across Central Europe in the first millennium BCE. In Bohemia, archaeological sequences show a transition from late Hallstatt traditions into the vibrant La Tène artistic and material world between the 5th and 1st centuries BCE. Sites sampled for ancient DNA — Prague‑Jinonice (Holman’s Garden Centre) and the Radosevice cemeteries I and II near Teplice — lie within landscapes of rivers and trade routes that tied Bohemia into long-distance exchange networks.

Archaeological data indicates intensified metalworking, standardized weapon types, and characteristic curvilinear decoration that signal a shared cultural vocabulary across disparate settlements. Radiocarbon-calibrated contexts at these cemeteries place individuals securely between 480 BCE and 44 BCE, the core La Tène interval in the region. Material culture suggests links to wider ‘Celtic’ identities recognized by classical authors, but linking language, identity, and genetics requires caution: cultural style does not equate directly to ancestry.

The 59 genomes in this dataset offer a regional snapshot: they document local funerary practice and population composition in Central and NW Bohemia during the La Tène. While archaeologically unmistakable as La Tène, genetic interpretations must weigh mobility, marriage networks, and long-term population processes visible only when combined with broader comparative datasets.

The genetic dataset from Czech_IA_LaTene comprises 59 individuals dated 480–44 BCE, large enough to assess regional maternal lineages with some confidence. Mitochondrial DNA shows a dominance of haplogroup H (20 individuals), followed by U (8), K (5), J (4) and a recurrent sublineage H5c (3). Haplogroup H is widespread in Europe from the Neolithic onward and its prominence here is consistent with long-term maternal continuity in Central Europe.

No consistent, reportable pattern for Y‑chromosome haplogroups is available in this dataset (common Y-DNA values not reported), which restricts inferences about paternal continuity, patrilineal structure, or male-mediated migration. Archaeogenetic studies of other La Tène contexts often reveal mixed ancestry: substantial local (Neolithic farmer and later Bronze Age) components combined with steppe-derived contributions that entered Europe in earlier millennia. Limited evidence from the Bohemian La Tène samples suggests a local population profile shaped by these deep histories plus Iron Age mobility, but precise proportions of ancestry components require formal admixture modeling against comparative panels.

Crucially, genetics here refines archaeological narratives: mtDNA patterns support regional maternal continuity through the Iron Age, while the absent/limited Y-DNA reporting prevents strong claims about male lineage turnover. Linking this genetic makeup to language or ethnic identity remains speculative; DNA records biological relationships, not cultural labels.
