Query: Proteomic and metagenomic insights into prehistoric Spanish Levantine
  Rock Art   The Iberian Mediterranean Basin is home to one of the largest groups of
prehistoric rock art sites in Europe. Despite the cultural relevance of
prehistoric Spanish Levantine rock art, pigment composition remains partially
unknown, and the nature of the binders used for painting has yet to be
disclosed. In this work, we present the first omic analysis applied to one of
the flagship Levantine rock art sites: the Valltorta ravine (Castell{\'o}n,
Spain). We used high-throughput sequencing to provide the first description of
the bacterial communities colonizing the rock art patina, which proved to be
dominated by Firmicutes species and might have a protective effect on the
paintings. Proteomic analysis was also performed on rock art microsamples in
order to determine the organic binders present in Levantine prehistoric rock
art pigments. This information could shed light on the controversial dating of
this UNESCO Cultural Heritage, and contribute to defining the chrono-cultural
framework of the societies responsible for these paintings.
