REDISCOVERED LATE UPPER PALEOLITHIC IMAGERY IN A CAVE IN BRITAIN:

The oldest cave art in Britain has been essentially rediscovered in Bacon Hole cave, on Gower Peninsula in South Wales. First seen in 1912 by Henri Breuil and Professor William Sollas they were called the first Paleolithic cave art in Britain. This was, however, dismissed by skeptics and subsequently ignored and all but forgotten, until recently. The painted marks have been looked up again and reexamined by scientists (Arnold 2026). Records of the cave painting, however, still existed.

“Following the rediscovery of the painted panel in 2022, the First Art team, in collaboration with dating specialists from the University of Southhampton, conducted two expeditions to Bacon Hole in 2023 and 2024. Both visits were commissioned by the National Trust and scheduled outside the bat hibernation season (October to April). The primary aim of these visits was to create a photographic record of the wall sections within the eastern side chamber, focusing particularly on the area surrounding the painted panel.” (Nash et al. 2026) The painting was rediscovered in September 2022. The international team of scientists conducted pigment analysis looking for organic residues, and collected samples from calcite flows for Uranium-Thorium dating on a vertical painted surface within a side chamber. (Nash et al. 2026) It is, perhaps, of note that the investigation occurred outside of bat hibernation season. This may have been done out of consideration for the wildlife, but my guess would be that it was prompted by the range of viruses carried by bats.

The teams did a quite complete job of studying and sampling the paint as well as the calcite layers on the cave wall. “In addition to the photographic survey, the painted surfaces originally discovered by Breuil and Sollas in 1912 were sampled to establish potential minimum and maximum date ranges. A total of twelve samples (six from each expedition) were collected. These included samples for both dating purposes (calcite overlapping pigments) and pigment geochemical analysis. The latter aimed to identify potential organic and inorganic binders using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy and Micro-Raman analysis.” (Nash et al. 2026)

 

The samples taken for Uranium-Thorium dating revealed a range of dates with the oldest being 15.7 ka (at a 95% confidence level). (Nash et al. 2026) Other dates came back from more recent eras, such as the Bronze Age.

The conclusions of the teams back up the original estimates by Breuil and Sollas. "Based on the evidence gathered from the two fieldwork visits, we concur with the original interpretation proposed by Breuil and Sollas in 1912 - that the horizontal lines (or streaks) represent anthropogenic activity. The painted lines are arranged horizontally and are equidistant from one another, indicating a deliberate and structured patternn. Furthermore, the hematite used to produce the ten lines likely derives from a single source, probably located at the rear of the side chamber" (Nash et al. 2026).

Bacon Hole also has a wide range of images, scribbles and initials from since the time of the original painting (see Nash et al. below).
