@olena I am suitably doubtful of most of the social media info as well - for instance, I couldn’t confirm it as being held in the Louvre (a common attribution in the social media posts). I went with ‘purported’ as again the connection to Hadrian’s villa is also unresolved in my book. The style though, in terms of the mosaic work itself, is plausibly ancient based on my years of looking at examples of mosaics from across Roman history. It’s certainly the case that the provenance may be murky while the artefact itself is still ancient. I’m very open to being wrong though!
