This has been all about the news in recent days. It’s pretty interesting: must have been an impressive hat when new! Alternative explanations, from the one given (Celtic cavalry serving in the Roman army) for the helmet include: it was a donative for tribal co-operation during the invasion or it was straight-up war booty (which might explain its possible ritual context of being buried with a huge coin hoard and pig bones). I did see one description of it that said it had a picture of a cavalry man trampling “a barbarian” but from the reconstruction drawing in the linked news article below this doesn’t seem apparent – the figure below the equestrian & winged victory seems separate to them, to my eye.
The decorated Roman cavalry helmet was discovered at a site in Leicestershire.
Experts said its date, close to the Roman invasion of 43 AD, meant it could be evidence of Celtic tribes serving with the Roman army.
The artefact, which was found in fragments, has been restored by a team at the British Museum.
