I had never heard of Carnuntum, but I was struck by the notion of “oil lamps with depictions of gladiators” being sold as souvenirs. (Which reminds me of a Hercules (TV) episode were a vendor was selling Mt. Olympus souvenirs.) Turns out my mother has been to Carnuntum, and I didn’t even get a t-shirt.
