There’s a lot of them here, some newer ones are quite beautiful, like this one at early XX century hydroelectric plant in Silesia, Poland:
But the best ones are IMO are those older, made by someone who newer actually saw a lion, like this one in Książ Castle, Poland:
Or even better, this one in Louvre museum in Paris:
It’s hard to even tell if that was intended to be a lion or some entirely different creature
