Just because you can bring up Matthew Arnold doesn't mean you should

“...finally, it is said, he died by leaping into the crater of Etna to prove that he was a god. In the words of the [unknown] poet:

    'Great Empedocles, that ardent soul
    Lept into Etna, and was roasted whole.'

Matthew Arnold wrote a poem on this subject, but, although one of his worst, it does not contain the above couplet.”
