Pyrausta

This symbol, image and post is dedicated, if you didn't got an e-mail telling you that you are the one over who's dedicated, then, you are not that person. :-)

I was a happy child (but you know childhood ends, just to give Marillion a good Album), a happy child with access to books, knowledge, encyclopedias (and computers), a lot of symbols to explore, and a way of replacing dreams of traveling with some (non physical) activity :-)
In one encyclopedia of mythology, (and in one beautiful, very recommended book by J.L.Borges -The Book of the Imaginary Beings, again, complete here-, and in the Natural History by Pliny the Elder, here) I've found my favourite when I was a child: the pyrausta (also called pyrallis, pyragones), latin word for πυραύστης in ancient greek, a truly real butterfly which lives in the fire and dies if it leaves it; passionate being, in truth, in beauty, in goodness; sort of the antipodal point of me?, much more decadent... not sure. I believe this one killed Monster Acheron, by the way. :-)
It is something like a fire sparkle, but for the ulterior unbelievers. ;-)

That element, also, which is so destructive to matter, produces certain animals; for in the copper-smelting furnaces of Cyprus, in the very midst of the fire, there is to be seen flying about a four-footed animal with wings, the size of a large fly: this creature is called the "pyrallis", and by some the "pyrausta". So long as it remains in the fire it will live, but if it comes out and flies a little distance from it, it will instantly die.
