On first inspection, in their jars, or aquariums, or ouroboriums,
they appear to be simply domesticated serpents, writhing as they do
suspended in the ether. But of course, there's more to mythological
creatures, even domesticated varieties, than meets the eye. Know this
about the ouroborus: when one chooses to bite its own tail - a choice
which sooner or later every one of its kind is destined to make - it
cannot release it. It will spend the rest of its existence as a
never-ending loop. It might twist and writhe and flatten and flex,
but it is forever hooped.
