Chrispy would not have written the 'Medusa' one. This is because Medusa is a proper name and doesn't take an article (unless she's in French, and is a jellyfish) So, no 'the Medusa – she's Medusa the Gorgon, and has two sisters (Stheno and Euryale) both having her ophidian locks and petrifying personality who, not having been decapitated, are presumably still around.
My capacious if capricious memory has chucked up a piece of verse I met in the early sixties - I have no idea who wrote it, and have websearched it without success, but it went:
Medusa, Medusa, in days that were olden
Did you touch up your snakes, turning copper to golden?
Though snakes through the ages have never gon grey
They do have their problems in a practical way.
They take to the water, they slither when wet
Did you envy your victims their permanent set?
