In an amusing Greek parable, Dionysius II teaches his courtier Damocles that luxury and wealth also come with responsibility and peril. This has given rise to the term 'Sword of Damocles'.
However, this is somewhat awkward, so sometimes the opposite term is encountered, in two varieties:
- 'Damoclean Sword'
- 'Damoclesean Sword'
I have found references to both. The first one seem to be more widely supported by dictionaries, but the second one makes more sense (to me).
Which is more correct?
