Hi!
Oracle or not, you've got a great website!

Ages ago, in High School Latin, I learned a quotation that meant "Who will
watch the guards themselves?" I think it might have been from Cicero, but
I'm not sure. The last part was something like "custodiet ipsos custodies?"
but I could have the cases wrong because it's been a long time since I used my Latin much (which must seem just abominable to someone like you!)
Anyway, I wonder if you are familiar with the quotation and could supply
it for me? I'd really appreciate it.

Thanks
D

Dear D
"sed quis custodiet ipsos custodes" - and it's from Juvenal Satire VI -
though most of those who quote it don't know the original context!
"Bolt her in. Keep her indoors" "But who will guard ....?" "She is sensible.
She will begin with them."
Best wishes
Andrew
