Spartam nactus es; hanc exorna
"your lot is cast in Sparta, be a credit to it"
Note by A.J.Grieve from The Rational For Persecutions in Part 1 of Reflections On The Revolution In France

"having made your bed, now lie on it as comfortably as you can". The proverb is frequent in Latin literature, being taken from the 'Telephus' of Euripides, where it is addressed by Agamemnon to Menelaus.
