"Thanks are justly due for boons unbought." -- Ovid. This is the most challenging quote I have yet encountered while playing cryptograms.
Here are some other quotes I've liked well enough to copy down:
"There is not a more unhappy being than a superannuated idol. " -- Joseph Addison
"The task of the modern educator is not to cut down jungles, but to irrigate deserts." -- C.S. Lewis
And it really is a desert out there. I think that is a good way to introduce some Latin bloopers, brought to you by 6th grade. If various 6th graders are to be believed,
- Virgil, not Vesuvius, destroyed Pompeii
- during the reign of Antoninus Pius, Rome was at its greatest expense
- Marcus Aurelius - the fall of Rome started at the end of his rein
- Hadrian - he was educated by the Geeks
- they will warn? - monebut
- "The enemys' part is in the hill."
- "On account of heaven Gaulls soldier's are in war."
- or is it "soilders"?
- Tiberius was the greatest orator in Rome.
