Persistence Prevails (from ancient latin).
Our saying "Durantes Vincunt" is due to an anecdote going back to Mr. Oronzio de Nora's school attendance.
When he was a teenager (and rather resolute by nature), he was in mild conflict with the Headmaster of his institute, who was in a position to fail him.
The Headmaster, as mathematics professor, was very severe and, at final examination, determined to fail the young Oronzio again.
After a very hard test, however, he had to recognise the excellent preparation of his student and said "you are the winner..." Mr. Oronzio's father congratulating his son on passing the exams, said "your saying should be DURANTES VINCUNT."
