Oplomachus nunc es, fueras opthalmics ante.
Fecisti medicus quod facis oplomachus.<sup>1</sup>
Marcus Valerius Martialis was a Roman poet from modern-day Calatayud.
He was also the original insult comic. Even a loose translation should suffice to make the case.
You’re a gladiator now — you were a doctor before.
The scalpel prepared you well for the sword.
1. Martial, Epig. 8.74
