It would’ve been madness in that region at that time. The Romans were writing entire books on natural history and that’s not even getting into something like the lost works on the Etruscan civilization. Recording things in that way fell out of favor with the Jewish people at that time due to centuries of rather brutal occupation requiring a certain level of obfuscation. Though I will say that objectivism wasn’t a concept at that point, the Garlic Wars is as much an account as it is propaganda by Caesar.
