Philo was a prominent Roman writer and philosopher during the first century AD, it seems that in one of his books 'Against Flaccus' Philo mentions the multiple persecutions and punishments Jews of that time were facing, but it seems that the crucifixion wasn't mentioned?
I have some ideas why this would be, but I am not sure. Is it possibly because crucifixion was so commonplace that there was no need to mention it or was it the fact that Alexandria just didn't use this method of punishment? I think it is the latter because there is no historical evidences of crucifixion in Alexandria but I maybe wrong.
Because it is historically accepted citation needed that this was one of the most commonly used form of punishment in the Roman Empire starting from the BC period, there is historical evidencecitation needed in mainland Rome and it is accepted that they had brought this form of punishment everywhere they went.
Again, I have a question because I have read somewhere citation needed that Philo would go back to Jerusalem from time to time and it is historically established that crucifixion was taking place under Pontius Pilate and his successor during Philo's life time.
