I’ve seen several (many?) different portrayals of Plato’s Cave and just now have noticed that many of them use monks (or similarly attired such folk) as the standard bearers. Given the timing (Plato vs Christian Church) it certainly could not have been the intent of Plato to suggest deception as a method of the church, but it appears to be the object of the artist(s).
A rational man might suspect that a rogue would welcome the sociological cover that the robes provide.
Just a thought.
