Biohazard Idols

Hit upon a program last night about the engineering of the ancient world, circa the Hellenistic Age.

No, not the usual bridges and aqueducts. This was about some sly tricks to accentuate worship. For example, the worship of Cybele, the multi-breasted mother goddess. Some brilliant scoundrel discovered that a strategically-placed altar fire could be used via principles of air pressure, to secretly force a bowl of sacrificial milk through a hidden tube into the body of the idol, squirting out copiously at the proper moment before the ecstatic worshippers and convincing them that she was lactating for their benefit.

What if some dastardly soul had figured out the secret and slipped a drop of dye into the milk bowl? What would the reaction have been, I wonder?
