Let Sleeping Dogs Lie

Do you remember this sign I have posted at the beginning of this series? You see clearly that dogs/pets are not allowed inside.

However, all over Acropolis we spotted dogs and cats who seemed to call this historic city home. They were everywhere, lying in marble, on the ground, in gravel - sleeping, resting, minding their own business and not bothered by the tourists nor bothering any of the visitors either.

I read somewhere that the ancient Greeks believed that once they leave their human bodies in death, their souls pass thru being animals. Hence, they hold in esteem their dogs and cats as they may be the reincarnated Athena or Zeus.

Do you know where the proverb "Let Sleeping Dogs Lie" mean? It means that someone should not say something or do something that would cause someone else to be angry or to make trouble.

Furthermore, "let sleeping dogs lie" means for one not to disrupt a situation that is going well as it leads to problems.

If that metaphorical dog is just laying there asleep, leave him be. Don't go messing with him or he might wake up and bite you. [info from WikiAnswer]
