A liar will not be believed, even when he speaks the truth.

The gods help them who help themselves.

Once a wolf, always a wolf.

Never trust advice from a man in the throes of his own difficulty.

Any excuse will serve a tyrant.

A wild boar was sharpening his tusks upon the trunk of a tree in the forest when a fox came by and asked, Why are you doing that, pray? The huntsmen are not out today and there are no other dangers at hand that I can see. True, my friend, replied the Boar, but the instant my life is in danger, I shall need to use my tusks. There will be no time to sharpen them then.

Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.
