Still waters run deep.
The Roman historian Quintus Curtius Rufus, writing about Alexander the Great in the 1st century AD, recorded ‘the deepest rivers flow with the least sound’ as a proverb from Bactria, in Central Asia. Today the saying usually means that a quiet person may have deep feelings or a sharp mind. It was once a warning too: a calm surface can hide danger. The French still say there is no worse water than sleeping water, and a Turkish saying warns that a meek, downcast look can hide mischief.
