The Allegory of Patience by Giorgio Vasari

Patience is the virtue of the strong.

Those who are patient know how to achieve their goals, letting time pass by and catching the right opportunity.
Here is the beautiful painting by Giorgio Vasari, "Allegory of Patience". The artist turns this virtue into a young woman chained to a rock, who is patiently waiting for the water in the vase to corrode the chain drop by drop to set her finallly free.
