The legend of storks bringing babies stems from Attila's sack of Aquileia during his 452 A.D.
invasion of Italy.
When the Huns broke through the city's gates, parents rushed their infants to storks nesting on roof tops. As this was occurring, others dropped themselves over the
walls and paddled small boats down the river into the Adriatic marshes to escape the Huns.
Digna, the most beautiful young Roman woman in the city, tossed herself from the highest tower of the battlements to avoid being ravished by the horde, thus preserving her "dignity".
The people who escaped to the marshes were visited by the storks, bringing them the spared infants of the city. They built pole houses in the marshes which evolved into the city of Venice.
So storks bring babies, the birth of Venice, and the word "dignity", all came from Attila's sack of Aquileia.
