The best known and the most extensive of these lagoons is that in which Venice is situated, which extends from Torcello in the north to Chioggia and Brondolo in the south, a distance of above 40 m.; but they were formerly much more extensive, and afforded a continuous means of internal navigation, by what were called "the Seven Seas" (Septem Maria), from Ravenna to Altinum, a few miles north of Torcello.

In process of time some of these banks, as in the case of Venice, raised themselves above the level of the water and became the true shore-line, while behind them lay large surfaces of water, called lagoons, formed partly by the fresh water brought down by the rivers, partly by the salt-water tide which found its way in by the channels of the river mouths.

It is usually affirmed that the state of Venice owes its origin to the barbarian invasions of north Italy; that it was founded by refugees from the mainland cities who sought asylum from the Huns in the impregnable shallows and mud banks of the lagoons; and that the year 452, the year when Attila sacked Aquileia, may be taken as the birth-year of Venice.
The rivalries of the mainland cities were continued at closer quarters inside the narrow circuit of the lagoons, and there was, moreover, the initial schism between the indigenous fisher population and the town-bred refugees, and these facts constitute the first of the problems which now affronted the growing community: the internal problem of fusion and development.

The water in shallow seas, off the shores of islands or in lagoons, is saturated with calcium bicarbonate and if the amount of carbonic acid in solution be reduced by any means, normal carbonate must be precipitated.
There are, therefore, a number of agencies, all of which operate in shoal waters on the lee side of islands, or in shallow lagoons in such regions as the Bahamas, and the result of all these is to throw down calcium carbonate from solution in sea-water as minute needle-shaped crystals or little balls of aragonite.
